Protective Measures for Sensitive Groups

When air quality is unhealthy for sensitive groups, everyone is at risk for eye, skin, and throat irritation, as well as respiratory problems. The public should greatly reduce outdoor exertion.

While the broader population might still be largely unaffected, sensitive groups are at much greater health risk and should be very cautious. They should avoid all outdoor activity.

How can I protect myself when air quality is unhealthy for sensitive groups?

Get a free air quality app for real-time air quality alerts and forecasts and consistently monitor your air quality.
Help increase the amount of ground-level monitors by becoming an air quality contributor. Contribute to your community’s outdoor air quality data.
Shut doors and windows and set the HVAC to recirculate mode.
Sensitive groups should stay indoors; if you do need to go outdoors, wear a KN95/FFP2 mask.
Run a high-performance air purifier to filter pollutants, particles, gases, and other contaminants

A kitten rescue in Ontario needed a powerful clean air solution fast – and found it. Learn more about the essential role of clean air in shelters.

","Nestled in a small town near Cornwall, Canada, Tiny but Mighty Kitten Rescue serves as a lifeline for abandoned and vulnerable kittens (1). For nearly eight years, rescue founder Mellissa has worked tirelessly to save and nurture the most fragile feline lives in the region. Yet despite Mellissa’s dedication to maintaining a clean environment for those in her care, animal rescues must always contend with a formidable health challenge. Poor air quality impacts both kittens and the humans who care for them. Thanks to advanced air purification technology, the rescue now breathes easier—literally and figuratively. Mission built on compassion Mellissa’s journey to creating Tiny but Mighty began with heartbreak. As a volunteer at her local animal shelter, she learned of the euthanasia of kittens deemed too young to care for. Unwilling to accept this outcome, she founded her own kitten-focused rescue in 2017. “I had so many dreams about saving these kittens. Something told me to just do it myself—start my own rescue.” “I had so many dreams about saving these kittens. They wouldn’t let up,” Mellissa shared. “Something told me to just do it myself—start my own rescue.” Mellissa provides a safe space for kittens to grow and thrive until they find their carefully screened forever homes. Today, the rescue operates solely on donations and community support. “It’s such an incredible community. People do come through to support what I’m doing, so it’s incredible.” But running a rescue isn’t without its challenges, and one significant one she uncovered was air quality. Nova the kitten enjoying toys at the Tiny but Mighty Kitten Rescue. Good air quality: Essential in animal rescues Caring for kittens in any enclosed environment presents unique challenges. Despite her meticulous cleaning habits, Mellissa found air quality to be a problem. “The dust is crazy. The kittens will go in their litter box and sneeze.” There would still be dust, odors, and allergens in the space “even though I use 99% dust-free litter.” Mellissa explained. “It’s great compared to some I’ve tried, but the dust is crazy. The kittens will go in their litter box and make little sneezes.” This poor air quality not only affected visitors but also had potential health implications for the kittens and Mellissa herself. Dust mites, microscopic creatures that feed on animal’s dead skin, can cause year-round allergic reactions in both cats and humans, including sneezing, runny and itchy noses, watery eyes, and even rashes. Components of pet dander can also act as an allergen, triggering similar reactions. Determined to find a solution to her dust problem, she began her search for an air purifier that could meet the rescue’s unique needs. Life changing air cleaning solution Determined to tackle the persistent dust and allergens, Mellissa sought an air purifier that could truly meet the unique demands of her rescue. After years of frustration with a previous model, she knew she needed a solution that could handle constant activity, fine dust particles, and odors effectively. Mellissa recalled, “The dust was still spreading throughout the house, and I thought, ‘this is just not enough.’” That’s when Mellissa’s father suggested looking into IQAir’s HealthPro Plus XE. Intrigued by its reputation for advanced filtration capabilities, Mellissa decided to give it a try—and the results were immediate and noticeable.

Nestled in a small town near Cornwall, Canada, Tiny but Mighty Kitten Rescue serves as a lifeline for abandoned and vulnerable kittens (1). For nearly eight years, rescue founder Mellissa has worked tirelessly to save and nurture the most fragile feline lives in the region.

Yet despite Mellissa’s dedication to maintaining a clean environment for those in her care, animal rescues must always contend with a formidable health challenge. Poor air quality impacts both kittens and the humans who care for them.

Thanks to advanced air purification technology, the rescue now breathes easier—literally and figuratively.

Mission built on compassion

Mellissa’s journey to creating Tiny but Mighty began with heartbreak. As a volunteer at her local animal shelter, she learned of the euthanasia of kittens deemed too young to care for. Unwilling to accept this outcome, she founded her own kitten-focused rescue in 2017.

“I had so many dreams about saving these kittens. Something told me to just do it myself—start my own rescue.”

“I had so many dreams about saving these kittens. They wouldn’t let up,” Mellissa shared. “Something told me to just do it myself—start my own rescue.”

Mellissa provides a safe space for kittens to grow and thrive until they find their carefully screened forever homes. Today, the rescue operates solely on donations and community support. “It’s such an incredible community. People do come through to support what I’m doing, so it’s incredible.”

But running a rescue isn’t without its challenges, and one significant one she uncovered was air quality.

Good air quality: Essential in animal rescues

Caring for kittens in any enclosed environment presents unique challenges. Despite her meticulous cleaning habits, Mellissa found air quality to be a problem.

“The dust is crazy. The kittens will go in their litter box and sneeze.”

There would still be dust, odors, and allergens in the space “even though I use 99% dust-free litter.” Mellissa explained. “It’s great compared to some I’ve tried, but the dust is crazy. The kittens will go in their litter box and make little sneezes.”

This poor air quality not only affected visitors but also had potential health implications for the kittens and Mellissa herself. Dust mites, microscopic creatures that feed on animal’s dead skin, can cause year-round allergic reactions in both cats and humans, including sneezing, runny and itchy noses, watery eyes, and even rashes.

Components of pet dander can also act as an allergen, triggering similar reactions.

Determined to find a solution to her dust problem, she began her search for an air purifier that could meet the rescue’s unique needs.

Life changing air cleaning solution

Determined to tackle the persistent dust and allergens, Mellissa sought an air purifier that could truly meet the unique demands of her rescue. After years of frustration with a previous model, she knew she needed a solution that could handle constant activity, fine dust particles, and odors effectively.

Mellissa recalled, “The dust was still spreading throughout the house, and I thought, ‘this is just not enough.’”

That’s when Mellissa’s father suggested looking into IQAir’s HealthPro Plus XE. Intrigued by its reputation for advanced filtration capabilities, Mellissa decided to give it a try—and the results were immediate and noticeable.

The HealthPro Plus XE is equipped with HyperHEPA filtration, capable of capturing particles as small as 0.003 microns—100 times smaller than most air purifiers can filter. This efficiency, proven to remove particles far smaller than bacteria or viruses, combined with gas-phase filtration to eliminate odors, made it an ideal solution for the rescue’s air quality challenges.

“The kittens aren’t sneezing anymore. The air purifier has had a huge impact,” Mellissa shared.

WWF Pakistan is tackling air pollution with IQAir. Learn how real-time data is driving change across the country.

","In Pakistan, severe air pollution silently impacts public health and well-being nationwide. Yet, due to a dire lack of air quality data, air quality monitors, and public awareness, the scale of the threat remains largely unseen. In 2024, Pakistan was the third most polluted country in the world, with an average PM2.5 concentration of 73.7 μg/m3 and exceeding the World Health Organization’s recommended annual guideline of 5 μg/m3 by 14.7 times. Numerous cities experienced poor air quality, with high average PM2.5 concentrations measured for Islamabad (52.4 μg/m3), Rawalpindi (65.8 μg/m3), Faisalabad (88.8 μg/m3), Peshawar (91.0 μg/m3), and Lahore (102.1 μg/m3) – all exceeding the WHO recommended guideline by ten times or more. Recognizing the urgency of this crisis, WWF-Pakistan has taken significant steps to address air pollution using IQAir’s air quality monitoring technology. WWF-Pakistan has successfully deployed stations across Pakistan and published data to IQAir’s AirVisual platform, establishing the country’s largest air quality monitoring network. With this initiative, WWF-Pakistan is transforming how the country understands and confronts this invisible threat. \"We have successfully reached the goal of installing AirVisual Outdoor sensors in 15 of our offices across Pakistan,\" said WWF-Pakistan’s Research Officer, Muhammad Huzaifa who led this initiative in Pakistan. As of now, WWF-Pakistan has air monitoring stations located in key regions like Karachi, Lahore, Quetta, Multan, and Peshawar. They provide real-time data that is accessible to both policymakers and the public. \"We are excited to say that we’ve published the data from these stations to IQAir’s platform, where communities can see their local air quality in real-time.” Why Pakistan Needs Reliable Air Quality Data Pakistan's urban centers, such as Lahore, Peshawar and Karachi, frequently grapple with thick layers of smog. While this is a visible reminder of air pollution, the more dangerous pollutants often remain unseen and unmonitored. One of the greatest challenges in Pakistan has been the need for more reliable, public air quality data. \"Our air quality network provides crucial air quality data in some of Pakistan’s most polluted regions and are often ranked among the top 10 most polluted cities in the world\" Huzaifa explained. WWF-Pakistan, the nation’s largest environmental organization, has been addressing critical environmental issues since 1970. Originally focused on protecting wildlife and ecosystems, the organization’s scope has broadened to include tackling climate change, protecting vulnerable habitats, and securing vital resources like freshwater. Now, through their air quality monitoring initiative, they are addressing one of the most pressing health and environmental crises facing Pakistan. “Unfortunately, there is little public air quality data available,” Huzaifa noted. “This information vacuum has left policymakers and citizens unprepared to tackle the pollution crisis.” WWF-Pakistan’s initiative helps fill this gap, ensuring the public has access to real-time, localized air quality data. With real-time data now available, citizens, governments, and policymakers can work together to implement solutions, reduce pollution and improve health outcomes across the country. Building Pakistan's National Air Quality Network WWF-Pakistan’s initiative, which involves installing air quality sensors in key cities across the country, marks a critical step in Pakistan’s battle against air pollution. By coordinating 15 monitoring stations under one national initiative, WWF-Pakistan now operates the country’s largest organized air quality monitoring network, making real-time data accessible to both citizens and policymakers. Partnering with IQAir adds both credibility and precision to the project. \"IQAir's AirVisual air quality monitors are globally recognized for their accuracy and ability to track even the smallest fluctuations in air quality,\" said Huzaifa. \"IQAir's technology is built to withstand all sorts of weather and having it in place ensures that people will trust the data.\" This transparency is essential for mobilizing both community efforts and policy interventions, as reliable information is crucial to driving meaningful change. Using Air Quality Data to Combat Pollution in Pakistan With the sensors online and data flowing into the IQAir platform, WWF-Pakistan's live contributor profile showcases the impact of their work, allowing anyone to monitor air quality in real-time. This transparency empowers citizens and policymakers alike to take informed action, using reliable data to drive meaningful change across the country. Explore WWF-Pakistan’s profile to see the live data from their monitoring stations across Pakistan. \"Data isn’t just a tool for awareness—it’s the foundation for meaningful action,\" Nazifa Butt, Director Climate Action and Sustainability WWF-Pakistan emphasized. “Now that we have the data, we have something to report and base our decisions on.” Nazifa emphasized the importance of storytelling. “We’re going to have to tell two parts of the story,” she explained, pointing out how data can not only expose alarming trends but also inspire communities to push for change—through policies, advocacy, and local initiatives. With 18,800 followers across its national network, WWF-Pakistan is sharing that data every day with citizens who urgently need real-time air quality information to help protect themselves from pollution. Pakistan's Long-Term Pollution Solutions WWF-Pakistan envisions a future where every region of the country has access to real-time, accurate air quality data. \"Each sensor we deploy is a step closer to a healthier, more sustainable Pakistan,\" Nazifa explained. By providing access to this data, WWF-Pakistan aims to foster a culture of proactive health management, where individuals and communities can take the steps necessary to protect themselves from pollution. The air quality data being gathered is more than just numbers—it’s a lifeline for communities struggling with the dangers of polluted air. “Our initiative is laying the foundation for a National Clean Air Research Centre,\" Huzaifa said. \"This will be a hub for research and data-driven policies, enabling us to tackle pollution with innovative strategies.\" “Each sensor we deploy is a step closer to a healthier, more sustainable Pakistan.” In October 2024, WWF-Pakistan warned that Lahore’s air quality posed a terrible threat to public health, recommending a number of changes to government policy including helping farmers manage crop waste, expanding mass transit, and improving zoning laws to reduce industrial pollution away from residents. It also noted that low-cost air quality monitoring systems could be used to uncover air pollution hotspots along traffic routes. Armed with that information, governments could restrict heavy transport vehicles or develop alternate routes to avoid congestion (1). Beyond their air quality monitoring project, the WWF-Pakistan team oversees more than 60 active environmental protection initiatives in FY 2025 across the country, ranging from clean water access and forest preservation to sustainable infrastructure development. These efforts, working in tandem with the air quality monitoring network, are all part of WWF's broader mission to protect the planet's natural environment and create a future where both people and nature can thrive in harmony. Conclusion WWF-Pakistan's initiative is a testament to the transformative power of air quality data, technology, and collective will in addressing one of today’s most pressing challenges. And by increasing the footprint of air quality monitors across the country, innovative solutions to persistent pollution problems can be put into play. As this vital work advances, it invites everyone to contribute to the cause—because in the fight for clean air, every voice and every action matters. “This initiative,” Nazifa said, “lays the foundation for what we envision as Pakistan’s future air quality innovation hub. It will serve as a hub for developing strategies and methods to tackle air pollution, aligning efforts across governmental and non-governmental sectors, both locally and internationally, in the fight against climate change.”","

Numerous cities experienced poor air quality, with high average PM2.5 concentrations measured for Islamabad (52.4 μg/m3), Rawalpindi (65.8 μg/m3), Faisalabad (88.8 μg/m3), Peshawar (91.0 μg/m3), and Lahore (102.1 μg/m3) – all exceeding the WHO recommended guideline by ten times or more.

Recognizing the urgency of this crisis, WWF-Pakistan has taken significant steps to address air pollution using IQAir’s air quality monitoring technology. WWF-Pakistan has successfully deployed stations across Pakistan and published data to IQAir’s AirVisual platform, establishing the country’s largest air quality monitoring network. With this initiative, WWF-Pakistan is transforming how the country understands and confronts this invisible threat.

\"We have successfully reached the goal of installing AirVisual Outdoor sensors in 15 of our offices across Pakistan,\" said WWF-Pakistan’s Research Officer, Muhammad Huzaifa who led this initiative in Pakistan.

As of now, WWF-Pakistan has air monitoring stations located in key regions like Karachi, Lahore, Quetta, Multan, and Peshawar. They provide real-time data that is accessible to both policymakers and the public. \"We are excited to say that we’ve published the data from these stations to IQAir’s platform, where communities can see their local air quality in real-time.”

Why Pakistan Needs Reliable Air Quality Data

Pakistan's urban centers, such as Lahore, Peshawar and Karachi, frequently grapple with thick layers of smog. While this is a visible reminder of air pollution, the more dangerous pollutants often remain unseen and unmonitored. One of the greatest challenges in Pakistan has been the need for more reliable, public air quality data.

\"Our air quality network provides crucial air quality data in some of Pakistan’s most polluted regions and are often ranked among the top 10 most polluted cities in the world\" Huzaifa explained.

WWF-Pakistan, the nation’s largest environmental organization, has been addressing critical environmental issues since 1970. Originally focused on protecting wildlife and ecosystems, the organization’s scope has broadened to include tackling climate change, protecting vulnerable habitats, and securing vital resources like freshwater. Now, through their air quality monitoring initiative, they are addressing one of the most pressing health and environmental crises facing Pakistan.

“Unfortunately, there is little public air quality data available,” Huzaifa noted. “This information vacuum has left policymakers and citizens unprepared to tackle the pollution crisis.” WWF-Pakistan’s initiative helps fill this gap, ensuring the public has access to real-time, localized air quality data.

With real-time data now available, citizens, governments, and policymakers can work together to implement solutions, reduce pollution and improve health outcomes across the country.

Building Pakistan's National Air Quality Network

WWF-Pakistan’s initiative, which involves installing air quality sensors in key cities across the country, marks a critical step in Pakistan’s battle against air pollution. By coordinating 15 monitoring stations under one national initiative, WWF-Pakistan now operates the country’s largest organized air quality monitoring network, making real-time data accessible to both citizens and policymakers.

Partnering with IQAir adds both credibility and precision to the project. \"IQAir's AirVisual air quality monitors are globally recognized for their accuracy and ability to track even the smallest fluctuations in air quality,\" said Huzaifa. \"IQAir's technology is built to withstand all sorts of weather and having it in place ensures that people will trust the data.\" This transparency is essential for mobilizing both community efforts and policy interventions, as reliable information is crucial to driving meaningful change.

Using Air Quality Data to Combat Pollution in Pakistan

With the sensors online and data flowing into the IQAir platform, WWF-Pakistan's live contributor profile showcases the impact of their work, allowing anyone to monitor air quality in real-time. This transparency empowers citizens and policymakers alike to take informed action, using reliable data to drive meaningful change across the country. Explore WWF-Pakistan’s profile to see the live data from their monitoring stations across Pakistan.

\"Data isn’t just a tool for awareness—it’s the foundation for meaningful action,\" Nazifa Butt, Director Climate Action and Sustainability WWF-Pakistan emphasized. “Now that we have the data, we have something to report and base our decisions on.”

Nazifa emphasized the importance of storytelling. “We’re going to have to tell two parts of the story,” she explained, pointing out how data can not only expose alarming trends but also inspire communities to push for change—through policies, advocacy, and local initiatives.

With 18,800 followers across its national network, WWF-Pakistan is sharing that data every day with citizens who urgently need real-time air quality information to help protect themselves from pollution.

Pakistan's Long-Term Pollution Solutions

WWF-Pakistan envisions a future where every region of the country has access to real-time, accurate air quality data.

\"Each sensor we deploy is a step closer to a healthier, more sustainable Pakistan,\" Nazifa explained. By providing access to this data, WWF-Pakistan aims to foster a culture of proactive health management, where individuals and communities can take the steps necessary to protect themselves from pollution.

The air quality data being gathered is more than just numbers—it’s a lifeline for communities struggling with the dangers of polluted air. “Our initiative is laying the foundation for a National Clean Air Research Centre,\" Huzaifa said. \"This will be a hub for research and data-driven policies, enabling us to tackle pollution with innovative strategies.\"

“Each sensor we deploy is a step closer to a healthier, more sustainable Pakistan.”

In October 2024, WWF-Pakistan warned that Lahore’s air quality posed a terrible threat to public health, recommending a number of changes to government policy including helping farmers manage crop waste, expanding mass transit, and improving zoning laws to reduce industrial pollution away from residents.

It also noted that low-cost air quality monitoring systems could be used to uncover air pollution hotspots along traffic routes. Armed with that information, governments could restrict heavy transport vehicles or develop alternate routes to avoid congestion (1).

Beyond their air quality monitoring project, the WWF-Pakistan team oversees more than 60 active environmental protection initiatives in FY 2025 across the country, ranging from clean water access and forest preservation to sustainable infrastructure development. These efforts, working in tandem with the air quality monitoring network, are all part of WWF's broader mission to protect the planet's natural environment and create a future where both people and nature can thrive in harmony.

Conclusion

WWF-Pakistan's initiative is a testament to the transformative power of air quality data, technology, and collective will in addressing one of today’s most pressing challenges. And by increasing the footprint of air quality monitors across the country, innovative solutions to persistent pollution problems can be put into play.

As this vital work advances, it invites everyone to contribute to the cause—because in the fight for clean air, every voice and every action matters.

“This initiative,” Nazifa said, “lays the foundation for what we envision as Pakistan’s future air quality innovation hub. It will serve as a hub for developing strategies and methods to tackle air pollution, aligning efforts across governmental and non-governmental sectors, both locally and internationally, in the fight against climate change.”

Are scented candles bad for you?

Burning a scented candle is a popular way to create a pleasant ambiance at home. Scents such aslavender, jasmine, and sandalwood can be relaxing and invigorating. During the holidays, many people find the warm glow and aroma of pine, gingerbread, or cinnamon makes a room feel more festive.

Unfortunately, most mass-produced scented candles can have a negative impact on indoor air quality. From the wax to the wick to the fragrance itself, the average scented candle can release harmful chemicals into the air — even when unlit.

From the wax to the wick to the fragrance itself, the average scented candle can release harmful chemicals into the air — even when unlit.

So while you and your family may enjoy the fragrance of scented candles in your home, they may be harmful to your health. Read on to learn why some candles are bad for you.

Paraffin wax

Are paraffin wax candles safe? In what way can wax be harmful?

According to a 2017 study in the International Journal of Tropical Disease and Health, paraffin candles emit pollutants that can threaten human health and shouldn’t be burned in enclosed areas (1).

Most candles are made from paraffin, a petroleum byproduct. To create paraffin wax candles, petroleum waste is chemically bleached, deodorized, and made into wax. When burned, paraffin wax can release toxicvolatile organic compounds (VOCs) into the air, including known carcinogens like:

alkenes
acetone
benzene
toluene

These are the same chemicals found in diesel fuel emissions and are known to cause allergies, asthma attacks, and skin problems.

A 2005 study published by the University of South Florida showed that candles made of paraffin wax emit low levels of benzene even when they are not lit (2).

Is burning candles bad for you?

In addition to releasing toxic chemicals, burning paraffin wax produces soot composed of particulate matter such as, PM2.5 and ultrafine particles that can remain suspended in the air for hours. According to the University of South Florida study, ultrafine soot particles are similar to diesel exhaust in both their size and composition. They penetrate deeply into the lungs and are absorbed into the blood stream (3).

A 2000 study conducted by the U.S. Environmental Protection Agency showed that soot emissions from candles are significantly higher after wax breakthrough occurs and when a candle is smoldering (4).

Ultrafine particles are associated with severe health issues, including:

allergies
asthma
COPD (5)
respiratory tract infections
heart attacks
strokes
cancer

So, are candles bad for your health? Not all candles produce the same amount of air pollutants. A 2002 study published in theJournal of the American Oil Chemists’ Society found that soywax, much like beeswax candles, burned at a significantly lower rate and resulted in less soot than paraffin candles (6).

Chemical fragrances

Another problem with scented candles is that the chemicals they use to create a pleasing aroma are generally far from wholesome.

Most scented candles use synthetic fragrances and dyes that give off dangerous VOCs even at room temperature.

Most scented candles use synthetic fragrances and dyes that give off dangerous VOCs even at room temperature. Commonly emitted VOCs related to the scent in candles include (7):

formaldehyde
petroleum distillates
limonene
alcohol
esters

These harmful chemicals can cause health problems, such as:

headaches
dizziness
allergy symptoms
asthma attacks
respiratory tract infections
cancer
\n\n\t

Cored wicks

Many candles have cored wicks made from cotton that are wrapped around a metal support. The design helps keep the wick from falling over into the wax. This is especially useful for scented candles because the fragrance oils soften the wax and allow non-cored wicks to go limp.

Are candles toxic? If they have lead in them, possibly. Lead was once commonly used in cored candlewicks — especially in candles imported from overseas. However, after determining that these wicks could present a lead poisoning hazard to young children, the U.S. Consumer Product Safety Commission banned the manufacture and sale of all candles with lead-core wicks in 2003 (8). Zinc and tin have been used as a substitute since the ban.

All metal-core wicks release trace amounts of heavy metals into the air when they are burned.

However, all metal-core wicks release trace amounts of heavy metals into the air when they are burned. Wicks with zinc and tin cores can still release small amounts of lead particles (9,10).

Safer alternatives

To limit soot stains and poor air quality in your home, you should avoid or restrict the use of candles (11).

If you still crave the pleasant ambiance and aroma of scented candles, here are safer ways to scent the air:

\nUse essential oils for fragrance.Essential oils can be placed in a diffuser or in bathwater to create a desired aroma.
\nSimmer spices.Place spices such as cinnamon sticks, cloves, and nutmeg in a pot of water and let it simmer on the stove.
\nCreate potpourri.Dried items such as flowers, berries, fruit rinds, wood chips, and spices can be placed in bowls or fabric bags and placed around your home.

The takeaway

Lighting scented candles may seem like a relaxing way to enjoy your home. But burning scented candles releases VOC pollutants and worsens your home’s indoor air quality. Although fragrances from safer alternatives like essential oils can be pleasant, trulyclean air smells like nothing at all.

Himalayan salt lamps DO NOT purify indoor air.

These trendy little lamps consist of a light bulb placed inside a chunk of pink Himalayan salt. They’re easily recognized by their hand-carved, often stylized shapes and dim, pinkish glow they emit when light shines through them.

They’ve been gaining popularity for years, mostly because their distinct color and unique appearance make them attractive objects for interior decoration, and their glow can add a pleasing atmosphere to a room.

But their recent rise in popularity as “natural” air purifiers should trouble you.

A host of (often misleading) studies supporting the use of salt in treating respiratory conditions have escalated demand for these little pink things, especially within the well-primed alternative medicine market, full of people who may already be seeking home remedies for all sorts of health conditions and indoor environmental issues when modern medicine hasn’t seemed to help.

And you shouldn’t buy a Himalayan salt lamp to purify your air for one major reason: they’re negative ionizers, and negative ionization is one of the most absurd air purification myths ever devised.

Why are Himalayan salt lamps bad for air quality?

Again, two words: negative ionization.

If you ever hear the words “ionization” (in one form or another) and “air purification” in the same sentence, you should run in the opposite direction.

In the context of air purification, negative ionization happens when negatively charged particles attach themselves, or “charge,” pollutant particles in the air, effectively removing them from ambient air by causing them to stick to nearby surfaces.

This phenomenon also occurs in nature – know that distinct smell in the air after a thunderstorm? That’s the result of “atmospheric space charge” as air ions are generated by the electric fields of storms.¹ Many air purifiers and purification devices sold in stores, including Himalayan salt lamps and a variety of “air ionizers,” artificially produce high voltage to achieve this same effect.

The problem with negative ionization, though, is that it doesn’t actually remove pollutants from your indoor air – it just causes the particles to adhere themselves to nearby surfaces, where they’re easily stirred up by indoor activities like dusting, vacuuming, and ventilation.

Charged particles can also stick to your respiratory tract, where charged particles can settle in your windpipe and lungs and cause even more harm that if they’d just remained in the air. Studies show that these particles can penetrate deep into your respiratory system and cause both heart and lung conditions.²

The average, nightstand-sized Himalayan salt lamp generates only a small number of negative ions into the air, so you may not notice any tangible change in your air quality or health, at least immediately. But these lamps can be huge: you can buy salt lamps that weight up to 300 pounds for thousands of dollars, and their ionization effects may have a more noticeable effect on your air, especially if you live in an airtight, energy-efficient home in which indoor pollutants have a much harder time getting out.

And negative ionizers have another dark secret: they can also create indoor ozone (O₃).

There are two main types of ozone:

\nStratospheric ozone: Alayer of ozone occurs naturally several miles up in the atmosphere, where it protects the surface of the earth (and people’s skin) from ultraviolet (UV) radiation from the sun.
\nTropospheric ozone: Also called ground-level ozone or smog, ground-level ozone tends to develop when heat from sunlight reacts with chemicals near the ground, many of which are produced by emissions from vehicle exhaust and factory smoke.

Negative ionization can generate tropospheric ozone indoors. While stratospheric ozone has no interaction with us in the lower atmosphere, ground-level ozone is far more harmful when it builds up to high levels. And perhaps one of the starkest examples of ground-level ozone is one that millions of us know very well – the smog that forms in major cities during rush hour.

If you live near a freeway, dense urban center, or even at a high elevation where you can see the area around an urban area. A few hours or less after rush hour begins and the sun begins to rise, you’ll start to notice a visible layer of haze build up. This is ground-level ozone, and even though it’s a typical feature of modern life, extensive research shows that it causes a plethora of immediate symptoms, including:

Coughing
Wheezing
Trouble breathing
Stuffy nose
Dizziness
Tingling in arms and legs
Fever^3,4\n

Further research suggests that ozone is also responsible for long-term health problems, such as asthma, heart disease, and lung disease. Emerging studies on rats also suggest that ozone could cause seizures and blindness.

So even though you may not get rush-hour levels of ozone in your home from a salt lamp, indoor ozone buildup can indeed cause some disruptive health effects if you don’t follow best practices for good Indoor Air Quality.

So what’s so special about Himalayan salt?

So how did someone come up with the idea that Himalayan salt lamps have any health effects at all?

The story stretches back millennia. Truly authentic Himalayan salt comes from the Khewra salt reserves in the Punjab region of Pakistan. Salt mined here is thought to be millions of years old and contain numerous minerals.

Salt lamps have been proposed for use in treatments for conditions like chronic obstructive pulmonary disease (COPD) because of their purported therapeutic effects on your respiratory system. This treatment even has a clinical term: halotherapy, based on an ages-old respiratory treatment technique known as speleotherapy.

Stable air temperature
Moderate to high humidity
Presence of aerosol elements, such as sodium, potassium, and magnesium
Lack of airborne pollutants

Halotherapy takes the notion that salt cave environments are good for respiratory health by having people inhale small amounts of salt particles that are released into the ambient air of a controlled room to “reproduce” a salt cave’s microclimate. But there’s no conclusive evidence that either speleotherapy or halotherapy actually relieve respiratory symptoms.⁶

Let's look more critically at air purification.","The home air purifier market has undergone many shifts and starts in its decades-long history as an affordable solution for indoor air quality. Along with those shifts have been seemingly ground breaking advancements in filtration technologies that may seem like the next revolution in air purification. But not all air purifiers safely clean the air. Not all air purifiers safely clean the air. Let's take an evidence-based approach to the industry and separate the fact from the fiction. What should I look for in an air purifier? Before we examine the various air purifiers on the market with a critical eye, it’s essential to have a solid understanding of what does make a good air purifier. 1. HEPA filters are the standard for the industry. What is a HEPA filter? High-efficiency particulate air (HEPA) filters capture airborne particles from moving air using a dense, random arrangement of fibers. HEPA filters use the physics of particles moving through air to yank them out of the air flow. Their operation is simple but extremely effective, and HEPA filters are now standard issue for almost every air purifier on the market. But it wasn’t always that way. Air purifiers have been around for well over a century. The first air purification systems appeared in the 1850s in charcoal-based masks used by coal miners. They were designed to keep toxic dust out of their lungs. The technology was so successful that, less than twenty years later, respirators were added to these types of masks to protect firefighters from breathing in smoke chemicals and pollutants (1). Beginning in the 1940s, the United States Atomic Energy Commission started experimenting with high-efficiency particulate arrestance, better known now as HEPA, as a method of shielding soldiers from atomic radiation on World War II battlefields (2). HEPA filters did nothing to filter radiation particles, but researchers quickly learned that HEPA filters could filter out many harmful pollutants. In 1963, Manfred and Klaus Hammes, the founders of IQAir, introduced the world’s first residential air filter based on HEPA technology, helping reduce indoor pollution as well as chronic asthma symptoms. Not long after, HEPA became so widespread that the U.S. Department of Energy (DOE) required that all filters sold under the name “HEPA” must filter at least 99.97% of airborne particles down to 0.3 microns (3). Since then, HEPA air purification has become the standard for the air purification industry. HEPA is now thrown around as a generic term for air filters, but HEPA filters continue to filter 99.97% of particles down to 0.3 microns. The HyperHEPA filter builds upon the HEPA model to create even more efficient filtration systems. Many manufacturers, including IQAir, have built upon the HEPA model to create even more efficient filtration systems. IQAir’s patented HyperHEPAfilter is one such filter. HyperHEPA filters remove 99.5% of particles down to 0.003 microns, which are 100 times smaller than the DOE’s required 0.3-micron particle size. 2. Not all air purifier designs are created equal. All air purifier manufacturers know that their filters need to live up to this HEPA standard. But long-standing, strict guidelines around air filters can provide a false sense of security in HEPA. To advertise an air purifier as HEPA, it only needs to contain HEPA paper, the paper used to construct a HEPA filter. Whether the air purifier’s Total System Efficiency meets HEPA requirements is another story. In fact, most HEPA air purifiers are not tested for total efficiency (4). The hidden factor at work here is leakage. Despite the high efficiency of many HEPA filters, the housing designs of many air purifiers are not airtight. This means that dirty, unfiltered air passes around the HEPA filter through tiny openings, cracks, and space around the frame of the HEPA filter itself or between the frame and the purifier housing (5). So even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, they’re only telling part of the story. In some cases, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less (6). Even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less. Some air purifier manufacturers have resolved this issue with designs that are built to minimize or eliminate leakage. IQAir uses patented 3D UltraSeal knife-edge-in-groove sealing between the filter frame and the purifier housing to guarantee the full efficiency of our HyperHEPA filtration media. 3. Concerned about gas and odors? Go beyond HEPA. While HyperHEPA filters are great at getting particles out of the air, they do NOT take gases and odors out of the air. Unlike particles, the molecules that comprise gases, odors, and volatile organic compounds (VOCs) are not solid and will float through even the densest HyperHEPA filters. That’s where activated carbon filters come in. How do these filters work? It’s simpler than you might think: Chunks of carbon material (like charcoal) are exposed to high concentrations of oxygen. Countless pores open on the carbon surface, increasing the carbon surface area enormously. At this point, a pound of activated carbon can have the same surface area as 100 football fields. Several pounds of activated carbon are arranged in a flat “bed” and packaged in a proprietary filter design (such as IQAir’s V5 Cell gas and odor control filter). Air passes through the activated carbon bed. Gas, chemical, and VOC molecules are adsorbed into the carbon pores, meaning that they chemically bond to the extensive charcoal surface area. Activated carbon adsorption is the go-to method of filtration for gases as well as chemical pollutants from vehicle emissions and combustion processes (7)(8). Activated carbon adsorption is the go-to method of filtration for gases as well as chemical pollutants from vehicle emissions and combustion processes. Some air purifiers are designed to maximize activated carbon in case you’re more concerned about, for example, gases from cooking or odors from pets than about particle pollution in your home. IQAir’s GC MultiGas is built for such a purpose—while carbon filters generally use a few pounds of carbon, the GC MultiGas contains 12 pounds of activated carbon as well as impregnated alumina, providing well over 1200 football fields worth of surface area for gas and VOC molecules to adsorb to. The takeaway Now you know that the elements of a good air purifier are: HyperHEPA media for particle filtration No system leakage due to sealed filter and purifier housing Activated carbon for gas and odor filtration But we're not done yet. Just as important to know is what not to look for in an air purifier. What should I avoid in an air purifier? When considering air purifiers, some people wonder about their effectiveness and even potential risks. Question often arise, such as \"Do air purifiers work?\" or \"Are air purifiers effective?\" The answer is that while some air cleaning methods can remove particles and pollutants from the air, their capabilities are often limited. But it's not just about effectiveness. People also ask, \"Are air purifiers bad for you?\" This concern arises from potential hidden costs to your health. It's important to be aware of inefficiencies and any potential risks associated with the air purifier you're considering before making a purchase. So, if you're in the market for an air purifier, remember to ask yourself whether it will be effective at removing pollutants and particles from the air, and whether it poses any risks to your health. Ionizer air purifiers Ionizers are purported to purify air by sending out negatively charged ions (anions) that attract positively charged pollution particles (cations), causing them to leave the air and stick to surfaces like ceilings, walls, and furniture. Many popular air purifiers use ionization technology, also called negative ionization, as a central component of their operation. Research suggests that ionizers can help stop potentially infectious molds and bacteria from spreading in sterile environments like dental clinics and hospitals (9)(10). But there are two critical downsides to ionization (11)(12): Ionizer air purifiersdon’t get rid of pollutants. Particles charged by negative ions aren’t removed from the air—they merely stick to surfaces nearby. This includes surfaces inside your airways, such as your windpipe and alveoli, the sacs of air in your lungs. Pollutant build-up can cause heart, lung, and other respiratory conditions. Ionizer air purifierscan generate harmful ozone. Ionizers produce ozone (O3) that can build up to dangerous levels indoors. At even low levels, indoor ozone can irritate your airways, trigger asthma attacks, damage your olfactory bulb (the organ that helps your brain process odors), and even be fatal at high concentrations. Indoor ozone can irritate your airways, trigger asthma attacks, damage your olfactory bulb, and even be fatal at high concentrations. Verdict Don't buy an ionizer air purifier.They don’t remove particles from the air, and the ozone they produce can have harmful side effects, even if the purifier claims that they only charge the particles “a little bit.” Ozone Generators It’s worth saying again: ozone is TERRIBLE for you, especially indoor ozone build-up. The health concerns are serious enough that in 2017, California banned the use of ozonehome air purifiers (13). Ozone generators use a process called corona discharge to release ozone molecules into the air. When an ozone molecule intermingles with a particle or gas molecule, an ozone atom clings to the other molecule and blows it up in a process known as oxidation. Oxidation in the atmosphere after a lightning strike is also what makes the air smell so distinct after a thunderstorm. However, ozone generators do little to clean air and are quite bad for you. Here’s just a short (and far from complete) list of reasons why (14)(15)(16)(17)(18): Ozone can take years to fully clear even a small room of gases. Ozone reactions can introduce ultrafine particles (UFPs) into the air.UFPs can get into your lungs and your bloodstream, causing heart disease and even stunting lung development in children. Indoor ozone levels can rise five to ten times above recommended limits,which range from 0.05 to 0.1 parts per million (ppm), because of a lack of ventilation and in combination with outdoor ozone that seeps indoors.To put this in perspective, those who are sensitive to ozone, such as children, people with asthma, and pets, start experiencing health effects at only 0.01 ppm. Even a “safe” ozone generator that emits a small amount of ozone can quickly trigger potentially life-threatening ailments like asthma attacks. Verdict Don’t buy an ozone generator. They’re NOT air purifiers. Not only do they fail to clean your air, they hurt you and the most vulnerable in your home: your children and your pets. UV Light Purifiers Ultraviolet (UV) light is often used to disinfect equipment in hospitals and prevent the spread of harmful strains of bacteria and viruses (19)(20). One of the most common UV purification methods is called ultraviolet germicidal irradiation, or UVGI. In UVGI, intense UV lights are shined on bacteria and viruses, damaging their DNA beyond repair. Bacterial cells and viruses then shut themselves down because they can no longer function. This is called apoptosis, or programmed cell death, which effectively destroys their ability to cause infections (21). But UV air purification isn’t all it’s cracked up to be. Here’s why(22) (23) (24) (25) (26): Bacteria and viruses need to be exposed to UV light for a certain amount of timebefore they’re rendered harmless: some strains need to be treated with UV for several hours in direct UV light before they’re destroyed.Home UV air purifiers don’t shine UV light on them long enough to be genuinely useful. Some bacteria can come back to life and become infectious again even after being disinfected by UV light. UV lights do nothing for pollutant particles.Air treated with UV light can still be full of harmful particulate matter, like PM10 and PM2.5. Many UV air purifiers produce ozone. UV light can burn your skin and damage your eyes. Sure, most UV purifiers block the light from shining out of the purifier, but even brief UV exposure can cause permanent skin and eye damage as well as cancer. Air treated with UV light can still be full of harmful particulate matter. Verdict Don’t buy a UV light air purifier. UV light somewhat disinfects but doesn’t purify air, and research shows that UV’s disinfection potential for air may be exaggerated. What do I do now? At this point, you should feel like you have a good sense of what’s fact and what’s fiction when it comes to a truly effective air purification system. So, what should you do now, armed with your knowledge of what makes a good air purifier? You have a multitude of options for maximizing your indoor air quality: Get a HyperHEPA air purifier. Patented HyperHEPA filtration technology removes 99.5% of pollutant particles down to 0.003 microns, the smallest particles in existence. Use advanced gas-phase filtration. Patented V5 Cell gas and odor control filters, used in HealthPro Series air purifiers, eliminateharmful chemicals and compounds with five pounds of activated carbon. The GC MultiGas features 12 pounds of activated carbon and impregnated alumina to help protect you against indoor gases and chemicals, in addition to our powerful HyperHEPA particle filtration. Use a personal air purifier. Atem Series personal air purifiers are equipped with HyperHEPA filtration technology and a PureJet diffuser that instantly blankets you in clean air. They’re sleek, compact, and portable, allowing you to breathe virtually pure air anytime, anywhere. Install a whole-house air purifier.

HEPA filters did nothing to filter radiation particles, but researchers quickly learned that HEPA filters could filter out many harmful pollutants.

In 1963, Manfred and Klaus Hammes, the founders of IQAir, introduced the world’s first residential air filter based on HEPA technology, helping reduce indoor pollution as well as chronic asthma symptoms. Not long after, HEPA became so widespread that the U.S. Department of Energy (DOE) required that all filters sold under the name “HEPA” must filter at least 99.97% of airborne particles down to 0.3 microns (3).

Since then, HEPA air purification has become the standard for the air purification industry. HEPA is now thrown around as a generic term for air filters, but HEPA filters continue to filter 99.97% of particles down to 0.3 microns.

The HyperHEPA filter builds upon the HEPA model to create even more efficient filtration systems.

Many manufacturers, including IQAir, have built upon the HEPA model to create even more efficient filtration systems. IQAir’s patented HyperHEPAfilter is one such filter. HyperHEPA filters remove 99.5% of particles down to 0.003 microns, which are 100 times smaller than the DOE’s required 0.3-micron particle size.

2. Not all air purifier designs are created equal.

All air purifier manufacturers know that their filters need to live up to this HEPA standard. But long-standing, strict guidelines around air filters can provide a false sense of security in HEPA.

To advertise an air purifier as HEPA, it only needs to contain HEPA paper, the paper used to construct a HEPA filter. Whether the air purifier’s Total System Efficiency meets HEPA requirements is another story. In fact, most HEPA air purifiers are not tested for total efficiency (4).

The hidden factor at work here is leakage. Despite the high efficiency of many HEPA filters, the housing designs of many air purifiers are not airtight. This means that dirty, unfiltered air passes around the HEPA filter through tiny openings, cracks, and space around the frame of the HEPA filter itself or between the frame and the purifier housing (5).

So even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, they’re only telling part of the story. In some cases, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less (6).

Even though many air purifiers claim that their HEPA filters remove nearly 100% of particles from the air that passes through them, the actual efficiency of the whole air purifier design, with leakage considered, is closer to 80% or less.

Some air purifier manufacturers have resolved this issue with designs that are built to minimize or eliminate leakage. IQAir uses patented 3D UltraSeal knife-edge-in-groove sealing between the filter frame and the purifier housing to guarantee the full efficiency of our HyperHEPA filtration media.

3. Concerned about gas and odors? Go beyond HEPA.

While HyperHEPA filters are great at getting particles out of the air, they do NOT take gases and odors out of the air.

Unlike particles, the molecules that comprise gases, odors, and volatile organic compounds (VOCs) are not solid and will float through even the densest HyperHEPA filters. That’s where activated carbon filters come in.

How do these filters work? It’s simpler than you might think:

Chunks of carbon material (like charcoal) are exposed to high concentrations of oxygen.
Countless pores open on the carbon surface, increasing the carbon surface area enormously. At this point, a pound of activated carbon can have the same surface area as 100 football fields.
Several pounds of activated carbon are arranged in a flat “bed” and packaged in a proprietary filter design (such as IQAir’s V5 Cell gas and odor control filter).
Air passes through the activated carbon bed.
Gas, chemical, and VOC molecules are adsorbed into the carbon pores, meaning that they chemically bond to the extensive charcoal surface area.

Activated carbon adsorption is the go-to method of filtration for gases as well as chemical pollutants from vehicle emissions and combustion processes (7)(8).

Activated carbon adsorption is the go-to method of filtration for gases as well as chemical pollutants from vehicle emissions and combustion processes.

Some air purifiers are designed to maximize activated carbon in case you’re more concerned about, for example, gases from cooking or odors from pets than about particle pollution in your home. IQAir’s GC MultiGas is built for such a purpose—while carbon filters generally use a few pounds of carbon, the GC MultiGas contains 12 pounds of activated carbon as well as impregnated alumina, providing well over 1200 football fields worth of surface area for gas and VOC molecules to adsorb to.

The takeaway

Now you know that the elements of a good air purifier are:

\nHyperHEPA media for particle filtration
\nNo system leakage due to sealed filter and purifier housing
\nActivated carbon for gas and odor filtration

But we're not done yet. Just as important to know is what not to look for in an air purifier.

What should I avoid in an air purifier?

When considering air purifiers, some people wonder about their effectiveness and even potential risks. Question often arise, such as \"Do air purifiers work?\" or \"Are air purifiers effective?\" The answer is that while some air cleaning methods can remove particles and pollutants from the air, their capabilities are often limited.

But it's not just about effectiveness. People also ask, \"Are air purifiers bad for you?\" This concern arises from potential hidden costs to your health. It's important to be aware of inefficiencies and any potential risks associated with the air purifier you're considering before making a purchase.

So, if you're in the market for an air purifier, remember to ask yourself whether it will be effective at removing pollutants and particles from the air, and whether it poses any risks to your health.

Ionizer air purifiers

Ionizers are purported to purify air by sending out negatively charged ions (anions) that attract positively charged pollution particles (cations), causing them to leave the air and stick to surfaces like ceilings, walls, and furniture.

Many popular air purifiers use ionization technology, also called negative ionization, as a central component of their operation. Research suggests that ionizers can help stop potentially infectious molds and bacteria from spreading in sterile environments like dental clinics and hospitals (9)(10).

But there are two critical downsides to ionization (11)(12):

\nIonizer air purifiersdon’t get rid of pollutants. Particles charged by negative ions aren’t removed from the air—they merely stick to surfaces nearby. This includes surfaces inside your airways, such as your windpipe and alveoli, the sacs of air in your lungs. Pollutant build-up can cause heart, lung, and other respiratory conditions.
\nIonizer air purifierscan generate harmful ozone. Ionizers produce ozone (O3) that can build up to dangerous levels indoors. At even low levels, indoor ozone can irritate your airways, trigger asthma attacks, damage your olfactory bulb (the organ that helps your brain process odors), and even be fatal at high concentrations. \n

Indoor ozone can irritate your airways, trigger asthma attacks, damage your olfactory bulb, and even be fatal at high concentrations.

Verdict

Don't buy an ionizer air purifier.They don’t remove particles from the air, and the ozone they produce can have harmful side effects, even if the purifier claims that they only charge the particles “a little bit.”

Ozone Generators

It’s worth saying again: ozone is TERRIBLE for you, especially indoor ozone build-up. The health concerns are serious enough that in 2017, California banned the use of ozonehome air purifiers (13).

Ozone generators use a process called corona discharge to release ozone molecules into the air. When an ozone molecule intermingles with a particle or gas molecule, an ozone atom clings to the other molecule and blows it up in a process known as oxidation. Oxidation in the atmosphere after a lightning strike is also what makes the air smell so distinct after a thunderstorm.

However, ozone generators do little to clean air and are quite bad for you. Here’s just a short (and far from complete) list of reasons why (14)(15)(16)(17)(18):

\nOzone can take years to fully clear even a small room of gases.
\nOzone reactions can introduce ultrafine particles (UFPs) into the air.UFPs can get into your lungs and your bloodstream, causing heart disease and even stunting lung development in children.
\nIndoor ozone levels can rise five to ten times above recommended limits,which range from 0.05 to 0.1 parts per million (ppm), because of a lack of ventilation and in combination with outdoor ozone that seeps indoors.To put this in perspective, those who are sensitive to ozone, such as children, people with asthma, and pets, start experiencing health effects at only 0.01 ppm. Even a “safe” ozone generator that emits a small amount of ozone can quickly trigger potentially life-threatening ailments like asthma attacks.

Verdict

Don’t buy an ozone generator. They’re NOT air purifiers. Not only do they fail to clean your air, they hurt you and the most vulnerable in your home: your children and your pets.

UV Light Purifiers

Ultraviolet (UV) light is often used to disinfect equipment in hospitals and prevent the spread of harmful strains of bacteria and viruses (19)(20).

One of the most common UV purification methods is called ultraviolet germicidal irradiation, or UVGI.

In UVGI, intense UV lights are shined on bacteria and viruses, damaging their DNA beyond repair. Bacterial cells and viruses then shut themselves down because they can no longer function. This is called apoptosis, or programmed cell death, which effectively destroys their ability to cause infections (21).

But UV air purification isn’t all it’s cracked up to be. Here’s why(22) (23) (24) (25) (26):

\nBacteria and viruses need to be exposed to UV light for a certain amount of timebefore they’re rendered harmless: some strains need to be treated with UV for several hours in direct UV light before they’re destroyed.Home UV air purifiers don’t shine UV light on them long enough to be genuinely useful.
\nSome bacteria can come back to life and become infectious again even after being disinfected by UV light.
\nUV lights do nothing for pollutant particles.Air treated with UV light can still be full of harmful particulate matter, like PM10 and PM2.5.
Many UV air purifiers produce ozone.
\nUV light can burn your skin and damage your eyes. Sure, most UV purifiers block the light from shining out of the purifier, but even brief UV exposure can cause permanent skin and eye damage as well as cancer.

Air treated with UV light can still be full of harmful particulate matter.

Verdict

Don’t buy a UV light air purifier. UV light somewhat disinfects but doesn’t purify air, and research shows that UV’s disinfection potential for air may be exaggerated.

But there are steps you can take to prepare yourself using appropriate safety precautions for wildfires. Keep the air clean in your home. Keep windows and doors closed closed and seal off any openings to the outside, including vents, to help prevent outdoor smoke from getting in. When using an air conditioner, be sure to set it to re-circulate and close the fresh-air intake. Filter the air when ventilating the space.

This is critical if you live in an urban area downwind (even remotely) from wildfires. Stay indoors as much as possible. This tactic is most useful in buildings that effectively stop outdoor air from getting inside. If you need to travel by car to leave or evacuate an area affected by wildfire smoke, use a car air purifier to help keep your vehicle interior air clean as you pass through smoky or polluted areas. You can also use a portable, personal air purifier to access clean air where other air filtration systems are not available. Wear a mask outdoors. Only use an air pollution mask with an N95, KN95, N100, or FFP2 rating to help. Avoid activities that further pollute the indoor air. Avoid burning candles, using the fireplace, or even vacuuming unless you own a high-performance HEPA vacuum cleaner. All of these activities can otherwise become additional sources of indoor air pollutants. Monitor your indoor air quality. Use an air quality monitor to track levels of indoor pollutants like PM2.5 and CO2 from smoke and other indoor pollution sources. Take action if indoor air pollutants rise to dangerous levels by running an air purifier, circulating fresh air through your HVAC system, or leaving your home temporarily if indoor air becomes unsafe to breathe or your home is threatened by wildfire. Use an air quality monitoring app to keep track of pollutants in your environment. The AirVisual app displays real-time hyperlocal data from over 80,000 sensors around the world.

Get to know the science behind air cleaning technology, and how a high-performance air purifier can capture PM2.5.

","Yes, air purifiers can significantly reduce indoor PM2.5 levels. Studies have shown that high-efficiency filtration can lower concentrations of fine particulate matter indoors (1). What is PM2.5? PM2.5 refers to fine airborne particles measuring 2.5 microns or smaller—small enough to penetrate deep into the lungs and even enter the bloodstream. These particles come from sources like vehicle emissions, wildfire smoke, industrial pollution, and cooking. Air purifiers with high-efficiency filtration, particularly HyperHEPA filtration, are designed to capture and remove PM2.5, improving indoor air quality and reducing health risks associated with long-term exposure, such as respiratory issues, cardiovascular disease, and aggravated allergies or asthma. How PM2.5 builds up indoors PM2.5 does not need to originate indoors to affect indoor air quality. Fine particles from outdoor pollution can enter through doors, windows, ventilation systems, and small gaps in buildings. Indoor activities such as cooking, candles, smoking, and cleaning can also generate PM2.5. Because these particles are extremely small and lightweight, they can remain suspended in the air and continue circulating long after they are produced. How air purifiers reduce indoor PM2.5 Air purifiers combat PM2.5 using advanced filtration technologies. The primary filtration layer is typically a HEPA filter, which physically traps fine particles as air passes through. HyperHEPA filters are even more effective, capturing ultrafine particles down to 0.003 microns—far smaller than PM2.5—with an efficiency of at least 99.5%. This makes them effective at reducing not just PM2.5, but also ultrafine particles from sources like wildfires or vehicle exhaust. Many air purifiers also include a pre-filter to capture larger particles, extending the life of the main filter, and an activated carbon filter to address gases and odors that often accompany PM2.5 pollution. Smart purifiers with real-time air quality sensors can automatically adjust fan speeds to respond to spikes in PM2.5, helping respond to changing indoor conditions during high-pollution events like wildfires or heavy traffic periods. The health impact of reducing indoor PM2.5 Long-term exposure to PM2.5 has been linked to respiratory disease, cardiovascular disease, and other chronic health conditions. By lowering indoor PM2.5 levels, air purifiers help mitigate these risks, especially for vulnerable groups like children, the elderly, and those with pre-existing conditions. For maximum protection, place the purifier in rooms where you spend the most time, such as bedrooms or living areas, and run it continuously. Sealing windows and doors during high-pollution events further enhances the purifier’s effectiveness by preventing outdoor PM2.5 from entering your home. Frequently Asked Questions Can an air purifier remove all PM2.5 from indoor air?While no purifier can eliminate 100% of PM2.5, models with HyperHEPA filtration capture up to 99.5% of PM2.5 and can significantly improve indoor air quality. How quickly can an air purifier lower PM2.5 levels?Most purifiers begin reducing PM2.5 within minutes, but it may take a few hours to achieve maximum reduction, depending on room size, purifier strength, and initial pollution levels. Should I run my air purifier 24/7 to combat PM2.5?Yes. Continuous operation ensures PM2.5 levels stay low, especially in high-pollution areas or during events like wildfires. Use auto mode to balance energy use and purification. Can air purifiers help with wildfire smoke?Yes. Wildfire smoke is rich in PM2.5, and HyperHEPA air purifiers are effective at removing these particles. Close windows and run the purifier on high during smoke events for best results. Conclusion PM2.5 does not need to originate indoors to affect indoor air quality.

Environmental changes and pollution don’t affect everyone in the same way. Learn why marginalized groups are heavily affected by climate injustice and the pathways to a new future.

","Communities that contribute the least to global emissions are often the most affected by poor air quality and environmental change (1). Often referred to as climate justice—the idea that environmental impacts are not experienced equally—this imbalance is shaped by differences in infrastructure, policy, economic resources, and proximity to pollution sources. From power generation to urban pollution, hidden environmental injustices affect the long-term health and well-being of underrepresented communities. As these systemic inequalities become more visible, pathways to a cleaner, healthier future are emerging. The unequal burden of pollution Global patterns of unequal exposure According to the World Health Organization (WHO), 99% of the world’s population breathes polluted air, increasing health risks. Marginalized communities face the greatest disparities, as 97% of cities in low- and middle-income countries fail to meet WHO air quality standards, compared to 49% of high-income countries (2)(3). These disparities are not random—they reflect structural differences in development, regulation, and access to resources. Urban environments and heat In Delhi, India, a lower-middle-income country, the dense population combined with an abundance of city emissions and lack of environmental policies have created an overwhelming amount of heat, also known as an Urban Heat Island (4). Surrounded by concrete buildings and cement, heat gets easily trapped within cityscapes and continues to build over time as fuel emissions are burned. Increased temperatures from pollution can manifest into unhealthy air quality environments for individuals, with elevated levels of volatile organic chemicals (VOCs) and faster dispersion of pollutant particles (5). This means that lower-income communities—often living in denser areas with less access to cooling, green space, or protective infrastructure—can experience the most intense effects of both heat and pollution. Local impacts in the United States In the United States, similar patterns can be observed at a local level. In some regions, communities are located in close proximity to industrial corridors, where long-term exposure to emissions is part of daily life. One example is an industrial stretch along the Mississippi River in Louisiana, often referred to as “Cancer Alley,” where residents live near petrochemical facilities and manufacturing plants, also known as fenceline communities (6). Pollutant emissions can leach into water supplies and settle on surfaces, leaving residents to breathe and consume contaminants over extended periods. Parts of this region have been associated with some of the highest estimated cancer risks from industrial air emissions in the United States (7). In this way, the burden of pollution is shaped not just by geography, but by how communities are positioned in relation to industrial activity—and the resources available to respond. Environmental change and ecosystem pressure In the Amazon Rainforest, South America, ongoing deforestation has caused a decrease in rainfall and natural plant resources (8). Deforestation disrupts natural plant cycles, leading to greater climate change and impacting indigenous communities. As trees from the rainforest are harvested, fossil fuels burn from cutting machinery and less plant material is present to consume the excess carbon dioxide, elevating air pollutant levels altogether. Long-term exposure to air pollutants can lead to chronic health complications including heart disease, lung cancer, and respiratory issues. Health complications can affect marginalized communities in disproportionate ways, as it can be more difficult for individuals in these spaces to access affordable medicine or relocate themselves away from pollution (9). These patterns show how air pollution is not only an environmental issue, but also a question of equity—shaped by where people live and the resources available to respond. Exposing hidden inequalities Addressing these disparities often begins with making them visible. Monitoring air quality and environmental conditions is key to shining a new light on hidden climate injustices happening from around the globe to a person’s own backyard. Global initiatives, such as Schools4Earth, encourage active air quality monitoring while promoting early education and climate advocacy. Schools4Earth works to place air quality monitors in schools worldwide to motivate students to be environmentally conscious and teach safe monitoring practices. In Yaoundé, the capital of Cameroon, the Franky Comprehensive Secondary School hosts the country’s first campus-based air quality monitor as part of the Schools4Earth initiative. Cameroon’s air quality data is limited, and by installing a monitor in 2026, the country allows for increased awareness on changing air climate conditions. The air quality monitor is a beacon for both environmental education for students and real-time air pollution surveillance for public safety. In conjunction with global initiatives, community-led programs are paving a new path for these environmental inequalities to be addressed and surveyed. In Milwaukee, Wisconsin, locals noticed heavy concentrations of industrial and vehicle pollutants present in differing neighborhoods within the city during early 2024. Due to long-term exposure, residents in the region experienced asthma attacks and worsening health conditions. To address the elevated levels of pollutants, residents installed air quality monitors around various areas scattered across the city, allowing locals to survey daily air conditions and address real-time pollution warnings. In Nairobi, the capital of Kenya, community members have been struggling with long-term air pollution and fuel emissions for years. Compared to high-income countries, Kenya had very limited air quality data, leaving residents defenseless to unknown levels of pollution and toxins. To address this data gap, community members installed an air quality monitor with a Monster Aerosol System and Time-of-Flight Aerosol Chemical Speciation Monitor. This technology provides real-time, high-resolution data on airborne particles—including nitrates, ammonium, and chlorides—revealing the chemical fingerprints of pollution. Pathways to cleaner air for all Through global and community-led programs, environmental issues are becoming more visible—and in some cases, are beginning to shape policy responses. In 2024, the U.S. Environmental Protection Agency strengthened National Ambient Air Quality Standards for Particulate Matter, lowering the rate from 12 to 9 micrograms per cubic meter (10). The updated standard requires significantly lower concentrations of airborne particles for air to be considered safe. In 2019, Europe introduced the European Green Deal, an initiative aimed to reduce fuel emissions and achieve complete carbon neutrality by 2050 (11). Improving air quality at scale requires coordinated action across individuals, communities, and governments (12), including: Individual Actions: Support clean air initiatives, reduce personal pollutant emissions, and amplify marginalized voices Community Actions: Install air quality monitors around neighborhoods, create community-led initiatives, and petition in local areas for environmental security Government Actions: Enforce stricter fuel emission standards, invest in environmentally sustainable infrastructure, and promote nationwide clean air programs Addressing these disparities depends on how effectively these efforts are aligned—ensuring that the burden of pollution is reduced, not redistributed. Conclusion Air pollution and climate change are closely linked, but their impacts are not evenly distributed. Across regions and communities, exposure is shaped by infrastructure, policy, and access to resources. Despite contributing the least to global emissions, many low-income communities face the highest levels of pollution with the fewest resources to respond. Observed each year on June 5, World Environment Day highlights how improving air quality is part of broader environmental efforts—and a meaningful step toward more equitable outcomes.","

The unequal burden of pollution

Global patterns of unequal exposure

According to the World Health Organization (WHO), 99% of the world’s population breathes polluted air, increasing health risks. Marginalized communities face the greatest disparities, as 97% of cities in low- and middle-income countries fail to meet WHO air quality standards, compared to 49% of high-income countries (2)(3).

In 2024, the U.S. Environmental Protection Agency strengthened National Ambient Air Quality Standards for Particulate Matter, lowering the rate from 12 to 9 micrograms per cubic meter (10). The updated standard requires significantly lower concentrations of airborne particles for air to be considered safe. In 2019, Europe introduced the European Green Deal, an initiative aimed to reduce fuel emissions and achieve complete carbon neutrality by 2050 (11).

Improving air quality at scale requires coordinated action across individuals, communities, and governments (12), including:

Individual Actions: Support clean air initiatives, reduce personal pollutant emissions, and amplify marginalized voices
\n
Community Actions: Install air quality monitors around neighborhoods, create community-led initiatives, and petition in local areas for environmental security
\n
Government Actions: Enforce stricter fuel emission standards, invest in environmentally sustainable infrastructure, and promote nationwide clean air programs
\n

Addressing these disparities depends on how effectively these efforts are aligned—ensuring that the burden of pollution is reduced, not redistributed.

Conclusion

Air pollution and climate change are closely linked, but their impacts are not evenly distributed. Across regions and communities, exposure is shaped by infrastructure, policy, and access to resources.

Despite contributing the least to global emissions, many low-income communities face the highest levels of pollution with the fewest resources to respond.

Observed each year on June 5, World Environment Day highlights how improving air quality is part of broader environmental efforts—and a meaningful step toward more equitable outcomes.

But clean air is now even more critical for buildings seeking to help protect occupants as they resume onsite operations following the COVID-19 pandemic and face the ongoing health and productivity challenges of indoor air pollution in the office environment. Global air pollution, especially PM2.5, remains a major threat to health. In 2022, air pollution accounted for six million deaths and had an estimated economic cost of $8 trillion dollars. In 2022, air pollution accounted for six million deaths and had an estimated economic cost of $8 trillion dollars. High-efficiency air filtration in the workplace has become more than just a workplace benefit – it’s a competitive advantage in attracting and retaining high-performing employees concerned about their health and safety in shared facilities. High-efficiency air filtration is a competitive advantage in attracting and retaining high-performing employees concerned about their health and safety in shared facilities. A facility can pose unique air quality challenges that might make air filtration difficult and costly to implement as public health guidelines and air quality problems change. With the Clean Air Facility program, air quality experts design customized air filtration solutions for your facility, leveraging HVAC systems and stand-alone filtration to improve indoor air quality in your entire facility. How to become a Clean Air Facility To become a designated Clean Air Facility, the following process is used to identify and implement clean air solutions while demonstrating the long-term benefits of clean air: on-site air quality assessment air quality verification and monitoring publish your facility’s air quality in Clean Air Facility directory (optional) maintenance and renewal of Clean Air Facility status On-site air quality assessment First, a thorough air quality assessment (either onsite or virtual) is performed to discern the exact air quality solutions your building will need to meet Clean Air Facility requirements. The following factors are considered as Clean Air Facility staff assess a building’s needs. Local air pollution sources Localized air pollution sources and air pollution concentrations over time can vary dramatically from building to building based on location and operating hours. For example, office buildings near busy streets or highways may experience their highest levels of air pollution during morning and afternoon vehicle traffic. Vehicle exhaust is a major source of PM2.5, ultrafine particles (UFPs), chemicals, and volatile organic compounds (VOCs).1,2 Air filtration must be designed not only to help reduce outdoor air pollution that can seep indoors but also remove indoor air pollutants from furnishings, construction materials, and personal hygiene products that can impact employee health and productivity. Building age and existing HVAC design The average commercial building in the United States is 53 years old, with only 12 percent of buildings built after 2003 and the majority built before 1946.3,4,5 The average commercial building in the United States is 53 years old, with only 12 percent of buildings built after 2003 and the majority built before 1946. Despite the age of a building, our Solutions Engineers can design filtration solutions that can be retrofitted into existing heating, ventilation, and air conditioning (HVAC) systems or customize stand-alone solutions for any facility. Expert consultation Evaluations (onsite or virtual) by subject matter experts in commercial air quality and air filtration systems can help simplify this process through the following steps: Building walkthrough: Facility construction, HVAC systems, and existing air filtration (if applicable) are documented. Spot measurements of ambient air quality: Major sources of air pollution, both indoors and outdoors, are documented using high-accuracy air quality monitoring tools. Inspection of air handlers and air distribution: Current facility HVAC and air filtration technology, including outstanding maintenance and upgrades, are noted. Detailed analysis: A written report is shared with facility stakeholders, describing air quality issues and suggesting customized air filtration solutions to help the building meet Clean Air Facility requirements. Based on evaluation results, one or more of the following solutions may be proposed: HVAC air filtration: For many buildings, HVAC air filtration is the most logical choice for air pollution mitigation. This type of air quality solution uses centralized airflow and filtration mechanisms to help deliver clean air to the entire building through facility ductwork. Localized air filtration solutions: Stand-alone air purifiers or room air purifiers can provide clean air to workspaces that may not have access to a centralized HVAC system or may be required depending on the day to day activities that take place within the facility. A high-performance system can provide several air changes per hour (ACH) and filter up to 99.5% of airborne particles in any given workspace. Individualized air purification: Personal air purifiers can help shield employees at individual workstations from air pollutants and airborne infections, delivering clean air filtered from up to 99% of airborne particles directly to a person’s breathing zone. Many buildings have traditionally relied on HVAC air filters rated MERV 13 or lower according to the MERV efficiency system based on the ASHRAE 52.2 standard.6 However, MERV 13 is tested to capture up to 50% of airborne particles ranging from 0.3-1.0 microns in size. This can leave up to half of the most dangerous airborne particles unfiltered, including airborne infections and ultrafine particles (UFPs). MERV 13 filters also require extensive mechanical ventilation to effectively dilute indoor concentrations of airborne particles. This can negatively affect a building in two ways: increased penetration of outdoor air can reduce building energy efficiency by disrupting indoor climate control and requiring increased HVAC operation hours for thermal comfort ventilation with outdoor air can bring in outdoor air pollutants that can cause poor indoor air quality, reducing the efficiency of air filtration systems IQAir filtration technology provides high-efficiency HVAC panel filters with ultralow pressure drop. In fact, NanoMax filtration technology exceeds MERV 16 standards with only the pressure drop of an average MERV 8 filter. NanoMax filters are suggested as an alternative to counter these potential downsides of traditional MERV 13 air filters. NanoMax filters are tested to capture up to 96 percent of airborne particles between 0.3-1.0 microns and at least 90% of UFPs less than 0.1 microns.7 Their high efficiency eliminates the need for additional mechanical ventilation beyond building code requirements. The high efficiency of NanoMax filters reduces the need for additional mechanical ventilation beyond building code requirements. Refer to the table below for a side-by-side comparison of filtration efficiencies for MERV 13 air filters and NanoMax air filters. Microns MERV 13 NanoMax Estimated Improvement with NanoMax 3-10 microns up to 90% up to 100% ~11% 1-3 microns 80-85% up to 99% Up to 24% 0.3-1 micron ≤ 50% up to 96% Up to 174% < 0.1 micron Not tested 90% Substantial Fewer HVAC filter changes NanoMax filters require fewer filter replacements over time. This can significantly reduce the costs associated with filter purchases and labor involved in filter replacements. Refer to the table below for an example of cost savings with NanoMax in comparison to MERV 13 filters for a facility using 50 NanoMax filters. Filter Type Filter Replacement Intervals * Yearly Maintenance Hours (15 min./filter) Yearly Filter Costs MERV 13 4 times per year 50 hours $2,000-$8,000 NanoMax (exceed MERV 16 performance) 1 time per year 12.5 hours $5,000 * based on 8 hours of HVAC operation per day (2,920 hours). Energy management Unlike many traditional MERV 13 air filtration systems, NanoMax HVAC air filters used as part of the Clean Air Facility program do not require additional mechanical ventilation beyond what is required per building code. As a result, buildings can only operate HVAC air filtration systems as needed to reduce energy usage. This helps minimize a building’s carbon footprint while maintaining 90 to 100 percent air filtration efficiency for particles while the building is occupied and HVAC systems are operating. Air quality monitoring and smart technology Smart indoor climate systems and other building control systems can also be paired with indoor and outdoor air quality monitoring to automate HVAC air filtration systems using preset protocols: HVAC Systems: Program smart thermostats to maintain energy-efficient “Fan On” mode and deliver clean air even in the absence of heating or cooling operations. High-Capacity Stand-Alone Systems: Pair air purifiers with occupancy sensors, timers, or air quality monitors so that systems operate when indoor spaces are occupied or indoor air pollution concentrations surpass pre-programmed thresholds. Air quality verification and monitoring The impact of PM2.5 and indoor gases like carbon dioxide (CO2) on employee health, productivity, and cognitive performance has long been documented.8,9,10,11 Air quality monitoring can provide crucial data to help ensure that HVAC systems supplies sufficient levels of clean and oxygenated air to occupants and reduce the health impacts of air pollution and airborne infections. You will receive an air quality report every month for your facility. You will be contacted within 4 business hours if there is an issue with your facility’s air quality. Public air quality data displays can also demonstrate to building inhabitants the immediate benefits of indoor clean air, especially when outdoor air pollution is heavy. This data can be displayed on publicly visible TV monitors or on company websites using customizable air quality data widgets (see Figure 1 for an example).

Clean air has extensive benefits, such as improving productivity and reducing absences due to sick building syndrome (SBS).

But clean air is now even more critical for buildings seeking to help protect occupants as they resume onsite operations following the COVID-19 pandemic and face the ongoing health and productivity challenges of indoor air pollution in the office environment.

Global air pollution, especially PM2.5, remains a major threat to health. In 2022, air pollution accounted for six million deaths and had an estimated economic cost of $8 trillion dollars.

How to become a Clean Air Facility

To become a designated Clean Air Facility, the following process is used to identify and implement clean air solutions while demonstrating the long-term benefits of clean air:

on-site air quality assessment
air quality verification and monitoring
publish your facility’s air quality in Clean Air Facility directory (optional)
maintenance and renewal of Clean Air Facility status

On-site air quality assessment

First, a thorough air quality assessment (either onsite or virtual) is performed to discern the exact air quality solutions your building will need to meet Clean Air Facility requirements.

The following factors are considered as Clean Air Facility staff assess a building’s needs.

Local air pollution sources

Localized air pollution sources and air pollution concentrations over time can vary dramatically from building to building based on location and operating hours.

For example, office buildings near busy streets or highways may experience their highest levels of air pollution during morning and afternoon vehicle traffic. Vehicle exhaust is a major source of PM2.5, ultrafine particles (UFPs), chemicals, and volatile organic compounds (VOCs).^1,2

Air filtration must be designed not only to help reduce outdoor air pollution that can seep indoors but also remove indoor air pollutants from furnishings, construction materials, and personal hygiene products that can impact employee health and productivity.

Building age and existing HVAC design

The average commercial building in the United States is 53 years old, with only 12 percent of buildings built after 2003 and the majority built before 1946.^3,4,5

The average commercial building in the United States is 53 years old, with only 12 percent of buildings built after 2003 and the majority built before 1946.

Despite the age of a building, our Solutions Engineers can design filtration solutions that can be retrofitted into existing heating, ventilation, and air conditioning (HVAC) systems or customize stand-alone solutions for any facility.

Expert consultation

Evaluations (onsite or virtual) by subject matter experts in commercial air quality and air filtration systems can help simplify this process through the following steps:

\nBuilding walkthrough: Facility construction, HVAC systems, and existing air filtration (if applicable) are documented.
\nSpot measurements of ambient air quality: Major sources of air pollution, both indoors and outdoors, are documented using high-accuracy air quality monitoring tools.
\nInspection of air handlers and air distribution: Current facility HVAC and air filtration technology, including outstanding maintenance and upgrades, are noted.
\nDetailed analysis: A written report is shared with facility stakeholders, describing air quality issues and suggesting customized air filtration solutions to help the building meet Clean Air Facility requirements.

Based on evaluation results, one or more of the following solutions may be proposed:

\nHVAC air filtration: For many buildings, HVAC air filtration is the most logical choice for air pollution mitigation. This type of air quality solution uses centralized airflow and filtration mechanisms to help deliver clean air to the entire building through facility ductwork.
\nLocalized air filtration solutions: Stand-alone air purifiers or room air purifiers can provide clean air to workspaces that may not have access to a centralized HVAC system or may be required depending on the day to day activities that take place within the facility. A high-performance system can provide several air changes per hour (ACH) and filter up to 99.5% of airborne particles in any given workspace.
\nIndividualized air purification: Personal air purifiers can help shield employees at individual workstations from air pollutants and airborne infections, delivering clean air filtered from up to 99% of airborne particles directly to a person’s breathing zone.

And when the holiday season comes around, special circumstances arise. When prepping homes, most consider only the cleanliness of surfaces like tabletops, counters, or floors, ensuring they are free of dust, dirt, and grime. Read on for 7 essential tips for handling holiday housecleaning and indoor air quality challenges. 1. Be mindful of entries and departures—guests bring more than food and presents. Like it or not, with the arrival of guests comes the arrival of dirt and dust. Household dust includes airborne particles blown in from outdoors, dead skin cells and hair from people and pets, dust mite bodies and droppings, tracked-in soil, and pollen (1). So, during the holidays, when opening doors for guests’ entrances and exits, dust comes in with the wind. Also, sources of dust cross the threshold on guests’ shoes and clothing. And since every guest has skin and hair, this tool adds to the dusty buildup. Solutions: To reduce dust, start by placing mats in front of every door. Encourage guests to remove their shoes at the door. Not only will guests be more comfortable, but your home will stay cleaner for your guests as well. If the air is polluted outdoors, don’t open the door for guests until all goodbyes have been said. Hanging around with the door wide open invites more contaminants into your home. 2. More time indoors, more indoor air pollutants. Dust With chillier outdoor temperatures, we, along with our guests and our pets, tend to be indoors more, shedding skin cells and hair. This is why household dust tends to increase during the holidays. Plus, our heaters are operating more often. Radiant heating systems don’t make much of mess in your house, but central, forced-air systems can add to the dust in the air and on surfaces. Wood stoves, which can certainly warm us up, not only create dust and ash, but the smoke from them can produce buildups of soot on surfaces. The common cold, flu and other viruses Keep in mind, the quality of your indoor air can also affect whether you or your guests contract and spread cold, the flu and other viruses. And while there is no cure for a cold, research does show that once you have a cold, the quality of the air you breathe has a significant effect on the severity of your symptoms. As you gear up for your holiday festivities, here are a few things you can do to deal with the increased time indoors and make sure your air is a clean as possible (2): Replace or clean your HVAC air filters regularly (at least every 3 months but more often if needed). Use portable electric heaters where reasonable. Use wood stoves that include a HEPA filter. Consider acquiring a whole-house air purifier system that works with your HVAC system to ensure every room has clean indoor air quality. 3. Fireplace: not be such a hot idea. Fireplaces, even fully gas-burning models, can significantly increase the number of airborne contaminants in your home. Firewood smoke in particular has been linked to strokes, heart disease, and lung cancer (3) (4). And like a wood stove, firewood smoke can stain household surfaces. Wood-burning fireplaces also create dust and ash that not only make a mess, they can also irritate airways and exacerbate asthma and allergy symptoms. Solutions The best way to prevent a fireplace from sullying your house and harming your indoor air quality and the health of you and your loved ones is to not use it. But if that is not practical: Use an air purifier in the room where the fireplace is For wood-burning fireplaces (5): Use wood, preferably hardwood, that was split, dried, and covered for at least six months. Install heat-proof glass doors. Regularly clean your fireplace’s interior to remove the dust and ash, while wearing a high-quality protective face mask to avoid breathing in these harmful particles. Make sure your air purifier is specifically designed to remove smoke and odors from the air. 4. Avoid burning candles, scented or not. Lighted candles are a common way to enhance the atmosphere during special holiday gatherings, but they create housecleaning issues much like a fireplace, and can add volatile organic compounds (VOCs) and ultrafine particles to your air. Scented candles, which usually use synthetic fragrances and dyes, can emit VOCs even when they are not lit (6). Solutions Use unscented candles to enhance your décor; maintain clean indoor air quality by not lighting them. To fill your house with wonderful holiday scents without adding contaminants to the air: Simmer fragrant spices like cinnamon sticks, cloves, and nutmeg in a pot of water. Diffuse essential oils (try to avoid fragrance oils that contain artificial ingredients). Place containers of potpourri around your home. 5. Prevent mold and pollen buildup. Planning on buying a holiday tree from a tree lot? You might want to reconsider. Besides the clutter from falling needles, these trees can add mold and pollen to household surfaces and produce indoor air quality that is inhospitable to those with allergies and asthma. After the trees are cut, they are tightly bundled, creating an environment for the growth of up to 50 types of mold, which have been found to increase the typical presence of mold spores in indoor air by more than six times in less than two weeks (7) (8). The trees can also be a source of pollen, which, besides being another allergen and asthma trigger, is an ingredient in dust. Paradoxically, it is not the tree’s own pollen grains but grains like ragweed pollen that settled on the tree and grass pollen that got stuck to the tree’s sap and is released when the sap dries out. Solutions To prevent Christmas trees from adding to an untidy home and unhealthy air: Use a reusable, artificial tree If you do buy a tree from a lot: Consider placing the tree outdoors within view from inside If that is not feasible: Clean and wipe the trunk of your tree thoroughly with water and bleach before you bring it into the house. Use a leaf blower to remove as many pollen grains as possible before bringing the tree indoors. Put the tree up later and get rid of it sooner. Cut the tree yourself, bypassing the storage and transportation conditions that promote mold growth. Use a high-performance room air purifier in the same room as the tree to help create good indoor air quality. 6. Cook with care. Who doesn’t love a holiday feast? But be careful—with increased cooking activities comes more grease and smoke stains. And gas stoves can add dangerous particulates to the air, such as nitrogen dioxide, which has been linked to asthma in children (9). Solutions Use ventilation fans when you cook. If you have a gas oven and stove, use electric cooking appliances such as a small oven or microwave when possible, instead. Use a personal air purifier when cooking to ensure your personal breathing zone is safe. 7. Use smart cleaning techniques before, during, and after the festivities. The additional housecleaning chores caused by the increased activities and visitors around the holiday season can also harm indoor air quality. So it’s important to focus on methods of cleaning that actually clean your home’s surfaces while sparing the air around you and your guests. For instance, many cleaning solvents release harmful chemicals into the air, including ammonia, chlorine, perchloroethylene or “perc,” 2-butoxyethanol and sodium hydroxide, better known as lye (10). Try to avoid cleaning products that include these and use sparingly if they can’t be avoided. Also, take care when purchasing cleaning products labeled “green” or “natural” as they too can contain ingredients that are harmful to your health (11). You can always refer to the comprehensive “Safer Choice” list provided by the U.S. Environmental Protection Agency, which includes cleaning products for home and vehicles (12). Finally, avoid improper dusting techniques that kick up and add more airborne dust to your breathing space that irritates eyes and airways and must be cleaned again once it settles. Solutions Use warm water and mild soap as a general household cleaning product. Instead of abrasive cleaners for scrubbing, use baking soda. For windows and other glass surfaces, use a mixture of vinegar and water. Avoid “dry-dusting,” and instead use a rag dampened with water. Rather than sweeping floors, which kicks up dust, use a vacuum with a HEPA filter that traps dust and dirt particles preventing them from returning to the air. Use a vacuum with a dusting attachment for items that are hard to dust like lampshades and drapes. Conclusion Maintaining a clean and healthy home, including good indoor air quality, might take a little extra work during the holidays. But in between the chores, you and your loved ones will better enjoy the festivities. A cleaner home means a healthier home, and after all, healthier holidays are happier holidays.","

For instance, many cleaning solvents release harmful chemicals into the air, including ammonia, chlorine, perchloroethylene or “perc,” 2-butoxyethanol and sodium hydroxide, better known as lye (10). Try to avoid cleaning products that include these and use sparingly if they can’t be avoided.

Also, take care when purchasing cleaning products labeled “green” or “natural” as they too can contain ingredients that are harmful to your health (11). You can always refer to the comprehensive “Safer Choice” list provided by the U.S. Environmental Protection Agency, which includes cleaning products for home and vehicles (12).

Finally, avoid improper dusting techniques that kick up and add more airborne dust to your breathing space that irritates eyes and airways and must be cleaned again once it settles.

Solutions

Use warm water and mild soap as a general household cleaning product.
Instead of abrasive cleaners for scrubbing, use baking soda.
For windows and other glass surfaces, use a mixture of vinegar and water.
Avoid “dry-dusting,” and instead use a rag dampened with water.
Rather than sweeping floors, which kicks up dust, use a vacuum with a HEPA filter that traps dust and dirt particles preventing them from returning to the air.
Use a vacuum with a dusting attachment for items that are hard to dust like lampshades and drapes.

Conclusion

Maintaining a clean and healthy home, including good indoor air quality, might take a little extra work during the holidays. But in between the chores, you and your loved ones will better enjoy the festivities. A cleaner home means a healthier home, and after all, healthier holidays are happier holidays.

Learn how pollution affects exercise performance and health—and how to adjust workouts when air indoor and outdoor air quality shifts.

","Most of us exercise to strengthen our bodies and minds, yet the air we breathe during a workout is often overlooked. Air quality can significantly affect both exercise performance and overall health, particularly during high-intensity or prolonged workouts. As breathing rate increases, exposure to airborne pollutants increases along with it. In enclosed spaces like gyms and studios, poor ventilation can allow pollutants to build up, potentially undermining the benefits of physical activity. With the right awareness and a few practical adjustments, it’s possible to protect your lungs and get more out of every workout. Here’s how air quality affects exercise—and what to do about it. How air quality impacts your workout When you exercise, your breathing deepens and quickens. While this flood of oxygen fuels your muscles, it also means you’re inhaling more of whatever else is in the air: dust, mold, volatile organic compounds (VOCs) from cleaning products, and even PM2.5 —tiny particulate matter measuring less than 2.5 microns in diameter—can enter your lungs and circulate throughout the body. Studies confirm that indoor air pollution levels in gyms often surpass WHO safety limits (1). During a high-intensity workout, you might inhale 90 liters of air per minute or more, compared to just 6 liters at rest (2). That’s 18 times more pollutants entering your lungs and bloodstream—where they can trigger inflammation and limit oxygen delivery to working muscles. Both PM2.5 and gases like carbon dioxide (CO2) accumulate quickly in enclosed spaces. These irritants inflame airways, making it harder to breathe deeply and efficiently. Over time, this can lead to chronic oxidative stress, weakening lung function and endurance. A 2018 study found that gyms in Brazil, France, and other areas of Europe had CO2 levels exceeding 1,000 ppm, a threshold linked to cognitive decline and fatigue (3). Poor ventilation was the primary contributor. Indoor air can harbor two to five times more pollutants than outdoor air, according to the U.S. EPA (4). Why indoor air quality matters during exercise It’s easy to assume that indoor workout spaces are inherently cleaner than the air outdoors. In reality, indoor air quality can vary widely depending on ventilation, occupancy, and cleaning practices. During exercise, deeper and faster breathing increases exposure to airborne pollutants—even when they’re present at levels that might go unnoticed at rest. A gym that looks clean or smells fresh may still contain elevated levels of particulate matter or carbon dioxide, particularly during busy classes or peak hours. This doesn’t mean indoor exercise is unsafe—it means air quality plays a larger role in workouts than many people realize, and that managing ventilation and filtration can make a meaningful difference. Health risks of exercising in polluted air The effects of poor air quality are measurable, both immediately and over time. Fatigue and reduced performance: Exposure to PM2.5 has been found to increase fatigue, affecting athletic performance (5). Respiratory issues: Regular exposure to air pollutants is linked to asthma-like symptoms and decreased lung capacity, even in healthy individuals, due to increased respiratory demands (6). Cardiovascular risks: A systematic review of studies focused on endurance exercise and air pollution shows that athletes exposed to elevated PM2.5 levels were significantly impacted with cardiovascular health problems (7). Mental health impacts: Chronic inflammation from poor air quality is associated with increased risk of depression and anxiety, undermining the mood-boosting effects of physical activity (8). When to adjust your workout for air quality Air quality doesn’t have to be “Hazardous” to affect exercise performance. Because breathing rates increase during physical activity, even moderate pollution can have a greater impact during intense or prolonged workouts. The key is knowing whether you’re responding to indoor air conditions or outdoor pollution levels—and adjusting accordingly. Indoors: watch ventilation and buildup For indoor workouts, elevated PM2.5 levels or carbon dioxide (CO₂) concentrations above 1,000 parts per million (ppm) can signal that ventilation may be inadequate—especially in crowded or enclosed spaces. When these levels rise, lowering workout intensity, shortening duration, improving ventilation, or choosing a less crowded space can help reduce unnecessary strain on the lungs and cardiovascular system.Outdoors: use air quality ranges to guide decisionsFor outdoor exercise, PM2.5 and overall air quality levels are more useful decision tools. As a general guide: Good (0–25): Air quality is good. Outdoor exercise is generally safe. Moderate (26–50): Air quality is acceptable, but sensitive individuals may notice symptoms during outdoor exercise. Moderately Unhealthy (51–100): Pollutants may affect breathing even in healthy individuals. Consider exercising indoors or keeping outdoor workouts shorter and less intense. Unhealthy for Sensitive Groups (101–150): Everyone may be affected, especially those with heart or lung conditions. Indoor exercise is the safer choice. Very Unhealthy (151–200): Health effects are more likely for everyone. Avoid outdoor exercise. Hazardous (201–500): Air quality is poor enough to pose serious health risks. Stay indoors and avoid physical exertion. Using these ranges helps shift workouts to safer times, locations, or environments—without avoiding exercise altogether. Using air quality data to plan your workouts Air quality can change quickly due to traffic patterns, weather, and human activity. Pollution levels that are low early in the day may rise within hours, particularly during rush hour or in enclosed indoor spaces with high occupancy. Checking real-time air quality data and short-term forecasts helps you decide when and where to exercise with less exposure. Monitoring pollutants like PM2.5 and carbon dioxide allows you to adjust workout timing, intensity, or location accordingly—such as exercising earlier, choosing a less crowded space, or prioritizing indoor workouts when outdoor air quality is poor.

New research highlights how air pollution can quietly disrupt sleep — and treatments that can help restore your sleep.

","We all know air pollution harms the heart, lungs, and brain — but new evidence shows it can also steal our sleep.A comprehensive study out of Johns Hopkins University School of Nursing analyzed data from more than 1.2 million adults across six countries. The results are striking: people exposed to higher levels of air pollution, including fine particulate matter (PM2.5), nitrogen dioxide (NO₂), and carbon dioxide (CO₂), consistently reported shorter or poorer-quality sleep (1).Sleep is foundational to immune function, cognitive performance, and emotional regulation — making air quality a powerful factor in how well we rest.What makes this connection especially important is that sleep isn’t just a nightly routine — it’s a biological reset that pollution can quietly disrupt without us noticing.From early childhood through older adulthood, disrupted sleep compounds health risks — making air quality a quiet but consistent influence on sleep health. The hidden link between air pollution and sleep Sleep is shaped by far more than light, noise, or bedtime habits. The air we breathe—hour after hour, night after night—plays a subtle but powerful role in how deeply we sleep, how often we wake, and how well the body recovers overnight. According to the study, even modest pollution increases were linked with restless nights, insomnia, and shorter sleep duration — more impactful effects than scientists expected. “Air quality – both outdoors and inside the home – is an underrecognized contributor to sleep problems,” said Dr. Junxin Li, lead researcher for the study. “Cleaner air not only safeguards lungs and hearts, it also helps people sleep, supporting cognition, mood, and overall resilience.” These findings point to a broader pattern: air pollution doesn’t just affect sleep in extreme conditions, but subtly influences sleep quality across populations, environments, and everyday exposure levels. Cleaner air…helps people sleep, supporting cognition, mood, and overall resilience.”—Dr. Junxin Li, Johns Hopkins University What the research show The review combined findings from 25 high-quality studies conducted since 2015, covering adults over 45 years old in China, India, the U.S., Germany, and other nations. It was found that cutting average PM2.5 concentrations in half—from the levels typically found on busy city streets down to the World Health Organization (WHO) guideline—could reduce the likelihood of poor sleep by about 10 percent among middle-aged and older adults. In other words, cleaner air could help millions of people gain roughly an extra hour of rest each night. That insight helps explain why sleep disruption shows up not only in polluted cities, but also in everyday indoor spaces where people spend much of their lives. Indoor air matters, too While outdoor air pollution often gets the most attention, indoor air quality plays a critical role in sleep health—especially because people spend nearly a third of their lives asleep indoors. For many adults, nighttime exposure inside the home may represent their longest and most consistent contact with air pollution. Dr. Li’s team found that indoor pollution can be just as harmful — especially for older adults, who often spend most of their time indoors. Only six high-quality studies examined indoor sources, but their conclusions were clear: households using solid fuels such as coal or wood for cooking or heating reported far worse sleep outcomes than those using clean energy. And homes that used ventilation fans or opened windows during cooking saw notable improvements in sleep quality — evidence that even small steps to improve indoor air can matter. Sleep quality isn’t shaped only by what happens during the day, but by the air we’re exposed to night after night—making it important to understand how air pollution disrupts sleep in the first place. How air pollution disrupts sleep quality Air pollution can interfere with sleep quality through inflammation, nervous-system stimulation, and reduced oxygen exchange during the night. Prolonged exposure to even low-level pollutants can interfere with the body’s natural recovery processes.Unlike daytime exposure — which is intermittent — sleep creates a long, uninterrupted window where the body is continuously affected by the air it breathes. That makes nighttime air quality especially influential, even when pollution levels are relatively low.Scientists are still uncovering the mechanisms linking pollution to sleep problems, but several pathways are already well-understood: Inflammation and oxidative stress: Fine particles penetrate deep into the lungs and bloodstream, triggering systemic inflammation that can disturb normal sleep cycles. Nervous-system stimulation: Nitrogen dioxide and other gases can activate stress responses that increase heart rate and restlessness. Reduced oxygen exchange: Elevated CO₂ levels in bedrooms can lower oxygen availability, fragmenting deep sleep and REM phases. Noise and thermal effects: Polluted urban environments often coincide with traffic noise and higher nighttime temperatures — both known sleep disruptors. The outcome? More tossing, turning, and waking — and fewer restorative hours of rest. How clean air supports deeper, more restorative sleep When the air you breathe is free of pollutants, your body can maintain balanced oxygen and carbon-dioxide levels. Your heart rate stays steady, airways remain open, and inflammation decreases. That supports slow-wave (deep) sleep, the stage critical for physical repair and immune recovery. Nights spent in cleaner air environments showed measurable improvements in sleep efficiency and oxygen saturation. In studies of adults with asthma or cardiovascular disease, nights spent in cleaner air environments showed measurable improvements in sleep efficiency and oxygen saturation. Over time, better sleep quality is linked to lower cardiovascular risk, stronger immune response, improved memory, and better mental health — amplifying the health benefits of cleaner air beyond the bedroom. Indoor air quality while you sleep During sleep, we spend several uninterrupted hours breathing the air in a single enclosed space. Unlike daytime hours—when doors open, windows are used, and air is constantly exchanged—bedrooms often become more sealed at night, allowing pollutants to accumulate. Research shows that indoor air pollution can exceed outdoor levels by two to five times, especially overnight when ventilation is reduced. For people living near busy roads, dense urban corridors, or industrial areas, nighttime exposure may remain elevated—even when outdoor air quality appears good during the day. The encouraging news is that many of the most common bedroom pollutants are well understood—and highly controllable once identified. Understanding where these pollutants come from makes it easier to reduce exposure and create a sleep environment that supports the body’s natural overnight recovery. Common bedroom pollutants include: PM2.5 and ultrafine particles — from traffic exhaust, cooking, and candles.Impact: Can increase inflammation and interfere with deep, restorative sleep. Nitrogen dioxide (NO₂) — from gas stoves and heaters.Impact: May trigger airway irritation, wheezing, and nighttime restlessness. Volatile organic compounds (VOCs) — from cleaning products, paints, and new furniture.Impact: Can contribute to headaches, dizziness, and difficulty falling asleep. Carbon dioxide (CO₂) — from human exhalation in sealed rooms.Impact: Higher levels are associated with drowsiness and fragmented sleep. With the right combination of ventilation, monitoring, and filtration, these exposures can be significantly reduced—helping create a calmer, more supportive environment for sleep. Clean air solutions for better rest Improving sleep through cleaner air isn’t about perfection — it’s about reducing exposure where it matters most, during the hours your body is working hardest to recover. Sleep is a prolonged, uninterrupted activity, so small improvements in air quality can have an outsized impact overnight. Protecting sleep quality requires a layered approach to improving indoor air quality: Monitor indoor and outdoor air quality: Tracking conditions with an air quality monitor helps identify patterns—such as elevated PM2.5 or CO₂ levels at night—and informs when ventilation or filtration is most beneficial. Real-time data makes it easier to respond proactively rather than guessing. Downloading an air quality app can also provide outdoor air quality in the palm of your hand. Ventilate strategically: When outdoor air quality is good, opening windows or using extractor fans during cooking and cleaning helps prevent pollutants from building up indoors. Even brief ventilation before bedtime can lower overnight exposure. Use high-performance filtration where you sleep: Because the smallest particles are most likely to penetrate deep into the lungs and disrupt sleep, filtration that captures ultrafine particles is especially important in bedrooms. Air purifiers with HyperHEPA filtration are designed to remove particles far smaller than the limits of standard HEPA. Together, these steps help create an indoor environment that works with the body’s natural sleep processes, making cleaner air an enabler of deeper, more restorative rest. Studies suggest that improvements in bedroom air quality can influence sleep quality within days or weeks, not just over months or years. Conclusion Sleep is one of the body’s most powerful recovery tools — and the air you breathe plays a meaningful role in how well it works. By reducing exposure to particulate pollution indoors and out, you can support healthier sleep, protect your lungs, heart, and brain, and give your body the restorative rest it needs—especially over the long term.","

Studies suggest that improvements in bedroom air quality can influence sleep quality within days or weeks, not just over months or years.

Conclusion

Sleep is one of the body’s most powerful recovery tools — and the air you breathe plays a meaningful role in how well it works.

By reducing exposure to particulate pollution indoors and out, you can support healthier sleep, protect your lungs, heart, and brain, and give your body the restorative rest it needs—especially over the long term.

Explore 5 practical ways to reduce waste during Ramadan—food, plastics, water, energy, and transportation—and emphasizing the spirit of renewal.

","For roughly a quarter of the world’s population, Ramadan is a month that reshapes daily life — from meals and prayer to family gatherings and community care (1). It’s a deeply meaningful season, and for many, a chance to recommit to living with intention. Because daily routines change so much during Ramadan — what we cook, what we buy, how we gather, and how we travel — it can also be a natural moment to reduce waste and use shared resources more thoughtfully. Ramadan, in brief Ramadan is the ninth month of the Islamic calendar, observed through fasting from dawn to sunset, prayer, and acts of charity. At its heart, it’s about renewal, self-discipline, gratitude, and caring for others — values that naturally support more mindful choices in everyday life. Here are five simple tips to get started. 1. Plan meals to reduce food waste Iftar (the evening meal that breaks the fast) and suhoor (the pre-dawn meal before fasting begins) are meaningful moments, and it’s common to overestimate how much food a household (or a gathering) will actually need. The result isn’t just extra dishes and leftovers. Food waste also represents wasted water, packaging, and energy. Ramadan is a time to pause and reflect on what we truly need — and to treat food as a blessing, not a given. A helpful mindset shift is to plan Ramadan meals the way you might plan for hosting: start with what you know you’ll use, then leave room to adjust. Try planning a few days at a time instead of shopping “for the whole week,” especially early in the month while you’re learning your family’s rhythm. A simple approach that works for many households: Shop with a short list. Buy what you can realistically cook and finish. Cook modestly, then add. It’s easier to make a little more than to undo too much. Give leftovers a purpose. For instance, tonight’s iftar can become tomorrow’s suhoor. If you do end up with extra, consider sharing it intentionally — with neighbors, friends, or anyone who might benefit. It keeps the spirit of generosity intact while preventing waste. 2. Cut single-use plastics at iftars and gatherings Community iftars and mosque nights are some of the most beautiful parts of Ramadan. They can also be where waste quietly piles up: plastic water bottles, cups, plates, and cutlery — often used for minutes and then and can remain in the environment for years. Ramadan is a month of gathering, so it’s an opportunity to gather thoughtfully, with small choices that reduce waste and what we throw away. 3. Conserve water, especially during wudu and in the kitchen Water use often increases during Ramadan: more cooking, more cleaning, more wudu (ritual washing before prayer), more guests. Because the month is busy, it’s easy to use more than necessary without noticing. Ramadan is a reminder that intention can show up in small moments — including how we use everyday resources like water. Instead of treating water conservation like a major lifestyle overhaul, treat it like mindfulness: small, repeated moments of intention. In daily routines, that can look like: Turning off the tap while brushing your teeth Avoiding continuously running water during wudu Washing produce in a bowl instead of under a running faucet If your mosque provides bottled water, another simple step is to finish what you take and dispose of it properly — or bring your own reusable bottle so fewer bottles are left behind at the end of the night. In many regions, water is already a scarce resource. Mindful use is practical and deeply aligned with the month’s emphasis on gratitude. An eco-friendly Ramadan isn’t about perfection. It’s about small choices that add up across households and communities. 4. Use less energy and practice conscious consumption Ramadan evenings often run late. Lights stay on longer. Kitchens stay busy. Families make extra store trips. None of this is “wrong” — it’s simply part of how Ramadan changes the rhythm of life. But the month can also be an invitation to simplify: to reduce what’s unnecessary, keep what’s meaningful, and build habits you’ll want to continue. That’s the heart of reflection — noticing where our routines drift into excess and gently returning to what matters. One way to think about energy and consumption during Ramadan is: reduce the “background” load. The small, forgettable things that add up. A few low-effort shifts: Turn off lights, chargers, and appliances when they’re not in use Swap to energy-efficient bulbs where possible Reduce store trips by planning ahead (one larger trip instead of many small ones) Avoid impulse purchases and overbuying “just in case” And if you want a non-technical “reset” that fits the spirit of the month: swap a bit of screen time for something quieter — reading, reflection, or community time. 5. Rethink transportation and build community habits During Ramadan, trips to the mosque, grocery store, and family gatherings can add up quickly, especially in communities where events run nightly. Transportation is one of those areas where small changes can have a collective impact. Ramadan is about community care, and how we move and how often we drive can be part of that care. If it’s feasible in your area, walking or cycling to prayers can reduce fuel and road use while adding something surprisingly valuable: a calm transition into the evening. When distance or safety makes that unrealistic, community habits can still help: Carpool for taraweeh (special evening prayers during Ramadan) or community events Combine errands into one trip instead of several Keep tires properly inflated to improve fuel efficiency When these habits spread across a neighborhood, they don’t just reduce environmental impact, they also strengthen community connection, which is part of what Ramadan is about. The takeaway Eco-friendly habits don’t have to feel like a separate “project.” They can be part of what Ramadan already teaches: intentional living, moderation, and gratitude. If you choose just one change this month, make it a simple one — and make it consistent. Small actions, repeated across weeks of Ramadan and shared across communities, can carry forward long after Eid.","

Ramadan, in brief

Ramadan is the ninth month of the Islamic calendar, observed through fasting from dawn to sunset, prayer, and acts of charity. At its heart, it’s about renewal, self-discipline, gratitude, and caring for others — values that naturally support more mindful choices in everyday life.

Here are five simple tips to get started.

1. Plan meals to reduce food waste

Iftar (the evening meal that breaks the fast) and suhoor (the pre-dawn meal before fasting begins) are meaningful moments, and it’s common to overestimate how much food a household (or a gathering) will actually need. The result isn’t just extra dishes and leftovers. Food waste also represents wasted water, packaging, and energy. Ramadan is a time to pause and reflect on what we truly need — and to treat food as a blessing, not a given.

A helpful mindset shift is to plan Ramadan meals the way you might plan for hosting: start with what you know you’ll use, then leave room to adjust. Try planning a few days at a time instead of shopping “for the whole week,” especially early in the month while you’re learning your family’s rhythm.

A simple approach that works for many households:

Shop with a short list. Buy what you can realistically cook and finish.
Cook modestly, then add. It’s easier to make a little more than to undo too much.
Give leftovers a purpose. For instance, tonight’s iftar can become tomorrow’s suhoor.

If you do end up with extra, consider sharing it intentionally — with neighbors, friends, or anyone who might benefit. It keeps the spirit of generosity intact while preventing waste.

2. Cut single-use plastics at iftars and gatherings

Community iftars and mosque nights are some of the most beautiful parts of Ramadan. They can also be where waste quietly piles up: plastic water bottles, cups, plates, and cutlery — often used for minutes and then and can remain in the environment for years. Ramadan is a month of gathering, so it’s an opportunity to gather thoughtfully, with small choices that reduce waste and what we throw away.

3. Conserve water, especially during wudu and in the kitchen

When these habits spread across a neighborhood, they don’t just reduce environmental impact, they also strengthen community connection, which is part of what Ramadan is about.

The takeaway

Eco-friendly habits don’t have to feel like a separate “project.” They can be part of what Ramadan already teaches: intentional living, moderation, and gratitude.

If you choose just one change this month, make it a simple one — and make it consistent. Small actions, repeated across weeks of Ramadan and shared across communities, can carry forward long after Eid.

Don’t wait for smoke to fill the skies – follow these tips to be ready for crop burning season this year.

","Crop burning is the deliberate burning of agricultural leftovers, such as rice straw or wheat stubble, to clear fields quickly for the next planting cycle. Crop burning smoke can travel hundreds of miles and linger for days or weeks, depending on weather conditions. Millions of tons of crop residue are burned annually, sending smoke into distant cities and neighboring countries (1). Agricultural fire smoke creates a recurring seasonal health problem that disrupts daily life, strains healthcare systems, and deepens the global burden of air pollution. In the weeks leading up to crop burning season, it’s critical to make a plan to avoid exposure to smoke and airborne pollutants. What is crop burning? Crop burning is a fast, low-cost way to clear leftover plant material after harvest. Farmers may burn straw, stalks, or stubble directly in the field, or pile residues and burn them in one place. For many growers, time is critical. There is often only a short window between harvest and the next planting. Burning can remove heavy residue quickly, reduce certain pests or plant diseases, and prepare fields faster than mechanical methods that require extra fuel, labor, and equipment passes. Burns often happen in that narrow window between harvest and planting, which is why smoke shows up seasonally. Weather plays a major role, and wind can carry smoke far beyond the field, while still air can trap it closer to the ground. Burning is efficient, but it comes with trade-offs. Some nutrients in crop residue—especially nitrogen and sulfur—can turn into gases and drift away with the smoke. Others, like phosphorus and potassium, remain in the ash, which can blow away or wash off the field before those nutrients return to the soil (2). The science behind the smoke When crops burn, they release a complex, invisible cocktail of pollutants. When crops burn, they release a complex, invisible cocktail of pollutants. At the forefront is PM2.5, particulate matter measuring 2.5 microns or less in diameter. These microscopic particles are small enough to bypass some of the body’s defenses, reach deep into the lungs, and in some cases enter the bloodstream. PM2.5 can trigger inflammation, worsen asthma, and is linked to long-term risks like lung cancer and heart disease. Crop burning smoke can also release carbon monoxide, nitrogen oxides, and volatile organic compounds (VOCs), all pollutants that can negatively impact human health. Studies have found links between crop burning spikes and rises in hospital admissions for respiratory diseases, including asthma (3). Who is most at risk? When crop burning season arrives, the health burden falls greatest on those individuals who are the most vulnerable. Children, whose lungs are still developing, face heightened risks of asthma and stunted lung growth from prolonged exposure to PM2.5 (4). The elderly, especially those with pre-existing heart or lung conditions, see hospitalizations surge as fine particles deepen inflammation and exacerbate chronic diseases (5). For outdoor workers, including farm workers, there’s no escaping the impact of crop residue smoke. For outdoor workers, including farm workers, there’s no escaping the impact of crop residue smoke. Their livelihoods force them into the thick of the pollution, where every breath increases the risk of severe respiratory distress. People with asthma and other chronic respiratory diseases can be strongly impacted by the smoke. Repeated exposure to PM2.5 from smoke aggravates asthma, decreases lung function, and is linked to premature death (6). In urban populations downwind, particularly in densely packed cities with poor ventilation, smoke settles into a stubborn haze. Low-income communities, often lacking access to air filtration or healthcare, are hit hardest. Where is crop burning most common? Crop residue burning happens in agricultural regions worldwide. It tends to be most prevalent where large harvests are followed by a short turnaround to the next planting, and where residue is difficult to manage quickly with equipment, labor, or storage options. South Asia Burning is widespread after harvests, especially for wheat, rice, and maize stubble. Smoke can drift across borders, affecting parts of Pakistan, northern India, Bangladesh, and Nepal (7). During the post-monsoon burning season, studies estimate crop-residue burning can contribute about 30–34% of surface PM2.5 on average, and about 50–56% during plume events that transport smoke downwind toward major population centers (8). East Asia China has worked to curb crop stubble burning, but enforcement varies and seasonal burning persists—particularly in parts of Northeast China (9). Southeast Asia In mainland Southeast Asia, seasonal haze has been strongly linked to open biomass burning, a category that includes agricultural residue burning along with other burning types. One regional analysis estimated open biomass burning contributed about 57% of PM2.5 concentrations across parts of mainland Southeast Asia during the period studied. In addition to crop residue burning, land clearing practices in countries such as Laos, Thailand, and Indonesia contribute to seasonal haze. Smoke can travel across national borders and affect neighboring countries downwind. Regional coordination has increased, and the Association of Southeast Asian Nations (ASEAN) has pledged to phase out the practice across member states (10) Europe Many European Union member states and the United Kingdom have strong restrictions on open burning. Even so, smoke can still drift in from neighboring countries where enforcement is weaker or where rules differ (11)(12). United States In the United States, agricultural burning occurs in multiple crop systems and has been identified as an understudied health concern for some rural communities, including parts of the Upper Great Plains . In EPA’s 2020 National Emissions Inventory (NEI), agricultural burning is shown as a measurable PM2.5 emissions source, with emissions concentrated in Florida, Washington, Georgia, and Horth Dakota, among others (13). Global and local efforts to curb crop burning The first step in preparing for crop burning season is to eliminate the smoke at its source. If farmers lack access to alternatives to residue burning and enforcement is inconsistent, there can be mitigation challenges. But there are promising solutions that combine top-down policies with grassroots adoption of new technologies. The first step in preparing for crop burning season is to eliminate the smoke at its source. For instance, India provides subsidies for “happy seeders,” machines that plant new crops without burning stubble. Farmers who adopted the technology were able to cut costs on land preparation, irrigation, and fuel use while still maintaining consistent, moderate crop yields (14). China’s strict bans and enforcement via satellite surveillance helped reduce fires in key provinces like Heilongjiang (15). However, controlled fires are starting to make a comeback as some local officials are loosening restrictions. While there are companies and initiatives to pay farmers for stubble use as biofuels or animal feed, greater subsidies may be needed to support farmers due to the high supply and low demand for crop waste. Turning waste into income offers a powerful alternative to the traditional burns. For instance, in Southeast Asia, Thailand and Vietnam are piloting programs to convert rice straw into biofuel or compost, turning waste into revenue (16) (17). If you live downwind of agricultural regions—or you’ve seen seasonal haze before—planning ahead can reduce exposure when smoke returns. How to protect your family and community Stopping the fires at their source is critical. Even so, it’s essential to develop an action plan and know what steps to take before smoke begins to drift into homes and businesses. What governments, communities, and organizations can do Pass legislation strongly limiting crop burning and regularly enforcing those laws. Support local farmers by providing subsidies for no-burn equipment and techniques. Push local, regional, and national officials for stricter enforcement of burning bans. Report violations to local environmental agencies. Help connect farmers with cooperatives that offer affordable rentals of no burn equipment. What individuals can do Before smoke arrives: Set up a simple monitoring routine: check PM2.5 and the Air Quality Index (AQI) regularly so you can spot poor air quality conditions early. Ventilate only when outdoor air is clean. Prep your indoor air plan: identify a “clean room” (usually a bedroom or living room) where you can keep windows closed and run a high-performance air purifier. If you may need to be outdoors during smoky periods, keep a well-fitted pollution mask on hand. When smoke is high: Keep windows and doors closed and avoid bringing smoky air indoors. Reduce indoor pollution sources that add particles to the air (for example: don’t burn candles, limit frying or high-smoke cooking). Move exercise and kids’ playtime indoors until air quality improves. If you must go outside, wear a well-fitted face mask and keep outdoor time as short as possible. Run a high-performance air purifier consistently, especially in your clean room.

Microplastics are a growing health concern – so can an air purifier remove these from the air we breathe? Find out more.

","Yes—high-efficiency, filtration-based air purifiers can reduce airborne microplastics. Airborne microplastics are typically fibers and fragments that range from visible specks down to microscopic particles. Some research also discusses nanoplastics (much smaller plastic particles), which may behave more like ultrafine particles in air. A well-designed air purifier that uses mechanical filtration (HEPA/HyperHEPA-class) can capture airborne plastic fibers and fragments as air passes through the filter—reducing how much of this material remains suspended indoors. Because filtration performance depends on the full system (airflow + seal + filter media), the most reliable results come from purifiers built for high particle removal efficiency over time. What are microplastics? Microplastics are small pieces of plastic typically defined as less than 5 millimeters in size. In the air, microplastics often show up as tiny fibers (for example, from synthetic textiles) or irregular fragments (from degraded plastics) (1). You may also see the term nanoplastics, which refers to even smaller plastic particles—often discussed as particles smaller than 1 micrometer. In practical terms: Microplastics are often captured like dust and other similarly sized fibers.

Yes—high-efficiency, filtration-based air purifiers can reduce airborne microplastics. Airborne microplastics are typically fibers and fragments that range from visible specks down to microscopic particles. Some research also discusses nanoplastics (much smaller plastic particles), which may behave more like ultrafine particles in air.

A well-designed air purifier that uses mechanical filtration (HEPA/HyperHEPA-class) can capture airborne plastic fibers and fragments as air passes through the filter—reducing how much of this material remains suspended indoors. Because filtration performance depends on the full system (airflow + seal + filter media), the most reliable results come from purifiers built for high particle removal efficiency over time.

What are microplastics?

Microplastics are small pieces of plastic typically defined as less than 5 millimeters in size. In the air, microplastics often show up as tiny fibers (for example, from synthetic textiles) or irregular fragments (from degraded plastics) (1).

You may also see the term nanoplastics, which refers to even smaller plastic particles—often discussed as particles smaller than 1 micrometer.

In practical terms:

\nMicroplastics are often captured like dust and other similarly sized fibers.
\nNanoplastics behave more like ultrafine particles, which makes high-performance filtration especially important.

See how three pivotal studies changed what the world knows about air pollution—and why that science still matters today.

","Air quality science didn’t advance all at once. It changed through a series of breakthroughs—moments when scientists were able to prove what polluted air was doing to people, where it was coming from, and why it mattered. Some of the most important discoveries began with simple but urgent questions: Why were people getting sick? What was in the air? And could those risks be prevented? Three major turning points reshaped how the world understands air pollution today. Together, they helped transform air quality from an invisible environmental concern into a measurable public health issue—one that continues to guide policy, research, and how communities protect themselves. Scientific breakthroughs only matter if they are shared and acted on. When evidence is delayed, ignored, or dismissed, the consequences can last for years. The history of air quality science shows that progress depends not just on discovery—but on whether societies listen and respond. 1930-1952: Deadly fogs spark modern air quality research In the early 20th century, air pollution was widespread—but poorly understood. That changed when a series of deadly events forced scientists and governments to confront its health impacts. In 1930, a dense industrial fog settled over the Meuse Valley in Belgium. The combination of temperature inversion, trapped emissions, and industrial activity led to 64 deaths. Autopsies found severe respiratory damage, including excess mucus, hemorrhaging and fluid in the lungs. Investigators linked the fatalities to sulfur dioxide and other industrial pollutants, and the findings were published in the Bulletin de l'Académie royale de médecine de Belgique in 1931. It was one of the first connect air pollution with mortality (1). Despite these findings, Belgian authorities laid the blame on chance and local conditions. Ignoring the warnings, other similar, preventable disasters would unfold in later decades in both America and England. Nearly two decades later, a similar disaster struck Donora, Pennsylvania. In October 1948, a temperature inversion trapped emissions from steel and zinc plants, creating a thick smog that killed 20 people and sickened thousands (2). This time, researchers conducted one of the first large-scale epidemiological studies of air pollution, confirming the role of industrial emissions in the disaster. The research team’s findings sparked public outrage and would lay the groundwork for the United States’ Clean Air Act. Then in 1952, London’s Great Smog caused at least 4,000 deaths in just a few days (3). Investigations identified coal burning as the primary source, leading to the United Kingdom’s Clean Air Acts (4). Together, these events and the resulting studies marked a turning point. They showed that polluted air was not just unpleasant—it could be deadly. And they laid the foundation for modern air quality regulation and public health research. 1950s: Dr. Haagen-Smit cracks the LA smog code By the 1940s, Los Angeles was known for its thick, eye-stinging smog—but no one fully understood what was causing it. At the time, many believed smog came primarily from industrial emissions. But Biochemistry professor Dr. Arie Haagen-Smit began a series of experiments in 1948 that revealed smog’s true chemistry. He showed that hydrocarbons and nitrogen dioxide could react in sunlight to form ozone, helping explain the toxic photochemical smog blanketing Los Angeles. His research showed that cars—major emitters of both hydrocarbons and nitrogen dioxide—were central to the city’s air pollution (5). This revelation led to the first vehicle emissions standards (6). Haagen-Smit’s work helped clean the air and transform public perception, forcing policymakers to confront human activity’s role in environmental degradation. 1993: The “Harvard Six Cities” study and the toll of dirty air By the early 1990s, scientists had already established that extreme pollution events could be deadly. The next question was more subtle—and more important for everyday life: what about long-term exposure to lower levels of pollution?

Learn how HyperHEPA filtration captures ultrafine particles far smaller than the HEPA standard, and why that matters for indoor air quality.

","Indoor air often contains a mix of pollutants that are easy to overlook—dust, pollen, smoke, and microscopic particles from traffic or combustion that can stay suspended in the air we breathe. For people with allergies, asthma, or respiratory sensitivities, reducing those particles indoors can make a noticeable difference in comfort and health. A HyperHEPA air purifier is a filtration-based air purifier designed to capture particles far smaller than the size standard commonly associated with HEPA filtration. In simple terms, it is built for environments where reducing ultrafine airborne particles is especially important. To understand why that matters, it helps to start with what standard HEPA filtration does well—and where higher-performance filtration can go further. What is HEPA filtration? HEPA (high-efficiency particulate air) filters are designed to trap 99.97% of particles as small as 0.3 microns, including dust, pollen, pet dander, and mold spores (1)(2). Originally developed during World War II to contain radioactive particles, HEPA technology has since become the industry standard for air purification. It works by forcing air through a dense mat of fibers, where particles are captured through a combination of interception, impaction, and diffusion. However, HEPA filters have limits. They struggle with ultrafine particles smaller than 0.3 microns, including some viruses and combustion particles. In real-world use, filtration performance also depends on the purifier’s design. If air can bypass the filter because of gaps or poor sealing, some polluted air may circulate without being filtered. In real-world use, those limitations can matter most when the air contains large amounts of ultrafine pollution—such as wildfire smoke, traffic-related combustion particles, or other high-particle events. In those situations, filter performance depends not just on the filter media itself, but also on how well the overall system is sealed. What is HyperHEPA filtration? A HyperHEPA air purifier is an air purifier built with filtration media designed to capture 99.5% of particles down to 0.003 microns—100 times smaller than the 0.3-micron benchmark commonly associated with standard HEPA filtration. That matters because many of the particles people worry about most indoors are extremely small. Ultrafine particles from combustion, traffic pollution, smoke, and some airborne biological material can behave differently from larger dust or pollen particles, staying suspended longer and reaching deeper into the respiratory system. A HyperHEPA air purifier is not a different category of appliance from an air purifier—it is a higher-performance particle filtration approach within an air purifier. In practice, that means the purifier is designed not only around the filter media itself, but also around system sealing and airflow so that filtered air is less likely to bypass the filter. Why ultrafine particles matter Not all airborne particles behave the same way. Larger particles, like visible dust or some pollen, settle more quickly. Ultrafine particles are different: they are so small that they can stay airborne longer and move more easily through indoor spaces. That’s one reason wildfire smoke, traffic emissions, and other combustion-related pollution can be so difficult to manage indoors. Even when the air looks clean, ultrafine particles may still be present. A higher-efficiency filtration system is designed to reduce more of those smaller particles from the air people actually breathe. How is HyperHEPA different from HEPA? When comparing HEPA and HyperHEPA filtration, the main differences come down to particle size performance and system design. Particle size range HEPA filters are designed to capture 99.97% of particles at 0.3 microns. This covers many common indoor particles such as dust, pollen, and mold spores. HyperHEPA filtration is designed to capture 99.5% of particles down to 0.003 microns, extending protection deeper into the ultrafine range. Real-world filtration performance A filter’s effectiveness depends not only on the media, but also on how well the purifier is built. If air bypasses the filter because of gaps or leakage, overall performance drops. HyperHEPA systems are typically designed with tighter sealing so that more of the air moved through the unit is actually filtered rather than escaping around the filter. This difference matters most when indoor air contains a large amount of ultrafine pollution, such as smoke, traffic-related particles, or other combustion byproducts. How to think about air purifier claims Not every air-cleaning technology works in the same way. Some systems are designed to capture pollutants, while others claim to destroy, neutralize, or transform them. That distinction matters. Physical filtration removes particles from circulation by trapping them in filter media. Other technologies may rely on chemical reactions, ionization, or light-based processes, and their effectiveness can vary depending on the pollutant, the room, and how the system is used. When evaluating an air purifier, it helps to ask a few simple questions: What pollutants is it actually designed to address? A good purifier should clearly state whether it is built for particles, gases and odors, or both. Particle filters address things like dust, pollen, smoke, and ultrafine particles; gases and VOCs require sorbent media such as activated carbon. Does it physically remove particles from the air? This is one of the clearest signs of a strong air-cleaning approach. Filtration-based systems trap particles in filter media instead of trying to alter them in the air or push them onto nearby surfaces. Does it rely on added reactive chemistry or generate byproducts? If a purifier uses ozone, ionization, or other reactive processes, it’s worth asking what else may be created along the way. A stronger approach is one that removes pollutants without adding new ones to the room. Is its performance based on clear, testable standards? Look beyond broad marketing claims. CADR can help show how quickly a purifier reduces particles in a room under short-term test conditions, but it does not tell you how performance holds up over time. CCM is useful because it reflects how well a purifier continues performing as filters load with pollutants, giving a better picture of long-term effectiveness. A stronger air purifier claim is usually a simpler one: capture pollutants efficiently, move enough air, and maintain that performance over time. Conclusion A HyperHEPA air purifier is a filtration-based air purifier built to capture extremely small airborne particles—well beyond the particle-size range most people associate with standard HEPA. That makes it especially relevant in situations where ultrafine pollution matters, such as wildfire smoke, traffic emissions, and other combustion-related indoor air concerns. The key idea is simple: don’t look only at whether a purifier says “HEPA.” Look at how small a particle it is designed to capture, how the system is sealed, and whether the overall design supports real-world performance over time.","

\nHEPA filters are designed to capture 99.97% of particles at 0.3 microns. This covers many common indoor particles such as dust, pollen, and mold spores.
\nHyperHEPA filtration is designed to capture 99.5% of particles down to 0.003 microns, extending protection deeper into the ultrafine range.

Real-world filtration performance

A filter’s effectiveness depends not only on the media, but also on how well the purifier is built. If air bypasses the filter because of gaps or leakage, overall performance drops.
HyperHEPA systems are typically designed with tighter sealing so that more of the air moved through the unit is actually filtered rather than escaping around the filter.

This difference matters most when indoor air contains a large amount of ultrafine pollution, such as smoke, traffic-related particles, or other combustion byproducts.

How to think about air purifier claims

Not every air-cleaning technology works in the same way. Some systems are designed to capture pollutants, while others claim to destroy, neutralize, or transform them.

That distinction matters. Physical filtration removes particles from circulation by trapping them in filter media. Other technologies may rely on chemical reactions, ionization, or light-based processes, and their effectiveness can vary depending on the pollutant, the room, and how the system is used.

When evaluating an air purifier, it helps to ask a few simple questions:

\nWhat pollutants is it actually designed to address? A good purifier should clearly state whether it is built for particles, gases and odors, or both. Particle filters address things like dust, pollen, smoke, and ultrafine particles; gases and VOCs require sorbent media such as activated carbon.
\nDoes it physically remove particles from the air? This is one of the clearest signs of a strong air-cleaning approach. Filtration-based systems trap particles in filter media instead of trying to alter them in the air or push them onto nearby surfaces.
\nDoes it rely on added reactive chemistry or generate byproducts? If a purifier uses ozone, ionization, or other reactive processes, it’s worth asking what else may be created along the way. A stronger approach is one that removes pollutants without adding new ones to the room.
\nIs its performance based on clear, testable standards? Look beyond broad marketing claims. CADR can help show how quickly a purifier reduces particles in a room under short-term test conditions, but it does not tell you how performance holds up over time. CCM is useful because it reflects how well a purifier continues performing as filters load with pollutants, giving a better picture of long-term effectiveness.

A stronger air purifier claim is usually a simpler one: capture pollutants efficiently, move enough air, and maintain that performance over time.

Conclusion

A HyperHEPA air purifier is a filtration-based air purifier built to capture extremely small airborne particles—well beyond the particle-size range most people associate with standard HEPA. That makes it especially relevant in situations where ultrafine pollution matters, such as wildfire smoke, traffic emissions, and other combustion-related indoor air concerns.

The key idea is simple: don’t look only at whether a purifier says “HEPA.” Look at how small a particle it is designed to capture, how the system is sealed, and whether the overall design supports real-world performance over time.

Uncover how airborne pathogens spread and what can be done to protect yourself against them.

","Many infectious diseases, from influenza to measles, can travel through the air in microscopic particles known as aerosols. These particles can linger, move through indoor spaces, and be inhaled by others—making them a critical factor in how infections spread. The risks from airborne pathogens are ever-present, and effective strategies are essential to mitigate their impact. How infectious agents become airborne Aerosols are microscopic solid or liquid particles in air or other gases (1). Aerosols range in size from extremely small particles to larger droplets, and many are small enough to remain suspended in the air for extended periods; research has revealed that the smaller sized aerosols can remain suspended in the air for hours, making them a highly efficient vehicle for infectious agents (2). Some of the smallest airborne particles, such as PM2.5, or particulate matter measuring 2.5 micrometers or smaller, can carry viruses, bacteria, or fungi, allowing them to spread beyond close contact and infect individuals who inhale them (3)(4). Pathogens become airborne through coughing, sneezing, and talking; even normal breathing can release infectious aerosols into the environment. Pathogens – including viruses, bacteria, and fungi – become airborne through coughing, sneezing, and talking; even normal breathing can release infectious aerosols into the environment. When an infected person exhales, tiny droplets containing the pathogen evaporate, leaving behind even smaller particles that remain airborne. This infection process is particularly effective in indoor settings, where poor ventilation can trap and concentrate these particles, increasing the risk of transmission (5). Several factors influence how effectively airborne pathogens are spread: Particle size determines how long they stay aloft—smaller particles travel farther and remain suspended longer. Humidity affects their stability; some viruses thrive in dry air, while others persist better in humid conditions (6). Ventilation plays a crucial role. Stagnant air allows aerosols to accumulate, while proper airflow dilutes and removes them. As a group of Montreal-based teachers, scientists, and doctors demonstrated in an unofficial study conducted in 2020, increased carbon dioxide (CO2) accumulated beyond acceptable levels in classrooms through poor ventilation, which may have in turn exposed students and staff to increased risk of exposure to SARS-CoV-2 (7). The duration of exposure also matters; more time spent in contaminated air increases the likelihood of infection. All these factors combined shape the dynamics of airborne transmission. Although airborne transmission is a primary pathway, pathogens can also settle onto surfaces, where they may be transferred through contact—making both air and surface hygiene important in limiting spread. Common airborne pathogens and their risks Among the most well-known airborne threats are viruses that exploit aerosol transmission to infect new individuals. These can include: Influenza: Influenza (or flu) is a contagious respiratory illness. It relies on airborne particles to move between people, often leading to outbreaks in schools, workplaces, and public gatherings (8). Measles: Measles, typically presented by a rash, fever, cough, runny nose, and watery eyes, are extremely contagious. Measles can linger in the air for up to two hours after an infected person leaves a room, infecting those who enter later (9). SARS-CoV-2: This respiratory virus spread COVID-19 globally, with aerosols playing a key role in its transmission (10). Chickenpox: Also known as varicella-zoster, chickenpox spreads through contact, through fluids, and is airborne. (11) Bacteria also pose a significant airborne risk. Mycobacterium tuberculosis, the bacterium responsible for tuberculosis (TB), spreads when infected individuals cough or sneeze, releasing aerosols that can remain infectious for hours (12). Legionella, another bacterial pathogen, thrives in water systems but becomes airborne through contaminated mist or droplets, causing severe pneumonia when inhaled (13). Where and how aerosol transmission happens Aerosol transmission can flourish in spaces with limited airflow. Hospitals, schools, and public transit systems are notable high-risk settings, where infected individuals can unknowingly expose many others to airborne pathogens. In hospitals, medical procedures such as intubation or even routine patient care can generate infectious aerosols, affecting both patients and healthcare providers. Schools, with their densely populated classrooms and shared facilities, can become epicenters during outbreaks of diseases like measles or influenza. Public transit, where ventilation is frequently inadequate, increases the risk of infection as passengers inhale recirculated air over prolonged periods. In these environments, people may be exposed to airborne pathogens even without direct contact with an infected individual. Research has shown that certain public spaces provide ideal conditions for rapid transmission. Research has shown that certain public spaces provide ideal conditions for rapid transmission. For example, a study on measles transmission in a pediatric practice demonstrated that airborne transmission occurred in an office setting, with unvaccinated infants facing an attack rate of 80% (4/5), compared to 7% (2/27) for vaccinated children (14). A 2024 study conducted in Finland found that all but one participant in a senior choir rehearsal were infected with SARS-CoV-2 (15).

EXPLORE NOW Tip 2. Be clean air prepared Prep your car to reduce emissions Do your part to reduce emissions on the road by ensuring your car is as fuel-efficient as possible: (1) Service your vehicle regularly. Make sure the particulate filter is emptied regularly if your car uses diesel. Keep your tires properly inflated. Turn off your car when stationary in traffic. Leaving the engine running when the car is not moving can release many harmful pollutants into the air around you, as well as wasting fuel. Pack accordingly If the air quality changes for the worse while you’re on the road and you still want to go outdoors, a snug-fitting, KN95/FFP2 mask can keep you from breathing dust, pollen, and air pollutants. Tip 3. Optimize air quality while in the car Consider cutting down your exposure to air pollution caused by vehicles. Research shows that living and working near roadways can impact your lung function, which can lead to asthma and cardiovascular disease (2). That’s because pollutants like PM2.5, particulate matter measuring 2.5 microns or smaller, are emitted by vehicles through incomplete fuel combustion. PM2.5, carbon monoxide, carbon dioxide, and volatile organic compounds, or VOCs, are all vehicle emissions that can impact health. To lower your exposure to in-car pollution on the road: Keep a buffer between your vehicle and vehicles in front of you, especially diesel trucks. Roll up your windows at stop signs, traffic lights, or in heavy traffic, close your windows, and set your air on recirculate. Travel those forgotten byways – exploring winding back roads mean less traffic, less traffic lights, and oftentimes, better scenery than you’ll find on the highway! Plan to avoid cities during rush hour traffic if you’re going to stay on the highway. Pay attention to which direction smoke is blowing during wildfire season.

Run a car air purifier. A car air purifier with HyperHEPA Plus particle filtration technology captures commonly found highway pollutants in your car’s interior and prevents them from reaching your breathing space. Tip 4. Sleep safe and sound Air pollutants aren’t limited to the road. Your motel room may appear clean, but the indoor air quality could affect your health and comfort during your overnight stay. Dust, pollen, mold inside walls, and VOCs from cleaning materials can all affect indoor air quality. Dust, pollen, mold inside walls, and VOCs from cleaning materials can all affect indoor air quality in hotels and other lodging.

Setting up a personal air purifier on a bedside table or desk will mean only clean, filtered air reaches the space where you breathe. Tip 5. Enjoy the clean air outdoors Maybe “hitting the road” means not getting in a motor vehicle at all! Instead of driving, consider finding travel alternatives that let you spend more time outdoors – hike, run, camp, walk, or cycle those beautiful vistas already close to home. Big cities like Washington D.C. and New York City have huge parks found on maps of the USA – the National Mall and Central Park respectively – that are fully accessible by public transit; or you can run, walk, or bike to those destinations. If you still want to get away, look for a nearby national park and spend your visit outdoors, outside of your car (3). Check out the park nearest you and see which outdoor activities you can enjoy. Tip 6. Plan longer trips! To deepen your appreciation for a place and lessen your carbon footprint, try planning longer trips and staying in one place. This will prevent excessive travel-related emissions, help you connect with locals, and support the local economy. Alternatively, opt for a nearby domestic stay or staycation. Conclusion Before your next road trip getaway, take control of your air quality. Using these tips will ensure that you and your fellow travelers enjoy the health benefits of clean air, safeguard the environment, and most importantly, truly relax on your road trip.","

First, second, and thirdhand smoke doesn’t disappear when a cigarette is extinguished. Learn how it lingers in the air, spreads across surfaces, and affects indoor environments over time.

","Smoke does not disappear when a cigarette is extinguished. Particles and gases linger in the air and settle onto surfaces, continuing to affect indoor environments long after smoking stops. What many people don’t realize is that these particles don’t just linger—they continuously move between air and surfaces, re-circulating indoors over time. What is firsthand, secondhand, and thirdhand smoke? Traditionally, tobacco smoke is consumed directly through lighting a cigarette and inhaling the substance, also known as firsthand exposure. However, involuntary or indirect modes of consumption can happen daily without a person even realizing it. From secondary inhalation to residue build-up, all the different types of tobacco smoke exposures include (1): Firsthand: Direct inhalation of tobacco smoke chemicals by an individual, commonly resulting in elevated personal health risks from heart disease to lung cancer and respiratory complications. Secondhand: Also known as passive smoking, this is the involuntary or indirect inhalation of tobacco smoke by a non-smoking person. If exposed, individuals could encounter over 7,000 various chemicals, including over 70 carcinogens. Long-term secondhand exposure increases physical and mental health risks, especially when an individual is in ill-ventilated areas or indoor spaces. Thirdhand: Tobacco smoke residue that clings and gradually accumulates on top of commonly exposed surfaces such as furniture, walls, and clothing. The tobacco residue often contains toxins and poisonous compounds that are especially harmful to infants, toddlers, and animals who may encounter and ingest these particles. Unlike airborne smoke that dissipates, thirdhand smoke can persist on surfaces for weeks or even months, continuing to release harmful compounds back into the air long after smoking stops. How tobacco smoke affects indoor air quality When cigarettes are combusted, they release smoke containing high concentrations of PM2.5 and PM10 particulate matter that can linger and migrate. PM2.5 are airborne particles the size of 2.5 microns or less and PM10 encapsulate particles the size of 10 microns or less. When these pollutants are inhaled, they can cause systemic harm to the human body. In enclosed spaces, smoking can raise fine particle concentrations to levels up to 100 times higher than typical outdoor air—turning indoor environments into some of the most polluted spaces people encounter. Smoking also directly contributes to the production of harmful gases and chemical pollutants, commonly known as volatile organic compounds (VOCs). Tobacco smoke specifically has been found to be linked to benzene, a common carcinogen that is known to cause leukemia, bone marrow damage, and anemia through long-term exposure (2). These dynamics are especially pronounced in indoor environments, where airflow is limited and pollutants are more likely to accumulate over time. Indoor smoking leads to long-term exposure Smoking indoors introduces pollutants into a contained environment where they can accumulate, settle, and recirculate over time. Unlike outdoor environments, indoor spaces often lack sufficient airflow to disperse smoke quickly, allowing particles and gases to persist well beyond the act of smoking itself. For this reason, avoiding indoor smoking completely is the most effective way to reduce exposure to both airborne and surface-bound contaminants associated with smoking. Secondhand smoke doesn’t always dissipate outdoors This persistence is not limited to indoor environments. It is often assumed that secondhand smoke quickly disperses outdoors and poses little risk. However, research suggests that this is not always the case—particularly in partially enclosed spaces such as patios, outdoor dining areas, and building entrances. In these environments, secondhand smoke can reach concentrations comparable to indoor spaces where smoking is permitted. Exposure levels can vary depending on the number of smokers, proximity, and airflow conditions, with individuals downwind often experiencing the highest concentrations. Even at a distance, smoke particles can remain detectable and irritating. In some cases, outdoor smoke can drift into adjacent indoor areas or accumulate in semi-enclosed spaces, extending exposure beyond the immediate source (3). Studies have shown that secondhand smoke can be detected and cause irritation at distances of more than 10–20 feet from the source, particularly when individuals are positioned downwind. In outdoor settings with multiple smokers or partial enclosure, exposure levels can approach those found indoors—lasting for as long as smoking activity continues and, in some cases, persisting after the source is gone (4). These findings challenge the assumption that outdoor smoking eliminates risk, highlighting how secondhand smoke can persist and spread across both indoor and outdoor environments. Thirdhand smoke can further extend this exposure. Residual particles that settle onto clothing, skin, or surfaces outdoors can be carried back into indoor environments, where they continue to release harmful compounds over time. This means that even when smoking occurs outside, its effects can still persist indoors. How smoking regulations shape indoor air quality U.S. State and federal smoking laws have been in place since the 1960s to ensure public safety and limit indirect exposure. The Federal Cigarette Labeling and Advertising Act, enacted in July 1965, was one of the first anti-smoking laws, requiring transparent health warnings and restricting false advertising of cigarette products nationwide (5). Today, many policies extend into private spaces, as business owners take it upon themselves to limit tobacco exposure to ensure public safety. Tobacco and smoking regulations are becoming increasingly popular worldwide as well. In 2024, Canada was the first country in the world to mandate transparent health warnings on each cigarette individually, with bold black text printed on every stick (6). Also in the same year, the United Kingdom introduced a Tobacco and Vapes Bill, which would ban those under the age of 15 from purchasing tobacco beginning 2027 (7). In a separate ruling, the United Kingdom has also banned the sell and purchase of disposable vapes to address issues in underage smoking (8). For shared buildings and apartment complexes, anti-smoking regulations and designated smoking areas are the key to securing a healthy space for everyone, as cigarette smoke can be transported easily through open windows and air vents or stick to commonly used surfaces (9).

Smoke does not disappear when a cigarette is extinguished. Particles and gases linger in the air and settle onto surfaces, continuing to affect indoor environments long after smoking stops.

What many people don’t realize is that these particles don’t just linger—they continuously move between air and surfaces, re-circulating indoors over time.
