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.

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. 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. The HealthPro Plus XE at work next to Leia the cat. Not only did she see a dramatic improvement in the air quality for the kittens, but visitors also noticed the difference. The previously lingering food and litter odors were gone. “I definitely don’t smell that anymore,” Mellissa said. “I’m really impressed.” “The kittens aren’t sneezing anymore. The air purifier has had a huge impact.” When it comes to daily use, Mellissa has found a setup that works perfectly for the rescue’s needs. During cleaning, she runs the fan at its highest setting, ensuring dust and particles are quickly filtered out. For everyday operation, she adjusts the fan to levels 2 or 3, which run quietly enough not to disturb the kittens at night. Looking ahead For Mellissa, clean air ensures a brighter future for Tiny but Mighty Kitten Rescue. She intends to continue providing even more kittens with a safe haven before transitioning to loving homes. The cleaner air and lack of odor in the rescue has already improved adoption visits, a critical step in finding forever homes for the kittens. Mellissa emphasizes her desire to address the root cause of ownerless kittens—unspayed and neutered animals in the population. She hopes to get the word out to more pet owners about the crucial role of spaying and neutering their animals. As she warns, “the cat overpopulation is so crazy here. Spay and neuter your cats, spay and neuter your dogs to help lower those populations.” Conclusion Tiny but Mighty Kitten Rescue’s story underscores the profound difference clean air technology can make in transforming lives—both human and animal. For Mellissa, investing in air purification wasn’t just about solving a nuisance; it was about creating a healthier, more inviting space where kittens could thrive and visitors could feel comfortable. By addressing the often-overlooked issue of air quality, she has set a powerful example for other rescues, shelters, and even individual pet owners facing similar challenges.","

Not only did she see a dramatic improvement in the air quality for the kittens, but visitors also noticed the difference. The previously lingering food and litter odors were gone. “I definitely don’t smell that anymore,” Mellissa said. “I’m really impressed.”

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

When it comes to daily use, Mellissa has found a setup that works perfectly for the rescue’s needs. During cleaning, she runs the fan at its highest setting, ensuring dust and particles are quickly filtered out. For everyday operation, she adjusts the fan to levels 2 or 3, which run quietly enough not to disturb the kittens at night.

Looking ahead

For Mellissa, clean air ensures a brighter future for Tiny but Mighty Kitten Rescue. She intends to continue providing even more kittens with a safe haven before transitioning to loving homes.

The cleaner air and lack of odor in the rescue has already improved adoption visits, a critical step in finding forever homes for the kittens.

Mellissa emphasizes her desire to address the root cause of ownerless kittens—unspayed and neutered animals in the population. She hopes to get the word out to more pet owners about the crucial role of spaying and neutering their animals. As she warns, “the cat overpopulation is so crazy here. Spay and neuter your cats, spay and neuter your dogs to help lower those populations.”

Conclusion

Tiny but Mighty Kitten Rescue’s story underscores the profound difference clean air technology can make in transforming lives—both human and animal.

For Mellissa, investing in air purification wasn’t just about solving a nuisance; it was about creating a healthier, more inviting space where kittens could thrive and visitors could feel comfortable. By addressing the often-overlooked issue of air quality, she has set a powerful example for other rescues, shelters, and even individual pet owners facing similar challenges.

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.

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.”","

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.

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.

Learn more.","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.2The 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: Stratospheric 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. Tropospheric 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 Fever3,4 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. First used in Eastern Europe, speleotherapy consists of spending time in a salt cave, where four environmental conditions are thought to help reduce symptoms of respiratory illness:5 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.

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. First used in Eastern Europe, speleotherapy consists of spending time in a salt cave, where four environmental conditions are thought to help reduce symptoms of respiratory illness:⁵

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

Take the claims with a grain of...well, salt

So here’s the takeaway: We’re not saying you shouldn’t get a Himalayan salt lamp. Their dim glow can be quite soothing at night when you’re trying to fall asleep.

But they don’t purify air. And “air purifiers” that emits ions and ozone may make your indoor air quality worse, introduce new health problems, and exacerbate existing ones.

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.

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.

However, strong winds also can spread fires more quickly, causing larger fires with greater impact. Regional weather can be the dominant determinant in how a fire behaves as well as how smoke affects surrounding areas. However, regional weather systems can spread fires quickly and result in larger fires with more smoke generated, creating the potential for even greater impacts. Strong regional weather systems can also dominate a fire’s behavior for days and be the determining factor of where and how smoke will affect an area. Smoke can travel for miles beyond its source.

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. An air purifier for wildfire smoke, will help remove smoke particles of all sizes down to 0.003 microns from the indoor air and help control ozone levels. 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. The app also tracks up to six key wildfire pollutants, such as PM2.5, CO2, and NO2, so that you have the best picture of your local air quality during a wildfire and can take action to help protect your health. Wildfires are increasing in frequency and intensity. Wildfire smoke can negatively affect your health, even if you’re far away from the actual fire. Learn to protect the health of yourself and your family, and rest assured that you’ve taken the necessary precautions. During a wildfire, it’s also important to monitor your local air quality to see how wildfire smoke will affect your outdoor air. The takeaway Wildfires are increasing in frequency and intensity. Wildfire smoke can negatively affect your health, even if you’re far away from the actual fire. And while wildfire smoke may be a warning sign of imminent fires, smoke also delivers its own set of risks for people living miles beyond the source.

Central Chile faces poor air quality with unhealthy AQI levels. Learn more about affected cities, causes, and when conditions may improve.

","Is the air quality good in Chile? As of June 10, 2026, air quality in central Chile remains poor, with major cities experiencing \"unhealthy\" levels and high PM2.5 concentrations, posing health risks to residents, especially children and the elderly. By 12:30 AM (Chile Standard Time, GMT-4), some urban centers recorded AQI readings between 100 and 200, prompting health warnings. Residents are advised to limit prolonged outdoor activity, wear masks outdoors, keep windows closed, and use air purifiers indoors. While conditions fluctuate throughout the day, central Chile regularly experiences seasonal pollution episodes during the colder months. Studies conducted in Santiago and Temuco have confirmed that for every 50 µg/m³ increase in PM10 levels in 24 hours, there is an average increase of about 3% in general mortality, with increases in PM10 also associated with higher respiratory and cardiovascular mortality (1). Air quality map of central Chile, as of 12:30 AM (local time) on June 10, 2026. Source: IQAir. Which cities are affected by bad air quality in Chile? As of June 10, 2026, several cities in central Chile are experiencing degraded air quality. Some of the affected cities include: Coyhaique Loncoche Osorno For a complete, real-time overview of pollution levels across the region, see Chile's air quality map. When will the air quality improve in Chile? Research shows PM2.5 increases from April through July, then begins to decrease in September and October as spring arrives and atmospheric conditions become more favorable for pollutant dispersal. Mean PM2.5 levels during the cold season from April through September are more than twice as high as those in the warm season from October through March. In the near term, isolated rainfall or stronger winds may offer brief relief (2). Lasting improvement depends on consistent enforcement of restrictions on wood burning and vehicle emissions during pollution alert episodes. What is causing poor air quality in Chile? Firewood produces as much as 94% of fine particulate matter emissions in some Chilean cities according to the Ministry of Environment, with two million homes heated using solid biofuels nationwide, and the firewood market generating an estimated 800 million dollars annually (3). Firewood smoke from residential heating is responsible for more than 90% of PM2.5 emissions in cities located between the O'Higgins and Aysén regions, where indiscriminate use of firewood for heating is the primary driver of seasonal air quality crises (4). In Santiago, the situation is compounded by the city's position between the Andes and the Cordillera de la Costa, which creates a pocket where stagnant air accumulates and disperses slowly, while vehicle exhaust, fossil fuel power generation, and construction dust add a persistent pollution base throughout the year.

Home to millions of residents, five cities stood out as the most polluted major cities in the world for 2025 – find out which ones and why.

","The 2025 World Air Quality Report reveals the persistent global challenge posed by high concentrations of air pollution. Unhealthy air remains a daily reality for residents in some of the world’s most polluted urban centers. Tens of millions of people live in these cities and are exposed to elevated risks of respiratory and cardiovascular conditions over time (1). Many residents in these cities also face economic and social challenges that can compound the effects of long-term exposure to air pollution, challenges that are further compounded by exposure to industrial emissions, vehicular pollution, agricultural burning, and inadequate regulatory enforcement. Air pollution is an unequal burden for these residents, and for particularly vulnerable populations such as children, the elderly, and individuals with pre-existing health conditions, like asthma. 5. Kinshasa, Democratic Republic of the Congo Kinshasa, the capital of the Democratic Republic of the Congo (DRC), ranked fifth among the world’s most polluted major cities in 2025. With an average annual PM2.5 concentration of 50.2 µg/m3, the city’s air quality remains in the hazardous air quality range as it has in prior years, continuing to pose serious health risks to city residents.Air quality in Kinshasa, DRC on April 20, 2026. Source: IQAir. Air pollution in Kinshasa can come from both indoor and outdoor sources. Indoor cooking with wood and charcoal, a common practice in many households, contributes significantly to airborne particulate matter. Forest fires, often linked to agricultural clearing and land management, release clouds of smoke into the atmosphere. Industrial activities and regional agricultural burning also contribute to poor air quality, compounded by limited regulatory oversight and enforcement. One of the biggest challenges to mitigating pollution is the lack of reliable air quality monitoring infrastructure in the DRC. While some monitoring stations exist, the DRC—like much of Africa—lacks the comprehensive networks needed to accurately track pollution levels and inform public health responses. 4. Kolkata, India Kolkata, India, was one of the world’s most polluted urban centers in 2025. With an average annual PM2.5 concentration of 51 µg/m3, it’s the city’s worst average since 2021’s annual average of 59 µg/m3.This change reflects regional trends, where rapid industrialization, vehicular emissions, and seasonal agricultural burning frequently create a haze that lingers over the city for much of the year.

Vehicle emissions, industrial activity, construction dust, and unregulated waste burning add to the burden (2). During the winter months, crop residue burning in neighboring states and across the Indo-Gangetic Plain compounds the problem. 3. Dhaka, Bangladesh Dhaka, the capital of Bangladesh, returned as the world’s third most polluted major city in 2025, with an average annual PM2.5 concentration of 68 µg/m3. While Dhaka has experienced an improvement in average annual PM2.5 over 2024 and 2023 (measuring annual average concentrations of 78 and 80.2 µg/m3 respectively), its air quality remains far above safe levels. Persistent air quality challenges continue to affect residents’ health.

The 2025 World Air Quality Report reveals the persistent global challenge posed by high concentrations of air pollution.

Unhealthy air remains a daily reality for residents in some of the world’s most polluted urban centers. Tens of millions of people live in these cities and are exposed to elevated risks of respiratory and cardiovascular conditions over time (1).

Many residents in these cities also face economic and social challenges that can compound the effects of long-term exposure to air pollution, challenges that are further compounded by exposure to industrial emissions, vehicular pollution, agricultural burning, and inadequate regulatory enforcement. Air pollution is an unequal burden for these residents, and for particularly vulnerable populations such as children, the elderly, and individuals with pre-existing health conditions, like asthma.

5. Kinshasa, Democratic Republic of the Congo

Kinshasa, the capital of the Democratic Republic of the Congo (DRC), ranked fifth among the world’s most polluted major cities in 2025. With an average annual PM2.5 concentration of 50.2 µg/m3, the city’s air quality remains in the hazardous air quality range as it has in prior years, continuing to pose serious health risks to city residents.

Air pollution in Kinshasa can come from both indoor and outdoor sources. Indoor cooking with wood and charcoal, a common practice in many households, contributes significantly to airborne particulate matter. Forest fires, often linked to agricultural clearing and land management, release clouds of smoke into the atmosphere. Industrial activities and regional agricultural burning also contribute to poor air quality, compounded by limited regulatory oversight and enforcement.

One of the biggest challenges to mitigating pollution is the lack of reliable air quality monitoring infrastructure in the DRC. While some monitoring stations exist, the DRC—like much of Africa—lacks the comprehensive networks needed to accurately track pollution levels and inform public health responses.

Discover the most effective place to put your air purifier in the bedroom.

","The best place to put an air purifier in a bedroom is close enough to improve the air you breathe while sleeping, but positioned so clean air can circulate freely throughout the room (1). Because people spend long, uninterrupted hours in bedrooms, air purifier placement can influence how effectively airborne particles and allergens are removed from the sleeping environment. Clean air and the sleeping environment Bedrooms are where people typically spend the longest uninterrupted periods indoors, making them critical spaces for clean air—especially for those with allergies, asthma, or sensitivities to dust, pet dander, or outdoor pollutants. Because people spend extended periods breathing the same indoor air while sleeping, air purifier placement can influence how effectively these particles are removed from the sleeping environment overnight. Reducing indoor pollution sources, improving airflow and ventilation by opening windows when outdoor air quality allows, and using high-efficiency filtration can all influence how particles accumulate indoors. For example, reducing the use of heavily scented products, improving ventilation when outdoor air quality is good, and limiting indoor smoke or dust sources can help reduce the amount of airborne particles circulating through a bedroom. Why airflow matters in a bedroom Air purifiers work by pulling polluted air through a filtration system and recirculating cleaned air back into the room. When airflow is blocked by walls, furniture, or bedding, particles can remain concentrated in parts of the room instead of circulating toward the purifier. Because airflow influences how particles move through a bedroom, purifier placement can affect how efficiently airborne particles are removed from the sleeping environment. Common mistakes to avoid in bedroom purifier placement Many people unknowingly reduce their air purifier’s effectiveness by making these placement errors: In a corner or behind furniture: This blocks airflow and limits the purifier’s reach. Keep it in an open area where air can circulate freely. Too close to electronics or heat sources: Avoid placing it near TVs, lamps, or heating vents, as heat can affect performance or pose a safety risk. Near open windows during high-pollution times: While ventilation is good, outdoor allergens or smog can enter and overwhelm the purifier. Close windows during allergy season, wildfires, or peak traffic hours. Ignoring filter maintenance: A clogged filter reduces airflow and efficiency. Check and replace filters as recommended, especially in high-dust environments. If your bedroom is large or irregularly shaped, consider a purifier with strong airflow or use a second unit to ensure even coverage. For children’s rooms, place the purifier out of reach but where it can still circulate air effectively. Frequently Asked Questions Should I run my air purifier all night in the bedroom? Yes. Running it continuously on a low or night mode ensures clean air throughout your sleep, which is especially beneficial for allergy or asthma sufferers. Most modern purifiers are quiet enough not to disrupt rest. Can I place the air purifier on the floor next to my bed? Yes. Placing an air purifier on the floor near the bed can be effective, provided airflow is not blocked by furniture or bedding. Keep enough space around the purifier for air to circulate freely. How far from the bed should the air purifier be? Aim for 3–6 feet away, positioned so clean air flows toward your breathing zone without blowing directly on you. This balances effectiveness and comfort. Does the air purifier need to be centered in the room? Not necessarily. Prioritize placing it near your bed but with unobstructed airflow. For larger bedrooms, a central location can help, but proximity to your sleeping area is most important. Can I use an air purifier in a small bedroom? Yes. Choose a model sized for your room and place it where airflow isn’t blocked. Even in smaller bedrooms, compact air purifiers can help improve air quality when positioned with unobstructed airflow. Conclusion Air purifier placement can influence how effectively fine particles and allergens are removed from the air you breathe while sleeping. Positioning the purifier where airflow remains unobstructed helps improve circulation and reduce indoor particle buildup over time. Indoor air quality is often managed through a combination of source control, ventilation, and filtration. Combined with regular cleaning and reduced indoor pollution sources, proper air purifier placement can help create a cleaner sleeping environment and improve the air circulating through your breathing zone overnight.","

Have you ever wondered how air purifiers clean the air? Learn the science behind how purifiers capture pollutants.

","Air purifiers are designed to remove harmful airborne pollutants from indoor air, significantly improving air quality and protecting health. Using filtration, air purifiers can reduce exposure to common indoor pollutants—like fine particles (PM2.5), allergens, smoke, some microbes carried on particles, and (with the right media) many odors and gases. Lower exposure can be especially helpful for comfort and day-to-day symptom management for people who are sensitive to airborne irritants. High-efficiency air purifiers can meaningfully reduce indoor particle concentrations in the rooms where they run—especially when they’re properly sized for the space and operated consistently (1). How air purifiers work Mechanical air purifiers draw in polluted air and pass it through a series of filters, each designed to target specific types of contaminants. The purifier doesn’t create “new” air—it repeatedly reduces what’s already in the room by filtering the same air over and over. The more air it moves and the longer it runs, the more it can lower particle levels. Pre-filters capture large particles like dust, pet hair, and lint, extending the life of the main filter. HyperHEPA filters remove greater than 99.5% of airborne particles as small as 0.003 microns. Activated carbon filters absorb gases and odors from sources like cleaning products, paints, and cooking fumes. After filtration, clean air is recirculated into the room, creating a healthier indoor environment. Modern purifiers often include smart sensors to monitor air quality in real time, adjusting fan speeds automatically to maintain optimal conditions. What air purifiers remove from your air Air purifiers using mechanical filtration can remove many airborne pollutants, including: Particulate matter (PM2.5 and PM10): Tiny particles from smoke, vehicle emissions, and industrial pollution. PM2.5 can penetrate deep into the lungs and bloodstream. Allergens: Dust mites, pollen, and pet dander that trigger allergies and asthma. Biological particles: Mold spores and some bacteria, plus virus-containing respiratory aerosols (viruses are typically carried in droplets/aerosols rather than floating “naked” in air). Some gases and odors: Certain VOCs and smells can be reduced with activated carbon or other sorbent media (gas removal depends on the specific chemical and filter design). Microplastic fibers/fragments: These behave like other airborne particles and can be captured by high-efficiency particle filtration; research on health impacts is still evolving. Where and when air purifiers are most effective Air purifiers are especially valuable in: Bedrooms: Running a purifier overnight improves sleep quality by reducing allergens and irritants that disrupt breathing. Living areas and offices: High-traffic spaces benefit from continuous filtration to remove dust, cooking fumes, and outdoor pollution that enters through open windows or on clothing. Homes with vulnerable individuals: People with asthma, allergies, or weakened immune systems see significant symptom relief with consistent air purification. Urban or high-pollution areas: Purifiers mitigate the effects of smog, wildfire smoke, and industrial emissions, particularly when outdoor air quality is poor. What air purifiers don’t do While air purifiers are powerful tools for improving indoor air, they have limitations: They don’t replace ventilation: Fresh air exchange is still essential for diluting indoor pollutants and maintaining humidity levels. They don’t clean surfaces: Purifiers only address airborne particles; regular dusting and vacuuming are needed to remove settled pollutants. They aren’t a cure for underlying health conditions: While they reduce triggers, purifiers should complement—not replace—medical treatments for asthma or allergies. They require maintenance: Filters must be replaced periodically (timing for replacements depend on the model, the filter, and usage) to remain effective. Best practices for using an air purifier For best results, size your air purifier to match your room and run it continuously, especially in high-traffic or high-pollution areas like bedrooms. Choose the right size: Select a purifier rated for your room’s square footage to ensure adequate air turnover. Run it continuously: For best results, keep the purifier on 24/7, especially in bedrooms or areas with high pollutant levels. Place it strategically: Position the unit where air can circulate freely, not blocked by furniture or walls. Close windows and doors: During high-pollution events (e.g., wildfires), seal the room to prevent outdoor contaminants from entering. Monitor air quality: Use built-in sensors or a separate monitor to track PM2.5, VOCs, and humidity, adjusting settings as needed. When comparing models, CADR can help you estimate how quickly a purifier can reduce particles in a room, but it doesn’t tell you how well performance holds up over time. For long-term effectiveness, consider metrics and testing that reflect durability, such as CCM, and follow the manufacturer’s maintenance guidance. Frequently Asked Questions Do air purifiers help with odors? Yes. Activated carbon filters effectively absorb odors from cooking, pets, smoke, and chemicals, leaving the air fresher. Can air purifiers remove viruses like COVID-19? HyperHEPA (and HEPA) filters can help reduce airborne virus-containing aerosols by trapping the particles that carry them. Air cleaning should still be used alongside ventilation and hygiene practices. Are air purifiers safe to run all night? Yes.

Air purifiers are designed to remove harmful airborne pollutants from indoor air, significantly improving air quality and protecting health.

Using filtration, air purifiers can reduce exposure to common indoor pollutants—like fine particles (PM2.5), allergens, smoke, some microbes carried on particles, and (with the right media) many odors and gases. Lower exposure can be especially helpful for comfort and day-to-day symptom management for people who are sensitive to airborne irritants.

High-efficiency air purifiers can meaningfully reduce indoor particle concentrations in the rooms where they run—especially when they’re properly sized for the space and operated consistently (1).

Hawaii’s worst flooding in 20 years has heavily impacted several islands. Learn more about the flooding.

","What is the location of the flooding? As of April 9, 2026, Hawaii is experiencing renewed flooding threats from a multi-day Kona storm impacting the entire state. This ongoing flooding event follows devastating March floods and is driven by prolonged heavy rainfall, saturated ground conditions, and storm systems pulling moisture from the Pacific (1). The most impacted areas include Oahu’s North Shore, particularly Waialua and surrounding communities near the Kaukonahua Stream, where debris removal and flood prevention efforts are underway. Additional risks extend across Maui, the Big Island, and Kauai due to statewide flood watches and continued rainfall (2). Geographically, low-lying coastal regions, stream-adjacent communities, and previously flooded zones remain highly vulnerable, especially near waterways such as the Kaukonahua Stream and areas downstream of the Wahiawa Dam. Which cities or areas are affected by the flooding? Several islands and regions of Hawaii were impacted by the flooding, including: Haleʻiwa Honolulu Kahului Kāne‘ohe Kauai (island-wide risk) Kula Makaha Valley Mānoa Mokuleia Puna District (Big Island) Waialua Wahiawa Wai‘anae Flooding impacts include road closures, water entering homes, overflowing streams, and localized flash flooding across multiple islands (3). What is the current containment status of the flooding? As of April 9, 2026, flooding is not fully contained, and conditions remain dynamic as additional rainfall continues across Hawaii. Emergency crews are actively working to mitigate risks by clearing streams, storm drains, and debris in flood-prone areas such as Waialua and Oahu’s North Shore. Authorities report that while preventive measures are ongoing, saturated soil conditions significantly increase the likelihood of rapid flooding. Flash flood warnings and additional alerts are expected as storm bands persist through the week (4). Are there any evacuation orders or alerts in place? Flood watches are currently in effect for the entire state of Hawaii, with officials warning residents to be prepared for possible evacuations as conditions worsen. Emergency shelters have been activated across Oahu as a precaution. Designated shelter locations include: Wai‘anae District Park Mānoa Valley District Park Kāne‘ohe District Park George Fred Wright Wahiawa District Park Authorities advise residents to stay alert, avoid floodwaters, and follow official evacuation instructions if issued. Emergency response teams and Red Cross personnel are on standby to assist affected communities. How can I protect myself from mold after flooding? It’s important to take steps to prevent mold after a flood. Before entering a flooded area, make sure it is safe and free from electrical hazards or structural damage. Use protective gear: wear gloves, goggles, and a KN95/FFP2 mask to minimize exposure to mold spores. If there is still standing water, remove it as quickly as possible. Use pumps, wet-dry vacuums, or buckets to extract the water. Open windows and doors to facilitate air circulation and use fans, dehumidifiers, and HVAC systems to help dry the space. This step is crucial within the first 24-48 hours after flooding to prevent mold growth. Remove and discard any items that have been severely damaged by floodwater and cannot be thoroughly cleaned and dried. This includes carpets, upholstered furniture, mattresses, and any other porous materials. Thoroughly clean all hard surfaces with a detergent or cleaner suitable for mold remediation. Use a solution of 1.5 cups of bleach mixed with one gallon of water to disinfect nonporous surfaces. Never mix bleach with ammonia or other cleaning products, as the fumes are toxic. Maintain an indoor relative humidity (RH) of 35-50%. High humidity promotes mold growth, so consider using dehumidifiers in damp areas. Run a high-performance air purifier for mold, both during and after the mold removal work. If the flooding and mold damage are extensive, consider contacting professionals specializing in mold remediation to ensure proper cleanup and restoration. Remember, mold can pose health risks, so it's important to take these steps promptly and thoroughly.

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.

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

\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.

Find out whether running an air purifier all day is necessary, safe, and worth it for cleaner indoor air.

","In most cases, yes. If your goal is to reduce all and any exposure to air pollution, running an air purifier throughout the day is the most effective approach. That’s because indoor air pollution is not a one-time event. Dust settles and gets stirred up again, cooking releases particles and gases, outdoor pollution seeps indoors, and people and pets continuously add new pollutants to the air. Running your air purifier continuously is one of the most effective ways to reduce many common airborne pollutants, including dust, allergens, smoke particles, some airborne microbes carried in droplets or aerosols, and—if the purifier includes the right gas-phase media—certain odors and VOCs. Modern air purifiers are generally designed for continuous operation. Many models also include quieter settings, automatic modes, or smart sensors that help balance air cleaning with energy use and noise. Why continuous operation is best for air quality Indoor air can contain higher concentrations of pollutants than outdoor air, due to poor ventilation, off-gassing from furniture and cleaning products, pet dander, and outdoor pollution seeping indoors. Even after you clean a room once, new pollutants keep entering and forming—so turning a purifier off for long stretches often means you’re letting the room “reload.” Unlike intermittent use, which allows pollutants to accumulate between cycles, all-day operation ensures that contaminants like PM2.5 – particulate matter measuring 2.5 microns in diameter or smaller – are constantly filtered out, providing consistent protection. This is especially true in urban areas, near busy roads, or during wildfire and high-pollution events. Energy, noise, and maintenance considerations Running an air purifier all day does use electricity, but many modern units are designed to do so efficiently—especially on lower or auto settings. In real life, operating cost depends on the model, fan speed, and how many hours per day it runs. Noise also matters. Most high-quality purifiers are quiet enough for everyday use on lower settings, which is why many people run them continuously in bedrooms, living rooms, and home offices. During smoke events or high-pollution periods, a higher fan speed may be worth the extra sound because it helps reduce particle levels more quickly. Continuous use can also mean filters load faster. That’s normal. The tradeoff is straightforward: more run time usually means cleaner air, but also more consistent maintenance. The best approach is to follow the manufacturer’s replacement guidance or filter-life indicator rather than guessing. When you might adjust your approach While all-day use is ideal, there are a few scenarios where you might adjust: Low-pollution periods: If outdoor air quality is excellent and your home is well-ventilated, you can run the purifier intermittently or use an automated mode to conserve energy. Unoccupied rooms: If a room is rarely used, you can turn the purifier off or set it to a lower fan speed. Budget constraints: If energy use is a concern, prioritize the rooms where you spend the most time—especially bedrooms and main living spaces—and use lower or automatic settings when pollution levels are lower. Best practices for all-day air purifier use For best results, place your air purifier where air can move freely around it and avoid blocking it with furniture or walls. In bedrooms, many people prefer to place the unit a few feet from the bed, so the airflow isn’t directed straight at them. If your air purifier has an automatic or smart mode, use it. These settings can raise fan speed when pollution increases and lower it when air is cleaner, helping balance performance, noise, and energy use. During wildfire smoke or heavy outdoor pollution, keep windows and doors closed so you’re not constantly pulling new contaminants into the room. And to maintain performance over time, replace filters according to the manufacturer’s guidance or the system’s filter-life indicator. Frequently Asked Questions Is it safe to run an air purifier all day?Yes, most modern filtration-based air purifiers are designed for continuous operation. Choose a model that does not intentionally generate ozone, keep airflow unobstructed, and follow routine maintenance guidance to keep performance steady. Will running an air purifier all day increase my electricity bill?The impact is usually minimal. Energy-efficient air purifiers often cost only a few dollars per month to run continuously, and automatic or smart modes can further reduce energy use by lowering fan speed as needed. Can I run an air purifier in my bedroom overnight?Yes. Many people run air purifiers overnight, often on a lower or quieter setting. Place the unit a few feet from the bed to avoid direct airflow and minimize noise disruption. Do I need to run an air purifier if I have good ventilation?Even with good ventilation, indoor air can still contain pollutants from cooking, cleaning, pets, and outdoor sources. An air purifier adds an extra layer of protection, especially in urban or high-traffic areas. Conclusion If you want your indoor air to stay cleaner, it usually makes sense to leave your air purifier on throughout the day. Indoor pollution is constantly entering, forming, and being stirred back into the air—even when a room looks clean. For most households, the best strategy is simple: run the purifier consistently, place it well, maintain the filters, and increase fan speed during smoke, traffic, or other high-pollution periods.

Learn how much electricity an air purifier uses, what affects energy consumption, and how to keep indoor air clean efficiently.

","Many people assume that running an air purifier all day must use a lot of electricity. After all, it is an appliance designed to run for hours at a time—sometimes around the clock. But in most cases, air purifiers use surprisingly little power, especially compared to the appliances households already use every day. Even when operating continuously, a well-designed air purifier typically uses far less electricity than a refrigerator, washing machine, or toaster (1)(2)(3). That makes energy use less of a barrier than many people expect. A 50-watt air purifier running 24/7 uses about 1.2 kilowatt-hours (kWh) per day, or roughly 438 kWh per year. At an electricity rate of about $0.17 per kWh, that comes out to less than $75 annually. Many efficient models use even less power on lower settings. For example, IQAir’s Atem X air purifier uses between 6 and 86 watts depending on fan speed, while the Atem Earth can use as little as 4 watts on a low setting. In other words, the cost of continuous air cleaning is often modest—especially when the unit is used thoughtfully and matched to the space. In many homes, the bigger misconception is not that air purifiers use no electricity, but that running them continuously must be expensive. In practice, their energy demand is often far lower than people expect. What affects how much electricity an air purifier uses Not every air purifier uses the same amount of electricity all the time. Actual energy use depends on a few practical factors: fan speed, room conditions, how often the purifier runs, and whether the unit adjusts automatically to the air. In general, fan speed has the biggest impact. Lower speeds use less electricity and are often well suited for overnight or background use. Medium settings tend to offer a good balance between cleaning performance and energy efficiency for everyday operation. High or maximum speeds use more electricity, but they are usually intended for shorter periods—such as during wildfire smoke events, cooking pollution, or high-allergen days. Auto mode can also improve efficiency. When an air purifier uses sensors to respond to real-time air quality, it can increase airflow when pollution rises and reduce it when the air is cleaner. That helps avoid running at a high setting when it is not needed. Proper sizing and maintenance matter too. A purifier that is appropriately sized for the room can clean the air more efficiently than an undersized unit working too hard to keep up. Clean, properly maintained filters also help the system operate as intended. Replacing filters on time supports both cleaning performance and efficient operation. How air purifiers compare with other household appliances One of the clearest ways to understand air purifier electricity use is to compare it with appliances households already run every day. That comparison helps separate the idea of continuous operation from the reality of relatively low wattage. Air purifiers are typically among the least energy-intensive appliances in a home. A refrigerator runs continuously and generally uses far more electricity over the course of a year. Washing machines draw hundreds of watts per cycle. Even a toaster can use far more power during a few minutes of use than an air purifier uses in an hour on a lower setting. That comparison helps put the concern in perspective: an air purifier may run for long periods, but it usually does so at relatively low wattage. Continuous use sounds energy-intensive, yet in practice the electrical demand is often modest. For households looking to reduce both indoor air pollution and unnecessary energy use, efficiency features can make a difference. ENERGY STAR-certified air purifiers are designed to meet stricter efficiency criteria, and smart operating modes can help reduce unnecessary power consumption without sacrificing day-to-day air cleaning. How to keep air cleaning efficient For most households, efficient air cleaning does not mean running an air purifier less. It means using the right settings, the right size unit, and the right maintenance habits to keep performance high and energy use modest. A few simple habits can help: Use auto mode when available so the purifier responds to changing air conditions automatically. Match the air purifier to the size of the room so it can clean effectively without overworking. Use higher fan speeds strategically during smoke events, cooking, or other short-term pollution spikes. Replace filters on time so airflow and performance remain consistent. Keep doors and windows closed during high-pollution events to reduce the amount of outdoor pollution entering the space. The goal is not simply to use less electricity. It is to maintain cleaner indoor air as efficiently and consistently as possible. Frequently Asked Questions How much does it cost to run an air purifier 24/7? That depends on the purifier’s wattage, fan speed, and local electricity rates. But in many cases, the cost is relatively low. A 50-watt air purifier running continuously uses about 1.2 kWh per day, which typically translates to only a few dollars per month.

Learn the difference between various air purifier types and how they work – or don’t work – to clean the air.

","Air purifiers are designed to clean indoor air—but how they do it, and how effectively they work, can vary significantly depending on the technology used. At a basic level, most air purifiers draw air into the system, pass it through one or more filters, and then recirculate cleaner air back into the room. But the type of filtration—and how it interacts with different pollutants—determines what is actually removed from the air.

Air purifiers are designed to clean indoor air—but how they do it, and how effectively they work, can vary significantly depending on the technology used.

At a basic level, most air purifiers draw air into the system, pass it through one or more filters, and then recirculate cleaner air back into the room. But the type of filtration—and how it interacts with different pollutants—determines what is actually removed from the air.

Understanding these differences can make it easier to identify which systems are designed for comprehensive air cleaning—and which rely on more limited or situational technologies.

","When choosing an air purifier, one of the first numbers people encounter is CADR—but it is also one of the most misunderstood. CADR, or Clean Air Delivery Rate, measures how quickly an air purifier can clean the air in a space.

What CADR actually measures CADR reflects how quickly an air purifier removes particles from the air. It combines airflow and filter efficiency to estimate how fast clean air is delivered within a given space. In practical terms, this means CADR indicates how quickly airborne particles can be cleared—but not how consistently that performance will hold over time. CADR measures the removal rate of airborne particles as small as 0.09 microns to as large as 11 microns (1)(2). It reflects how filter efficiency and airflow interact within a given space, but is limited to measuring performance speed rather than long-term usage. CADR is often presented alongside CCM, but the two metrics reflect very different aspects of performance. CADR focuses on how quickly clean air is delivered, while CCM indicates how much pollution a system can handle before its performance begins to decline. The limitation of CADR: Speed vs long-term performance While CADR is commonly used to compare how quickly an air purifier works, it does not indicate how performance will hold over time.

Find out today whether investing in an air purifier can help you control household dust in your home.

","Yes, air purifiers effectively remove household dust from indoor air (1). Dust is a common indoor pollutant composed of tiny particles like skin cells, fabric fibers, pet dander, pollen, and even microscopic debris from insects or outdoor sources. High-quality air purifiers, especially those with HEPA or HyperHEPA filtration, are designed to capture these particles as small as 0.3 microns—or even 0.003 microns with advanced HyperHEPA technology—significantly reducing dust levels in your home. By continuously cycling air through their filters, purifiers trap and remove dust, preventing it from settling on surfaces or being inhaled, which can aggravate allergies, asthma, and other respiratory issues. Why dust is an ongoing indoor air problem Dust is not a one-time issue—it is continuously generated indoors. Everyday activities such as walking, cleaning, and even sitting on furniture can reintroduce dust particles into the air, where they remain suspended before settling again. Because dust cycles between air and surfaces, reducing it requires addressing both airborne particles and what accumulates over time. How air purifiers capture household dust Air purifiers use a combination of filtration technologies to target dust particles. The primary defense is the HyperHEPA filter, which physically traps dust as air passes through a dense network of fibers. HyperHEPA filters are certified to remove 99.97% of particles as small as 0.003 microns, including most household dust. Many air purifiers also include a pre-filter, which captures larger dust particles, hair, and lint before they reach the main filter. This not only extends the life of the HEPA filter but also improves overall efficiency. Some models add activated carbon filters to address odors or volatile organic compounds (VOCs) that may accompany dust, though carbon alone doesn’t target dust directly. Together, these layers ensure that dust—whether visible or microscopic—is continuously removed from the air. Much of the dust people see on surfaces was once suspended in the air. Air purifiers help reduce this cycle by capturing particles before they settle—slowing how quickly dust accumulates over time. How air purifiers reduce dust in real-world conditions Air purifiers are effective at removing airborne dust, but they do not eliminate dust entirely. Dust that has already settled on surfaces, embedded in fabrics, or trapped in carpets requires physical cleaning. For this reason, air purification is most effective when combined with regular cleaning and ventilation, helping reduce the amount of dust circulating in the air over time. Why dust continues to circulate indoors While air purifiers excel at removing airborne dust, they can’t eliminate dust entirely because it’s constantly being generated. Common sources include: Fabrics and textiles: Bedding, curtains, upholstery, and clothing shed fibers daily. Pet dander and hair: Pets contribute significantly to dust buildup, especially in homes with carpets or rugs. Outdoor air: Pollen, soil, and pollution enter through open windows, shoes, or ventilation systems. Human activity: Skin cells, hair, and even dead insects add to indoor dust. To maximize the effectiveness of your air purifier in reducing dust, pair it with a consistent cleaning routine. Start by vacuuming carpets, rugs, and upholstery weekly using a HEPA-filtered vacuum, which prevents dust from being kicked back into the air. When dusting surfaces, opt for a damp or microfiber cloth to trap particles rather than scattering them. Regularly washing bedding, curtains, and pet beds in hot water also helps eliminate dust mites and accumulated debris. Simple habits like placing doormats at entryways and removing shoes indoors can significantly cut down on outdoor dust being tracked inside. By addressing both airborne and settled dust, you create a cleaner, healthier environment with less reliance on constant cleaning. Why filtration performance matters over time Air purifiers do not just need to remove dust—they need to continue doing so as filters collect particles. Over time, filters can load with dust, which may affect airflow and performance. Systems designed for long-term efficiency help maintain consistent dust reduction rather than short-term improvement. Frequently Asked Questions Can an air purifier eliminate all dust in my home? No air purifier can remove 100% of dust, since it’s constantly generated. However, a high-quality purifier with HyperHEPA filtration can dramatically reduce airborne dust, making your home cleaner and easing allergy or asthma symptoms. Where should I place my air purifier to best capture dust? Position the purifier in high-traffic areas or rooms where dust accumulates most, such as bedrooms or living rooms. Place it a few feet off the ground (e.g., on a table or stand) for optimal air circulation and avoid blocking the airflow with furniture. How often should I replace the filters if I’m targeting household dust? HyperHEPA filters typically last 36–48 months under normal use, but homes with high dust levels (e.g., pets, carpets, or outdoor pollution) may require more frequent filter replacement. Monitor your filter condition regularly. Do air purifiers help with dust mites? Yes. While air purifiers don’t kill dust mites, they capture dust mite feces and debris, which are major allergens. For best results, use a HyperHEPA purifier in bedrooms and wash bedding weekly in hot water to reduce dust mite populations. Can an air purifier reduce dust on my furniture? Air purifiers primarily target airborne dust, but by reducing the amount of dust circulating in the air, they slow the rate of dust settling on surfaces. Regular dusting and vacuuming are still necessary to keep furniture clean.

Discover how air purifiers help with allergies. Learn about filtration technologies, selecting the right purifier, and managing allergy symptoms effectively.

","Yes. Air purifiers can help reduce airborne allergens—but how much they help depends on how they work and what they are designed to remove. Many people seek relief from allergies by turning to air purifiers—but their effectiveness depends on how they work and what they are designed to remove. Understanding Allergies Allergies occur when the immune system reacts to otherwise harmless substances, such as pollen, dust mites, mold spores, or pet dander. These allergens are often airborne, which is why air quality plays a role in symptom management. The role of air purifiers Air purifiers are designed to eliminate airborne pollutants and contaminants from the air, including allergens. By capturing and trapping allergenic particles, air purifiers aim to create a cleaner and healthier indoor environment, reducing exposure to allergens and alleviating allergy symptoms.

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. Fine particles from outdoor pollution and everyday indoor activities can build up over time, remaining suspended in the air long after they are produced. Reducing indoor exposure often depends on a combination of source control, ventilation, and high-efficiency filtration.
