Learn about Permian Health's innovative approach to improving air quality in Gambia, using cutting-edge technology to reveal invisible pollutants and safeguard public health.

","In the slender West African nation of Gambia, Dr. Sunkaru Touray of Permian Health Lung Institute is leading an unprecedented initiative to illuminate the invisible dangers of air pollution through the strategic deployment of low-cost air quality monitors. A vision born from necessity Dr. Touray, a pulmonologist and critical care physician originally from Kartong, The Gambia, was profoundly affected by the respiratory issues he encountered while practicing in New Mexico. These issues, often linked to hydrocarbon exposure and environmental pollutants, spurred him to address similar problems in Gambia, where air quality data is scarce. \"There's a significant data gap in Africa when it comes to understanding our air,\" Dr. Touray noted. Recognizing the parallels between New Mexico and Gambia, Dr. Touray envisioned the Permian Health Clean Air Initiative. This initiative aims not only to collect data but to empower Gambians with knowledge, enabling them to make informed decisions about their health and advocate for cleaner air. “There’s a significant data gap in Africa when it comes to understanding our air.”–Dr. Sunkaru Touray, Founder, Permian Health The journey of Permian Health Permian Health's mission is clear: to democratize access to air quality data in Gambia by installing low-cost air quality monitors throughout the country. The team selected IQAir’s AirVisual outdoor monitors for this critical work. “These devices are proven to be reliable, user-friendly, and can operate on solar power,” Dr. Touray said. “They also have 4G LTE connectivity,” which make the monitors ideally suited for Gambia's diverse environments—from the bustling streets of Banjul to the rural countryside. \"The goal,\" Dr. Touray explained, \"is not just to collect data but to empower our communities with knowledge so they can make informed decisions about their health and advocate for cleaner air.\" Highlighting areas of concern: Brikama’s air quality Brikama stands as a poignant example of the challenges faced across Gambia. Known for its bustling markets and as a hub for both commerce and community life, the town also grapples with air quality issues that pose risks to its residents. By placing monitors in strategic locations, including the busy highway through Brikama, Permian Health is mapping pollution levels and raising awareness among the local population about the air they breathe daily—while simultaneously acting as a testament to the potential of grassroots air monitoring networks in challenging regions. Dr Touray said, \"As we look to the future, the lessons learned from Brikama will inform our expansion strategies to other regions facing similar challenges. Our success in achieving nationwide coverage, with Brikama as a keystone in our network, exemplifies the scalable model of Permian Health Clean Air Initiative.” “The goal is not to just collect the data but to empower our communities with knowledge so they can make informed decisions about their health.” Local feedback has been largely positive. According to Dr. Touray, real-time access to air quality monitor information has improved local understanding of the dangers of poor air quality, especially during the dry, dusty Harmattan season typically experienced from November to March. Permian Health has collaborated with local groups such as the Brikama Nema Diaspora Group (BRIND) and Karamie’s Health clinic to install sensors in key areas, allowing residents and medical professionals to access real-time air quality data. Pioneering work on the ground To date, the Permian Health air quality network has grown to 14 sensors, achieving nationwide coverage with an air quality sensor in all regions of The Gambia—proof of the project's rapid scalability and success. The project has successfully installed air quality monitors in various locations, including urban areas and industrial sites. These monitors provide real-time data on pollutants like PM2.5, which pose the greatest threat to human health, offering invaluable insights into the air pollution across different regions of Gambia. \"We have sensors in the most densely populated areas,” Dr. Touray said. \"Through the process of collecting PM 2.5 data in Gambia and identifying pollution hotspots, we educate the public about air quality and its impact on public health—and also communicate the importance of installing air quality sensors as a means to make a change.\" This foundational work sets the stage for enhanced accuracy and credibility in air quality monitoring, as underscored by a pivotal development in the project's journey. “The recent addition of a reference-grade monitor donated by MetOne marks a significant leap in our capacity for precision and validation of the data collected by our existing sensor network,” Dr. Touray said. However, maintaining and expanding the network can be impeded by dust accumulation on solar panels during the Harmattan season, unreliable power supplies, and other issues. ‘While we have made significant progress in addressing some of these challenges, connectivity and maintenance in remote areas remain ongoing hurdles in our efforts to maintain and expand the sensor network efficiently,’ Dr. Touray explained. Uniting minds and garnering accolades To raise awareness about their work, Permian Health has created a promotional video which serves as a powerful tool to inform and engage the public about their project. A key milestone for the project was the establishment of the first air quality conference in Gambia, bringing together stakeholders from the government, academia, and civil society to discuss the findings and implications of the collected data. \"This conference was a pivotal moment for us, marking the beginning of a national conversation on air quality,\" reflects Dr. Touray. This national conversation is already making a policy impact. The Ministry of Health has issued public health advisories several times since the air quality sensors were deployed, raising air quality awareness in communities around the country. Dr. Touray emphasizes the importance of partnering with the Gambian government to leverage their data for national air quality standards and planning. \"Working closely with governmental bodies is crucial for our success,\" Dr. Touray notes, highlighting his strong connections within the National Environment Agency, which have been supportive of their endeavors. With the NEA, Permian Health was able to release their first air quality report based on initial installations. This sets the table for future updates from newly installed sensors. Additionally, the project's recent recognition by the Energy Policy Institute of the University of Chicago with an Air Quality Award highlights the global acknowledgment of their impactful work. This prestigious award will enable Permian Health to scale their network further. Currently, there are 22 low-cost sensors deployed, and Gambia will, for the first time ever, have a reference monitor to assist in enhancing air quality monitoring and assessment. Hopes for the Future Thanks to their recent Air Quality Award, Permian Health acquired an 10 sensors, bringing the total to 26 sensors across The Gambia. Six new sensors have been deployed to NEA headquarters, two major health centers with support from the Ministry of Health, and in housing developments in partnership with Gambia’s largest real estate company, TAF Africa Global. The remaining sensors will be deployed to the National Stadium, Gambia International Airport, the Seaport in Banjul, and a major intersection as soon as final government approvals are processed. Dr. Touray envisions a future where every Gambian has access to air quality information, enabling them to protect themselves and their families from air pollution. Furthermore, he hopes to leverage the data collected to advocate for stronger environmental policies and regulations in Gambia. “We’re not just collecting data for the sake of it. We want to drive change.” \"We're not just collecting data for the sake of it. We want to drive change,\" says Dr. Touray. \"Our ultimate goal is for Gambia to set national air quality standards, informed by the comprehensive data we've gathered.\" A key step toward this goal is the second Clean Air Conference, which Permian Health is organizing in partnership with the NEA. The event will bring together stakeholders, including officials from the ministries of Health, Environment, Transport, and Education, to develop a national air quality work plan. According to Dr. Touray, Permian Health is conducting an inventory assessment to determine the key sources of pollution, such as waste burning, reliance on charcoal and firewood for cooking, and transport-related emissions. \"Looking ahead, we aim to strengthen our collaboration with the NEA and the Ministry of Health, to expand and maintain our sensor network.\" \"We plan to enhance public awareness campaigns, especially during high-risk periods, to better inform the community about air quality concerns. We would also like to engage more with local TV stations for them to display air quality and weather information from our network. The takeaway Dr. Sunkaru Touray's work with Permian Health exemplifies innovative activism. The project not only addresses air quality data gaps but also empowers communities to tackle air pollution—an issue that transcends borders. Dr. Touray's mission goes beyond monitoring; it's about transforming the fabric of public health through the lens of air quality.","

","In Pakistan, where vast horizons stretch beneath seemingly clear skies, severe air pollution silently impacts public health and well-being nationwide. Yet, due to a dire lack of data and awareness, the scale of the threat remains largely unseen. 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 15 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.” Pakistan's Air Quality Challenge 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. Rolling Out Pakistan’s Air Quality Network WWF-Pakistan’s initiative, which involves installing a total of air quality sensors in 15 key cities across the country, marks a critical step in Pakistan’s battle against air pollution. All 15 stations are currently up and running. 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. Air Quality Data in Action With the sensors online and data flowing into the IQAir platform, WWF-Pakistan's live contributor profile showcases the impact of their work, allowing anyone to monitor air quality in real-time. This transparency empowers citizens and policymakers alike to take informed action, using reliable data to drive meaningful change across the country. Explore WWF-Pakistan’s profile to see the live data from their monitoring stations across Pakistan. \"Data isn’t just a tool for awareness—it’s the foundation for meaningful action,\" Nazifa Butt, Director Climate Action and Sustainability WWF-Pakistan emphasized. “Now that we have the data, we have something to report and base our decisions on.” Nazifa emphasized the importance of storytelling. “We’re going to have to tell two parts of the story,” she explained, pointing out how data can not only expose alarming trends but also inspire communities to push for change—through policies, advocacy, and local initiatives. Vision For the Future WWF-Pakistan envisions a future where every region of the country has access to real-time, accurate air quality data. \"Each sensor we deploy is a step closer to a healthier, more sustainable Pakistan,\" Nazifa explained. By providing access to this data, WWF-Pakistan aims to foster a culture of proactive health management, where individuals and communities can take the steps necessary to protect themselves from pollution. The air quality data being gathered is more than just numbers—it’s a lifeline for communities struggling with the dangers of polluted air. “Our initiative is laying the foundation for a National Clean Air Research Centre,\" Huzaifa said. \"This will be a hub for research and data-driven policies, enabling us to tackle pollution with innovative strategies.\" “Each sensor we deploy is a step closer to a healthier, more sustainable Pakistan.” Beyond their air quality monitoring project, the WWF-Pakistan team oversees more than 70 active environmental protection initiatives in FY 2024 across the country, ranging from clean water access and forest preservation to sustainable infrastructure development.

Discover how Tedy Mwendwa's air quality monitoring project in Nairobi is bridging critical gaps in Africa's air quality data. Learn more.

","“Every day, I witness the severe impact of poor air quality on my community,” Tedy Mwendwa explained. “Using my expertise in electrical engineering, I felt compelled to create change.” In the heart of Africa, amidst bustling cities and vibrant rural landscapes, Mwendwa is pioneering a movement for cleaner air in Kenya. With a professional foundation in electrical engineering and a passion for environmental stewardship, Mwendwa's deployment of a low-cost air quality sensor in Kenya’s capital city, Nairobi, marks a pivotal step in revealing and addressing pollution and bridging critical gaps in Africa’s air quality data. Nairobi's leap towards cleaner air In late 2021, Mwendwa established an air quality station. Set up along one of Nairobi’s busy thoroughfares, the station gathers data on pollutants from sources like vehicular exhaust and biomass burning. \"It's about leveraging technology to unveil the hidden dangers of pollution.” “It's about leveraging technology to unveil the hidden dangers of pollution,” Mwendwa said. “Empowering our community with this data is crucial for driving action and advocating for sustainable solutions. Without data, we remain in the dark.” Local expertise, global resources drive innovation Building on the foundation of community-driven air monitoring, the project has taken a step forward. It now hosts East Africa’s first Monster Aerosol System (a platform that houses advanced aerosol analyzers), featuring a Time-of-Flight Aerosol Chemical Speciation Monitor (TOF-ACSM). This technology provides real-time, high-resolution data on airborne particles—including nitrates, ammonium, and chlorides—uncovering the chemical fingerprints of pollution with unprecedented precision. Paired with a black carbon monitor, the system offers a comprehensive view of airborne composition and sources. These reference-grade instruments build on the project’s original IQAir AirVisual Outdoor monitor—pairing community-level, real-time data with laboratory-grade chemical insight. The TOF-ACSM will help identify pollution sources—from mineral dust kicked up by unpaved roads and construction to organic aerosols tied to biomass burning and traffic emissions. It will also track seasonal and daily shifts in air quality, influenced by weather patterns and human activity. The initiative is expanding further with the deployment of GRIMM EDM 180 reference monitors across Nairobi, replacing older equipment to deliver faster, more accurate readings with minimal maintenance. In collaboration with the Kenya National Highways Authority (KENHA), these monitors will be placed along major highways and construction zones, ensuring data reflects the realities of urban life. These advancements are part of the NBO-CHEM Project (Nairobi Aerosol Chemistry and Monitoring Initiative), an effort funded by the U.S. National Science Foundation (NSF) and led by Prof. Daniel M. Westervelt, Dr. Godwin Opinde, and Tedy Mwendwa. By combining local expertise with state-of-the-art scientific resources, the project aims to transform how we understand air pollution in East Africa. The challenge of air quality monitoring in Africa The new additions to the project are heartening developments towards advancing air quality understanding in East Africa. Yet, despite the increasing efforts to monitor air quality globally, Africa remains one of the most underrepresented continents in terms of air quality data. According to the 2024 World Air Quality Report, there is only one monitoring station for every 3.7 million people. While coverage has expanded to include more African countries in recent years, there are still vast areas without sufficient data. For example, countries like Niger and Sudan remain without publicly available monitoring data.Air pollution is a major health threat, causing an estimated seven million premature deaths worldwide each year. Without accurate data, it is challenging to address the sources and impacts of air pollution effectively. Grassroots efforts like Mwendwa's are crucial in filling these data gaps, providing models for further projects and inspiring broader initiatives. Harnessing technology for a healthier tomorrow Utilizing an AirVisual Outdoor air quality monitor, Mwendwa’s station gathers critical real-time data. “The AirVisual sensor was easy to deploy and requires little maintenance, even in our somewhat extreme conditions with limited resources,” he said.The project, though small, is already making a difference in the community. “By sharing a link to the AirVisual Platform and using the app, we can easily get our data to students nationwide, enabling them to conduct their own research on pollution,” he said. The data has also been used to inform parents with small children of the effects of poor air quality. \"They need to understand that this data can help give them a better life,\" Mwendwa said. Cultivating environmental consciousness Mwendwa envisions a future where air quality stations span Africa, fostering a culture of environmental awareness and proactive health management. “The data my station is gathering empowers students to conduct community research, highlighting pollution's impact and fostering greater understanding,” he said. “This awareness can significantly influence the general population.\"Mwendwa plans further collaborations with local governments, communities, and international bodies, with this initial project laying a foundation for sustainable environmental policies and practices. “Our goal is to illuminate the unseen threats of pollution through technology,” he said. “Providing our community, and beyond, with this data, equips them to advocate for sustainable solutions essential for a healthier future.

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 fragrancesAnother 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 Cored wicksMany candles have cored wicks made from cotton that are wrapped around a metal support. The design helps keep the wick from falling over into the wax. This is especially useful for scented candles because the fragrance oils soften the wax and allow non-cored wicks to go limp.Are candles toxic? If they have lead in them, possibly. Lead was once commonly used in cored candlewicks — especially in candles imported from overseas. However, after determining that these wicks could present a lead poisoning hazard to young children, the U.S. Consumer Product Safety Commission banned the manufacture and sale of all candles with lead-core wicks in 2003 (8). Zinc and tin have been used as a substitute since the ban.All metal-core wicks release trace amounts of heavy metals into the air when they are burned.However, all metal-core wicks release trace amounts of heavy metals into the air when they are burned. Wicks with zinc and tin cores can still release small amounts of lead particles (9,10).Safer alternativesTo 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: Use essential oils for fragrance.Essential oils can be placed in a diffuser or in bathwater to create a desired aroma. Simmer spices.Place spices such as cinnamon sticks, cloves, and nutmeg in a pot of water and let it simmer on the stove. Create 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 takeawayLighting 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.","

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.

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

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

Cored wicks

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

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

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

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

Safer alternatives

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

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

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

The takeaway

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

Himalayan salt lamps DO NOT purify indoor air.

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

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

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

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

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

Why are Himalayan salt lamps bad for air quality?

Again, two words: negative ionization.

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

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

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

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

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

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

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

There are two main types of ozone:

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

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

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

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

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

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

So what’s so special about Himalayan salt?

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

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

Salt lamps have been proposed for use in treatments for conditions like chronic obstructive pulmonary disease (COPD) because of their purported therapeutic effects on your respiratory system.

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

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

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

The 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.

$\"Air$

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:

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

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

What should I avoid in an air purifier?

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

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

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

Ionizer air purifiers

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

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

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

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

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

Verdict

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

Ozone Generators

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

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

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

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

Verdict

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

UV Light Purifiers

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

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

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

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

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

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

Verdict

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

In 2020, smoke from wildfires in the western United States drifted for nearly 5,000 miles, eventually being detected in Europe.6 Wildfire safety tips Wildfire smoke events can occur seemingly without warning. 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. Though smoke pollutants carried on the wind may be invisible, their impacts are felt by those most at risk. Smoke pollutants pose health threats that range from irritation and cough to more serious respiratory and cardiac risks. By helping control smoke pollutants that threaten our indoor air quality through monitoring and air purification, it's possible to help manage wildfire smoke health risks.","

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.

Though smoke pollutants carried on the wind may be invisible, their impacts are felt by those most at risk. Smoke pollutants pose health threats that range from irritation and cough to more serious respiratory and cardiac risks.

By helping control smoke pollutants that threaten our indoor air quality through monitoring and air purification, it's possible to help manage wildfire smoke health risks.

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 July 2, 2026, air quality in central Chile remains poor, with major cities experiencing \"unhealthy\" to \"very unhealthy\" levels and high PM2.5 concentrations, posing health risks to residents, especially children and the elderly. By 2:00 AM (Chile Standard Time, GMT-4), some urban centers recorded AQI readings ranging from 100 to 300, 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 2:00 AM (local time) on July 2, 2026. Source: IQAir. Which cities are affected by bad air quality in Chile? As of July 2, 2026, several cities in central Chile are experiencing degraded air quality. Some of the affected cities include: Chillán Coyhaique Rancagua Talca Temuco 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.

Air purifiers may not function properly if placed in an improper space. Discover the ideal air purifier for your space, tailored to meet your needs.

","Air purifiers are powerful air cleaning tools that remove airborne pollutants and harmful chemicals from indoor spaces through multilayer filtration. However, not every air purifier is fit for any sized space. Room dimensions and the environment air purifiers are housed in can greatly impact the performance and filtration efficiency of the device. Understanding optimal air purifier sizes, environments, and locations helps ensure air cleaning systems function properly and are filtrating invisible pollutants with maximum efficiency. What is the best air purifier for my room size? Air cleaning systems are designed to cater to specific types of environments and room sizes to ensure airborne pollutants are properly filtrated and cleaned. Following suggested room air purifier pairing maximizes filtration efficiency and helps secure comprehensively clean air quality. Optimal room size and air purifier type pairings include: Portable air purifiers: Best fitted for small rooms or spaces that are temporarily occupied, such as hotel rooms, personal vehicles, and public bathrooms. Tabletop air purifiers: Best fitted for personal spaces or small rooms with low activity, such as desks, workspaces, or bedrooms. Floor-standing air purifiers: Best fitted for large rooms with high activity or pollutant emissions, such as living rooms, kitchens, and game rooms. HVAC air cleaning systems: Best fitted for whole-house utilization, capturing pollutants through various airducts and vents in a home. Check for suggested dimensions or types of rooms on the air cleaning device’s packaging or instruction manual. Mismatched or unsuitable room and air purifier pairings can lead to compromised air quality conditions, causing elevated health risks and pollutant particle exposure. How does room size impact air purifiers? Improper air purifier and room pairings could greatly reduce performance results, leaving particles untreated and personal health potentially compromised. If a room is too large or has too high of daily activity for an air purifier, the system may take longer to filtrate all pollutant particles effectively, resulting in an unstable air quality conditions and more airborne particulate matter. If a space is too small for a large air purifier, excess electrical utilization and higher utility bills could occur when smaller energy-efficient systems can provide sufficient filtration power. The key to securing maximum protection is understanding environment dynamics and the presence of airborne pollutants, as insufficient air purifier and room pairings can lead to unaddressed air quality concerns. What types of particles do air purifiers filter? If placed in an optimal environment, air purifiers can remove various harmful chemicals and airborne pollutant particles such as PM2.5, PM10, and volatile organic compounds (VOCs) – all linked to respiratory symptoms and elevated health risks. PM2.5 is particulate matter up to 2.5 microns in size and PM10 includes particles up to 10 microns. These particle types include various allergens and indoor pollutants including pollen, pet dander, dust, and smoke. To ensure proper air purifier utilization and maximum filtration efficiency, air metrics and measurements are key in quantifying performance results and ensuring optimal room pairings. How to find the most efficient air purifier for a space Air filtration and ventilation metrics allows for air purifiers to be tested for optimal utilization and ensures air cleaning systems are functioning properly and up to industry standards within the indoor space they are housed in (1). By calculating the Clean Air Delivery Rate (CADR), Air Changes per Hour (ACH), and Cumulative Clean Mass (CCM), an air purifier’s performance efficiency can be quantified and measured. The Clean Air Delivery Rate (CADR) measures how quickly an air cleaning tool can remove pollutants and produce clean air quality. CADR is a metric tool for calculating an air purifier’s initial performance power, but does not determine overall system efficiency and should be used in conjunction with other air metrics. Optimal CADR value should be 2/3 of the total room dimensions, often listed on the outside of product packaging. Air Changes per Hour (ACH) measures how many times air particles are replaced in an indoor space within a 60-minute time period. The Centers for Disease Control and Prevention suggests an ACH value of seven or higher as the “best” ventilation efficiency, labeling an ACH value of four as “good” and a six as “better.” Cumulative Clean Mass (CCM) measures how much pollutants and particulate matter can be captured and filtrated before the air cleaning device loses filtration efficiency. CCM is an optimal metric in determining long-term air purifier performance as it measures efficiency duration. Check the outside product packing and look for higher CCM values such as P4 or F4 – the higher the CCM value, the greater the long-term performance of an air cleaning system. Need help finding the perfect air purifier for your home? CLICK HERE Clean air methods for all indoor spaces Alongside air measurements and metrics, daily clean air methods and practices can help ensure air purifier systems are functioning properly and continue to work at maximum efficiency throughout various rooms (2). By understanding optimal room pairings and clean air practices, comprehensively clean air quality can be achieved with ease, such as: Pollutant source control: Avoid spraying scented or chemical cleaning products, place air purifiers in high activity rooms, and close windows during harmful outdoor air quality events. Room ventilation: Open windows during high indoor activity, install air quality monitors to know when ventilation is safe, and utilize fans to increase airflow and circulation. Efficient filtration: Check air purifier packaging for high CCM or ACH values, place air cleaning devices away from furniture to avoid blockages, and run air systems on a daily schedule to ensure maximum filtration. Analyzing optimal room and air purifier pairings while employing clean air practices provides a pathway to maximum pollutant protection and efficient filtration power. Frequently Asked Questions (FAQs) What air purifier is best for large spaces and low activity? Floor-standing air purifiers are an excellent choice for large spaces with low activity. Large rooms house an abundance of airborne particles that require sufficient filtration to achieve comprehensively clean air quality. If the space has low activity levels, all-day utilization may not be necessary and just a few hours of runtime could be effective enough to filtrate pollutant particles. What air purifier is best for small spaces and high activity? Table-top or floor-standing air purifiers are both effective choices for small spaces with high activity. Compact, personal spaces can be sufficiently cleaned with extended, daily utilization of smaller air purifier units. The key to address heightened levels of pollutant activity is longer runtimes for air cleaning systems – ideally a 24-hour utilization period would provide maximum protection against harmful particles. How long do air purifier filters last? Air purifier filters can last anywhere between 1-4 years, depending on size, model, and daily utilization. How do I know if an air purifier is right for my space?To verify an air purifier is performing at an optimal efficiency within an indoor space, utilize air metrics such as Cumulative Clean Mass (CCM) and Air Changes per Hour (ACH). CCM measures how many pollutant particles can be captured before an air cleaning system loses efficiency, analyzing long-term performance and longevity. Aim to select systems with a CCM value of P4 or F4 – the higher the P and F values, the greater the filtration power of an air purifier. ACH measures how often air particles within an indoor space can be replaced or cleaned in a 60-minute time period. High ACH values have been linked to respiratory and allergen symptom relief, with a ranking of seven or higher labeled as “best” according to the CDC. Conclusion Air purifiers are effective air cleaning tools that remove airborne pollutants, particulate matter, and pollutants from indoor air, but only when paired properly with an optimal room to house the system. Improper room size or environment pairings can impact air purifier performance greatly if placed in an inadequate space type or dimensions. Utilize our room dimension and air purifier pairing guide, and double check efficiency results through performance metrics or air quality monitoring to ensure effective filtration power and comprehensively clean air quality is maintained indoors.","

Clean air methods for all indoor spaces

Alongside air measurements and metrics, daily clean air methods and practices can help ensure air purifier systems are functioning properly and continue to work at maximum efficiency throughout various rooms (2). By understanding optimal room pairings and clean air practices, comprehensively clean air quality can be achieved with ease, such as:

\nPollutant source control: Avoid spraying scented or chemical cleaning products, place air purifiers in high activity rooms, and close windows during harmful outdoor air quality events.
\nRoom ventilation: Open windows during high indoor activity, install air quality monitors to know when ventilation is safe, and utilize fans to increase airflow and circulation.
\nEfficient filtration: Check air purifier packaging for high CCM or ACH values, place air cleaning devices away from furniture to avoid blockages, and run air systems on a daily schedule to ensure maximum filtration.

Analyzing optimal room and air purifier pairings while employing clean air practices provides a pathway to maximum pollutant protection and efficient filtration power.

Frequently Asked Questions (FAQs)

What air purifier is best for large spaces and low activity?
Floor-standing air purifiers are an excellent choice for large spaces with low activity.

Large rooms house an abundance of airborne particles that require sufficient filtration to achieve comprehensively clean air quality. If the space has low activity levels, all-day utilization may not be necessary and just a few hours of runtime could be effective enough to filtrate pollutant particles.

What air purifier is best for small spaces and high activity?
Table-top or floor-standing air purifiers are both effective choices for small spaces with high activity.

Compact, personal spaces can be sufficiently cleaned with extended, daily utilization of smaller air purifier units. The key to address heightened levels of pollutant activity is longer runtimes for air cleaning systems – ideally a 24-hour utilization period would provide maximum protection against harmful particles.

How long do air purifier filters last?
Air purifier filters can last anywhere between 1-4 years, depending on size, model, and daily utilization.

How do I know if an air purifier is right for my space?
To verify an air purifier is performing at an optimal efficiency within an indoor space, utilize air metrics such as Cumulative Clean Mass (CCM) and Air Changes per Hour (ACH).

CCM measures how many pollutant particles can be captured before an air cleaning system loses efficiency, analyzing long-term performance and longevity. Aim to select systems with a CCM value of P4 or F4 – the higher the P and F values, the greater the filtration power of an air purifier.

ACH measures how often air particles within an indoor space can be replaced or cleaned in a 60-minute time period. High ACH values have been linked to respiratory and allergen symptom relief, with a ranking of seven or higher labeled as “best” according to the CDC.

Conclusion

Air purifiers are effective air cleaning tools that remove airborne pollutants, particulate matter, and pollutants from indoor air, but only when paired properly with an optimal room to house the system. Improper room size or environment pairings can impact air purifier performance greatly if placed in an inadequate space type or dimensions.

Utilize our room dimension and air purifier pairing guide, and double check efficiency results through performance metrics or air quality monitoring to ensure effective filtration power and comprehensively clean air quality is maintained indoors.

What fireworks do to air quality

From sparklers, smoke bombs and firecrackers, to spectacular overhead explosions, all fireworks release combustion particles and gases into the air. These can ultimately travel for miles on wind currents.

Two common sources of pollutants in fireworks are:

Black powder (gunpowder) – a mixture of sulfur, charcoal, and potassium nitrate
Colorants – chemicals that radiate different colors when ignited

The chemicals in the colorants are wide-ranging and often toxic. They include:

Strontium, lithium (for reds)
Calcium, calcium chloride (oranges)
Sodium, sodium chloride (yellows)
Barium (greens)
Copper (blues)
Chlorine (greens and blues)

Typical types of particles that fireworks introduce into the atmosphere are PM2.5, PM10 (coarse particles ranging from 2.5–10 microns in diameter), PM0.1 (ultrafine particles—also known as UFPs—smaller than 0.3 microns in diameter, and by far the most dangerous), and volatile organic compounds (also known as VOCs, airborne vapor or gaseous compounds responsible for many odors). Note that many of these particles are so tiny that they can be inhaled into the lungs where they infiltrate the bloodstream, causing many health problems.

Learn more.","Give a truly meaningful gift that can provide long-lasting health benefits to loved ones. And what could be more beneficial than the gift of clean air? We have your ultimate holiday gift guide. You are sure to find some gift ideas that fit the bill. What gifts are trending in 2024? Wondering what the hot gifts are this year? Air quality gifts are increasingly popular in 2024, with air purifiers leading the trend. They’re highly sought after to capture airborne pollutants, allergens, and bacteria. HyperHEPA filtration systems help improve overall well-being, especially as studies have shown that 92% of people are exposed to unsafe levels of particulate matter (1). Is an air purifier a good gift? Given the fact that most of us are exposed to high levels of poor air quality every day, air purification is an essential component of modern, healthful living. Gifting your family and friends an air purifier shows how much you care. The quality of the air you breathe is linked to your immune system, mood, cognitive function, and even your lifespan. You take approximately 25,000 breaths a day – why not make every single breath as healthy as possible (2)? The quality of the air you breathe is linked to your immune system, mood, cognitive function, and even your lifespan. Air purifiers are one of the best gifts to give to not just friends and family members suffering from allergies, asthma, or any other respiratory-related affliction, but also anyone concerned about the air quality in their home, vehicle, or workplace. And since the World Health Organization (WHO) confirmed that 92% of the world’s population lives in places where air quality levels exceed WHO limits, virtually everyone should consider using an air purifier to protect themselves against indoor air pollution (3). Create a clean air haven For any building or indoor setting, IQAir’s advanced air filtration systems provide the ultimate solution – a gift that creates a clean air haven in the home. For any building or indoor setting, IQAir’s advanced air filtration systems provide the ultimate solution – a gift that creates a clean air haven in the home A high-efficiency home purifier or powerful, energy efficient air purifier will clean the air in home offices and larger spaces while people are working, studying, or in living and dining rooms while they gather. With sound-attenuating filters and double-walled housing, a home air purifier can even be quiet enough to clean the air at night while the family sleeps. For the kitchen, an optional gas and odour filter can capture cooking and cleaning odours. Another solution for direct, focused clean air is gifting a desk air purifier. Portable and able to be setup on any flat surface, desk air purifiers can deliver clean air to breathing spaces in nurseries, on bed stands, at desks, or from end tables. Road traffic is a major contributing source of nitrogen dioxides and volatile organic compounds (VOCs). When the two pollutants combine, they can create ozone. Vehicle combustion also produces particle matter. If your loved one is always on the road, a portable car air purifier can help keep the air safe within their vehicle interior. Here’s why IQAir offers the best air purifiers and is your go-to solution for air-cleaning needs: HyperHEPA filtration technology is tested and certified by an independent third-party lab to effectively filter harmful ultrafine pollution particles down to 0.003 microns in size. For perspective, this is 100 times smaller than what is accomplished with conventional air filtration technology and 10 times smaller than a virus. Each system is individually tested at the factory and is certified to filter a minimum of 99.5% of all particles 0.003 microns or larger. Unlike other air purifiers, IQAir systems are designed to ensure that all the air goes completely through the filters and not around it like other leaky designs. If it doesn’t meet or exceed these performance standards, it doesn’t leave our factory — period. Unparalleled performance achieved through safe, healthy technology. IQAir air filtration solutions use only safe, proven, mechanical filtration technology, without generating dangerous ions, ozone, or UV. Swiss Made quality is at the very core of everything that IQAir does.

To sum it up: IQAir air-filtration systems are certified and proven to filter more, last longer, and work harder than other air purifiers on the market. They are the ultimate clean air gifts. Air quality monitors How can the people you care about most tell when airborne pollutants are in their environment? With an air quality monitor. Consider the world's smartest air quality monitors from IQAir’s AirVisual Series that precisely measures and records air quality indoors and outdoors, wherever you go. Advanced smart technology allows you to set up personalized air quality alerts as well as link AirVisual Series air quality monitors with your connected home technology to maximise clean air while minimising home HVAC costs. Great free gift idea: Air quality app A great free gift option is the AirVisual app, which provides real-time air quality data and forecast alerts worldwide. It’s a perfect gift for anyone looking to monitor air quality and take proactive steps to protect their health. The app delivers personalized air quality alerts and integrates with smart home systems, making it a useful tool for reducing pollution exposure. Gifting the AirVisual app offers friends and family an easy way to stay informed about air conditions and make healthier lifestyle choices. Personal protection for better air quality For those loved ones who spend extended periods of time outdoors when the air quality is poor, a gift of personal protection masks will be appreciated. The IQAir Mask promises to protect against the most dangerous airborne particulate matter. Multi-layer HyperHEPA media filtration is effective against 95% of particles, including those insidious, harmful ultrafine particles. An ergonomic, user-friendly design ensures that this all-day pollution protection is as comfortable as it is easy-to-use. The IQAir Mask is excellent for use by construction, utility, and sanitation workers, landscapers, emergency personnel, and all others whose jobs demand they continue to work outdoors even during times of hazardous air quality. Make sure gifts don’t decrease air quality It’s important to consider gifts that don't compromise air quality. For instance, avoid items that off-gas VOCs, such as certain plastics. Instead, choose toys and products made from natural materials like solid wood, and ensure any used paints, stains, or adhesives are low in VOCs (4). More natural gift choices not only provide safer alternatives but also contribute to maintaining a clean air environment. If at the top of your holiday gift guide for dad is a barbecue grill, choose one that uses propane or natural gas instead of charcoal. The gas models do release some pollutants, including carbon dioxide, into the air. But burning charcoal emits much more particulate matter and about twice the carbon dioxide. Using lighting fluid to help ignite charcoal adds polycyclic aromatic hydrocarbons (PAHs) to those emissions (5). A holiday gift guide for mom could include a vacuum cleaner. If so, make sure you get her one that includes a true HEPA filter that can trap the dust, pet dander, pollen and other surface particles and don’t recirculate them back into the air like standard vacuums can. Scented candles are a lovely gift. Unfortunately, even when not lit, they can emit VOCs into the air. Better are essential oils (not fragrance oils that contain artificial ingredients) and containers of potpourri.

Give a truly meaningful gift that can provide long-lasting health benefits to loved ones. And what could be more beneficial than the gift of clean air?

We have your ultimate holiday gift guide. You are sure to find some gift ideas that fit the bill.

What gifts are trending in 2024?

Wondering what the hot gifts are this year? Air quality gifts are increasingly popular in 2024, with air purifiers leading the trend. They’re highly sought after to capture airborne pollutants, allergens, and bacteria.

HyperHEPA filtration systems help improve overall well-being, especially as studies have shown that 92% of people are exposed to unsafe levels of particulate matter (1).

Is an air purifier a good gift?

Given the fact that most of us are exposed to high levels of poor air quality every day, air purification is an essential component of modern, healthful living. Gifting your family and friends an air purifier shows how much you care.

The quality of the air you breathe is linked to your immune system, mood, cognitive function, and even your lifespan. You take approximately 25,000 breaths a day – why not make every single breath as healthy as possible (2)?

The quality of the air you breathe is linked to your immune system, mood, cognitive function, and even your lifespan.

Air purifiers are one of the best gifts to give to not just friends and family members suffering from allergies, asthma, or any other respiratory-related affliction, but also anyone concerned about the air quality in their home, vehicle, or workplace.

And since the World Health Organization (WHO) confirmed that 92% of the world’s population lives in places where air quality levels exceed WHO limits, virtually everyone should consider using an air purifier to protect themselves against indoor air pollution (3).

Create a clean air haven

For any building or indoor setting, IQAir’s advanced air filtration systems provide the ultimate solution – a gift that creates a clean air haven in the home.

For any building or indoor setting, IQAir’s advanced air filtration systems provide the ultimate solution – a gift that creates a clean air haven in the home

A high-efficiency home purifier or powerful, energy efficient air purifier will clean the air in home offices and larger spaces while people are working, studying, or in living and dining rooms while they gather. With sound-attenuating filters and double-walled housing, a home air purifier can even be quiet enough to clean the air at night while the family sleeps. For the kitchen, an optional gas and odour filter can capture cooking and cleaning odours.

Another solution for direct, focused clean air is gifting a desk air purifier. Portable and able to be setup on any flat surface, desk air purifiers can deliver clean air to breathing spaces in nurseries, on bed stands, at desks, or from end tables.

Road traffic is a major contributing source of nitrogen dioxides and volatile organic compounds (VOCs). When the two pollutants combine, they can create ozone. Vehicle combustion also produces particle matter. If your loved one is always on the road, a portable car air purifier can help keep the air safe within their vehicle interior.

Here’s why IQAir offers the best air purifiers and is your go-to solution for air-cleaning needs:

HyperHEPA filtration technology is tested and certified by an independent third-party lab to effectively filter harmful ultrafine pollution particles down to 0.003 microns in size. For perspective, this is 100 times smaller than what is accomplished with conventional air filtration technology and 10 times smaller than a virus.
Each system is individually tested at the factory and is certified to filter a minimum of 99.5% of all particles 0.003 microns or larger. Unlike other air purifiers, IQAir systems are designed to ensure that all the air goes completely through the filters and not around it like other leaky designs. If it doesn’t meet or exceed these performance standards, it doesn’t leave our factory — period.
Unparalleled performance achieved through safe, healthy technology. IQAir air filtration solutions use only safe, proven, mechanical filtration technology, without generating dangerous ions, ozone, or UV.
Swiss Made quality is at the very core of everything that IQAir does. By using the finest quality components, a specialized team of highly skilled technicians, and cutting-edge manufacturing processes refined for more than 60 years, IQAir builds the best air purifiers in the world.

To sum it up: IQAir air-filtration systems are certified and proven to filter more, last longer, and work harder than other air purifiers on the market. They are the ultimate clean air gifts.

Air quality monitors

How can the people you care about most tell when airborne pollutants are in their environment? With an air quality monitor.

Consider the world's smartest air quality monitors from IQAir’s AirVisual Series that precisely measures and records air quality indoors and outdoors, wherever you go.

Advanced smart technology allows you to set up personalized air quality alerts as well as link AirVisual Series air quality monitors with your connected home technology to maximise clean air while minimising home HVAC costs.

Great free gift idea: Air quality app

A great free gift option is the AirVisual app, which provides real-time air quality data and forecast alerts worldwide. It’s a perfect gift for anyone looking to monitor air quality and take proactive steps to protect their health.

The app delivers personalized air quality alerts and integrates with smart home systems, making it a useful tool for reducing pollution exposure. Gifting the AirVisual app offers friends and family an easy way to stay informed about air conditions and make healthier lifestyle choices.

Personal protection for better air quality

For those loved ones who spend extended periods of time outdoors when the air quality is poor, a gift of personal protection masks will be appreciated. The IQAir Mask promises to protect against the most dangerous airborne particulate matter.

Multi-layer HyperHEPA media filtration is effective against 95% of particles, including those insidious, harmful ultrafine particles. An ergonomic, user-friendly design ensures that this all-day pollution protection is as comfortable as it is easy-to-use.

The IQAir Mask is excellent for use by construction, utility, and sanitation workers, landscapers, emergency personnel, and all others whose jobs demand they continue to work outdoors even during times of hazardous air quality.

Make sure gifts don’t decrease air quality

It’s important to consider gifts that don't compromise air quality. For instance, avoid items that off-gas VOCs, such as certain plastics. Instead, choose toys and products made from natural materials like solid wood, and ensure any used paints, stains, or adhesives are low in VOCs (4). More natural gift choices not only provide safer alternatives but also contribute to maintaining a clean air environment.

If at the top of your holiday gift guide for dad is a barbecue grill, choose one that uses propane or natural gas instead of charcoal. The gas models do release some pollutants, including carbon dioxide, into the air. But burning charcoal emits much more particulate matter and about twice the carbon dioxide. Using lighting fluid to help ignite charcoal adds polycyclic aromatic hydrocarbons (PAHs) to those emissions (5).

A holiday gift guide for mom could include a vacuum cleaner. If so, make sure you get her one that includes a true HEPA filter that can trap the dust, pet dander, pollen and other surface particles and don’t recirculate them back into the air like standard vacuums can.

Scented candles are a lovely gift. Unfortunately, even when not lit, they can emit VOCs into the air. Better are essential oils (not fragrance oils that contain artificial ingredients) and containers of potpourri. Or you can put together your own little bags filled with cinnamon sticks, cloves, and other spices that gift recipients can simmer in water.

In general, before buying a gift, consider how it will affect the air quality. If it will harm the air quality, we suggest looking for similar alternatives or avoiding them altogether.

Give the gift of clean air to communities in need

If you prefer to give back this holiday season, consider donating to clean air initiatives instead of traditional gifts. Contributions to the IQAir Foundation can help provide clean air solutions to underserved communities around the world and protect vulnerable populations from harmful air pollutants.

Or instead of a present, you can ask your loved ones to make a donation on your behalf and support life-changing programs that monitor air quality, install air purifiers, and promote healthier living environments globally. Every donation helps create cleaner, healthier air for those who need it most.

Conclusion

If your holiday gift guide includes air purifiers and air quality monitoring technology this year, be sure to choose quality. An air purifier that’s properly maintained is an investment that can be appreciated and provide protection against airborne pollutants for many years after celebrations end.

Learn more.","Christmas trees help set the holiday mood with twinkling lights, shiny ornaments, and the scent of pine. Christmas tree production is a global business; in 2021 there were 1,364 Christmas tree farms in Canada and 3,350 such farms in Germany (1)(2). In America, people buy approximately 25-30 million live Christmas trees each year to decorate their homes for the holidays (3). About 85% of those trees will be pre-cut weeks ahead of time – in most cases prior to when Americans celebrate Thanksgiving. The trees are cut, baled, and packed into refrigerated trucks to be delivered to a tree seller near your home. Moisture and the tight bundling of the trees supports an ideal environment for mold to grow. Unfortunately, along the way, moisture and the tight bundling of the trees supports an ideal environment for mold to grow. In many cases, once the tree gets into your home the mold on the tree begins reproducing, triggering an allergic reaction known as “Christmas tree syndrome.” According to the National Asthma Council of Australia, about 6% of the general population with allergies suffers from Christmas tree allergy symptoms that include (4): sneezing coughing congestion runny nose itchy nose and throat itchy or watery eyes dry, scaly skin Do you have a Christmas tree allergy? If you find yourself sneezing, coughing, or experiencing itchy eyes and throat soon after setting up your tree, then yes – you might have a Christmas tree allergy. This condition is often triggered by mold spores or pollen that the tree carries into your home. While pine pollen itself may not be a major concern during winter, other allergens such as ragweed or grass pollen, and even mold, can hitch a ride on your tree, leading to uncomfortable symptoms. Christmas trees and mold In one study, researchers closely measured mold counts in a room that contained a live Christmas tree. During the first three days that the tree was indoors, the count of mold spores in the air remained at about 800 spores per cubic meter of air. Starting on the fourth day, however, the spore counts began rising and eventually reached 5,000 mold spores in the air per cubic meter within two weeks (5). Counts higher than 700 spores per cubic meter are an indication that mold growth is occurring in an environment. Researchers examining 23 samples of bark and pine needles from Christmas trees found 53 different kinds of mold. In another study, researchers examining 23 samples of bark and pine needles from Christmas trees found 53 different kinds of mold. Many of the mold varieties found on the trees were those most likely to trigger allergies – including (6): Aspergillus. This type of mold is especially dangerous for individuals with compromised immune systems. Penicillium. The mold from which penicillin is made, it causes allergic reactions in some people. Cladosporium. A common mold that can cause skin infections and allergic symptoms. The World Health Organization considers indoor concentrations greater than 500 spores per cubic meter to be unacceptable. Although there is no single set of state or federal standards regarding acceptable indoor mold spore levels, the World Health Organization considers indoor concentrations greater than 500 spores per cubic meter to be unacceptable. At the very least, the elevated mold spore levels associated with live Christmas trees means that families with allergies should consider keeping a live tree indoors no more than a few days, especially if there are signs of increased allergies, which might be from Christmas tree syndrome. Pollen can also be a problem Pine pollen is not a major issue with Christmas tree allergy symptoms, because evergreen plants pollinate in the spring, not in early winter. However, the trees come into contact with allergens such as ragweed pollen and may carry it into the house where it can distress those with ragweed allergies. Ragweed is an invasive species of the Asteraceae family and Ambrosia genus of plants (7). Ragweed is not a single plant but a collection of between 17 and 20 different species in North America that typically have tall, skinny stems with green flower spikes that do not contain nectar and are not attractive to pollinators. Ragweed plants are prodigious producers of pollen – one plant can release up to one billion grains into the atmosphere – which can then travel hundreds of miles. Instead, ragweed pollen distribution is facilitated by the wind. And ragweed plants are prodigious producers of pollen – one plant can release up to one billion grains into the atmosphere – which can then travel hundreds of miles, though most of the pollen remains close to the plants that produced it (8). These plants are more prevalent in the Eastern and Midwestern U.S., particularly in rural areas. There, common sites for ragweed invasions are in fields and along roadsides and riverbanks. In urban areas, the plants often flourish in vacant lots since turfgrass and other cultivated species help prevent ragweed from taking hold. Seeds from ragweed species can remain dormant in the ground for decades before finally germinating. And ragweed is not the only member from this family of plants that can latch on to Christmas trees. Other members include: sage rabbit brush groundsel bush burweed marsh elder mugwort eupatorium Another allergen that a Christmas tree can be the source of in your house is grass pollen, which can stick to the tree’s sap during the spring. Then, when the tree is harvested and brought indoors, the sap dries out and the trapped pollen particles are released into the air. How do you prevent Christmas tree allergy? If you still cherish the idea of a live Christmas tree in your home for the holidays, take heart. You don’t have to suffer a Christmas tree rash. Here are a few simple steps you can take to reduce the likelihood that you or someone in your home will suffer from Christmas tree syndrome: Clean and wipe the trunk of your tree thoroughly with water and bleach before you bring it into the house. Use a leaf blower to remove as many pollen grains as possible before bringing the tree indoors. Get rid of the tree sooner. Mold spores increase the longer the tree is around. Consider removing the tree from your home the day after Christmas. Consider purchasing a self-cut tree.

Most of these deaths – 89% - take place in low- to middle-income countries, largely in WHO-designated South-East Asia and the Western Pacific regions. Those regions countries that have been among the thirty most polluted countries in the world., including Bangladesh, India, Indonesia, Laos, Mongolia, Myanmar, Nepal, Pakistan, and Vietnam. According to the WHO, half of the deaths caused by air pollution in 2020 were linked to indoor sources such as cooking over coal, wood or biomass stoves (3). The majority of people impacted were women and children, including more than 237,000 children under age 5. Air pollution is now the world’s greatest single environmental risk. Air pollution is now the world’s greatest single environmental risk (4) . The most common and dangerous pollutant is PM2.5, particulate matter measuring under 2.5 microns in diameter. PM2.5 is linked to both heart and lung disease. Examples from history The “Great Smog of London” is an example of the impact of air pollution on premature death rates. During a single weekend in 1952, pollution from coal-burning fireplaces was trapped over the city during a cold-weather inversion. The pollution exposure during that one single weekend caused more than 12,000 premature deaths and according to a study published in the American Journal of Respiratory and Critical Care Medicine, there was a significant increase in adult and childhood asthma cases following the event (5)(6). In ancient times, air quality was also a cause of premature death. Researchers from the University of Manchester (U.K.) studied 15 lungs from ancient Egyptian mummies. They found high levels of particulates and lung scarring in all of them (7). The source of the particulates is believed to have been sandstorms and burning fossil fuels. Air pollution and premature death today More than 3,500 years later, air pollution is still a growing cause of premature death in many parts of the world. . Today, outdoor PM2.5 sources include vehicle emissions, power plant emissions, industrial processes, agricultural burning, and wildfire smoke. Indoor PM2.5 sources may include fuel-burning appliances and home heating. For far too many people, regularly breathing polluted air poses a significant health risk. A study published in Lancet Planetary Health found that in India, deaths increased by 1.5 million people per year due to long-term exposure to air pollution (8). In South Asia, pollution levels routinely exceed “hazardous” air quality levels in Bangladesh, Pakistan, and India across multiple years. Why is air pollution so dangerous? There are at least four specific ways air pollution contributes to premature death rates: Heart Disease. A study published at the University of California, Berkeley, linked air pollution exposure to premature death from ischemic heart disease, which is reduced blood supply to the heart (9). Heart disease is the #1 cause of death in the U.S. (10) Cancer. Lung cancer was the leading cause of cancer in 2022, accounting for 1.8 million deaths (11). The International Agency for Research on Cancer has classified particulate pollution as carcinogenic (12). Asthma. Air pollution is a major cause of asthma attacks. Asthma affected around 262 million people around the globe in 2019 and led to an estimated 455,000 deaths (13). COPD. Air pollution is a leading cause of chronic obstructive pulmonary disease (COPD). The two most common forms of the disease are emphysema and bronchitis. An estimated 43% of global COPD deaths have been attributed to air pollution (14). Take action against air pollution The most important strategy for controlling air pollution and improving air quality is to reduce the sources of air pollution – especially pollution from traffic and power generation. Here are a few suggested steps you can take, to control air pollution at the source, measure air quality and know when it’s poor, and maintain a healthy lifestyle on those poor air quality days: On the road: Walk or ride a bike whenever possible. Take public transportation and advocate for increased access to clean energy public transportation in your community. When purchasing a new car, choose a low-polluting or zero-emission vehicle. Wear a FFP2 mask when outdoor air quality is poor. Keep your vehicle’s cabin healthy with a compact vehicle air purifier. At home: Turn off the lights when you leave a room. Replace incandescent lights with compact fluorescent light bulbs and look for energy-efficient appliances when replacing older appliances. Use clean cookstoves and reduce dependence on both gas burning stoves and gas-powered appliances (15).Avoid burning candles and incense by choosing cleaner air freshening options. Use a programmable thermostat and set it to 78 degrees in summer and 68 degrees in winter. Download a free air quality app to know the air quality in your neighborhood. Monitor your air quality both indoor and outdoors. Improve ventilation by opening windows when indoor air quality is poor and by closing them when outdoor air quality conditions degrade. Set to HVAC to recirculate mode when outdoor air quality is poor.Run a high-performance air purifier to maintain clean indoor air. At work: Join a carpool. Telecommute. Open the blinds and turn off the lights whenever possible. Become a Clean Air Facility to comprehensively improve your workplace’s air quality. Conclusion Air pollution kills nearly 7 million people yearly, mostly in poorer nations, due to heart disease, cancer, and lung illnesses. Indoor pollution from cooking with dirty fuels and outdoor smog cut lives short by years. Yet controlling source pollutants, improving indoor ventilation, and filtration can all provide clean air solutions. From London’s 1952 smog to today’s global crisis, the pattern is clear: strong action saves lives. Switching to clean transport, cookstoves, and renewable energy can slash deaths and add years to life expectancy—but only if we act now.","

Conclusion

Air pollution kills nearly 7 million people yearly, mostly in poorer nations, due to heart disease, cancer, and lung illnesses. Indoor pollution from cooking with dirty fuels and outdoor smog cut lives short by years. Yet controlling source pollutants, improving indoor ventilation, and filtration can all provide clean air solutions.

From London’s 1952 smog to today’s global crisis, the pattern is clear: strong action saves lives. Switching to clean transport, cookstoves, and renewable energy can slash deaths and add years to life expectancy—but only if we act now.

PM2.5 particles measure 2.5 microns or less in diameter. PM2.5 particles are so small they can only be seen with an electron microscope. Of all air pollution measures, PM2.5 pollution poses the greatest health threat (1). Due to its small size, PM2.5 can remain suspended in the air for days or weeks, traveling across cities, regions, and even continents and can be absorbed deep into the bloodstream upon inhalation. Globally and in IQAir’s AQI⁺, PM2.5 and ozone stand out as the most common primary air pollutants. That’s why monitoring these two pollutants is particularly critical for human health. Why is PM2.5 often the primary pollutant? PM2.5 is the most common primary pollutant in air quality reports because it is exceptionally small, persistent, and widespread. It originates from nearly all major pollution sources—vehicles, industrial emissions, wildfires, agricultural burning, and household activities—making it a universal marker of poor air quality. Its microscopic size allows PM2.5 to penetrate buildings and reach deep into the lungs and bloodstream, posing both immediate and long-term health risks. As a result, it frequently appears as the “main pollutant” in AQI reports, since it is more likely than others to exceed safety thresholds and impact large populations. Because PM2.5 is so central to how air quality is reported and understood, it’s helpful to understand the air quality indexes that communicate these pollution levels. What is AQI? An air quality index, or AQI, is used to help quickly communicate air quality levels, with categories ranging from “Good” to “Hazardous.” Traditional U.S. AQI calculations rely on 24-hour averages for pollutants like PM2.5. IQAir’s AQI⁺ provides users with hourly air quality updates. Because PM2.5 levels can change rapidly throughout the day, hourly updates offer a more accurate, real-time picture of exposure. What are the sources of PM2.5 pollution? Particulate matter can be either emitted directly from manmade or natural sources, with manmade sources generally resulting in greater amount of PM2.5 (2). Some of the most common manmade sources of pollutant PM2.5 are (3) (4) (5): Motor combustion Power plant combustion Industrial processes Stoves, fireplaces, and home wood burning Smoke from fireworks Smoking Natural sources of PM2.5 can include: Dust Soot Dirt Windblown salt Plant spores Pollen Smoke from wildfires The dominant sources of PM2.5 air quality can vary depending on the season, weather, climate, level of urbanization, country, and region. A 1994 study in Atmospheric Environment looked at PM2.5 sources in the United States, determining that biomass burnings were the highest contributors to PM2.5 pollution in the Northwest, while residual oil combustion was the dominant source in the Northeast and in major seaport cities (6). Sources of pollutants can include emissions from neighboring countries. A 2019 study of source contributions in Canada published in Environmental Science and Technology found that 33 percent of Central Canada’s pollutant PM2.5 originated in the U.S. (7). The same study uncovered that residential combustion was the primary source of PM2.5 in Central Canada, while wildfires were the responsible sources for PM2.5 pollution in Northern, Atlantic, and Western Canada. What are the chemical components of PM2.5? PM2.5 can be created by other pollutants chemically reacting in the atmosphere. Chemical reaction between gases can be sources of PM2.5 pollutants, including reactions between (8): Sulfur dioxide Nitrogen oxides Ammonia Black carbon Mineral dust Water Volatile organic compounds How does PM2.5 pollution affect our health? PM 2.5’s microscopic size increases its potential to be lodged deep into the respiratory tracts. At 2.5 microns, PM2.5 can enter the circulatory system and even the brain (9). Short term symptoms of exposure to high levels of particulate matter include irritation of the throat and airways, coughing, and difficulty breathing (10). More serious, long-term complications can include: Heart and lung disease Bronchitis Emphysema Nonfatal heart attacks Irregular heartbeat Asthma and more intense flareups Decreased lung function Early death People with heart or lung diseases, children, and older adults are most likely to be affected by particle pollution exposure. Numerous studies have confirmed a multitude of serious health complications caused by exposure to pollutant PM2.5. For example, a 2011 study published in The American Journal of Respiratory and Critical Care Medicine tracked 1.2 million Americans from 1982 until 2008 (11). Each 10 microgram per cubic meter increase in PM2.5 concentrations was associated with a 15-27% increase in lung cancer mortality. PM2.5 pollution has been tied to increased risk of asthma in young children in Denmark, according to a 2020 study published in the British Medical Journal(12). All children born between 1997 and 2014 were followed for asthma onset and persistent wheezing from age 1 to 15. The study found that children exposed to higher levels of PM2.5 were more likely to develop asthma and persistent wheezing than children who weren’t exposed. Is there a difference between PM2.5 and PM10? PM10 and PM2.5 are both forms of pollutants that are different sizes. PM2.5 particles are fine and PM10 is larger and coarser. PM10 particles are between 2.5 and 10 micrograms. Our bodies can more easily defend against PM10 by sneezing or coughing. Those defenses don’t work with smaller particles (13). PM10 can embed within the lungs where they are associated with adverse health impacts, such as lung tissue damage and asthma. However, PM10 isn’t as likely to enter the blood stream as PM2.5 due to its size (14). What are the environmental effects of PM2.5 air quality? PM2.5 causes environmental harm in several ways, such as (15): Damage of materials and buildings Acid deposition Increased ozone levels PM2.5 pollution can travel long distances through strong winds, up to hundreds of thousands of miles from their source (16). PM2.5 can be carried to coastal waters and river basins, where they change the nutrient balance. When particle pollution settles on crops and forests, it can damage the vegetation. What can be done about PM2.5 pollution? People with concerns about PM2.5 in their environment can advocate for clean air legislation and for low-emission zones. Reducing PM2.5 and PM10 air pollution is a priority for most countries. India joined the United Nation’s Climate and Clean Air Coalition in 2019 with the goal of reducing national particulate pollution by 20 to 30 percent by 2024.

The pollution doesn’t disappear when cooler temps arrive on the Arabian Peninsula. Learn why dust remains a problem and how to stay safe from unhealthy air year-round.

","Global hubs like Doha, Qatar, Dubai, UAE, Kuwait City, Kuwait, Manama, and Bahrain, lie on the coastal area of the Arabian Peninsula and are home to millions of residents and expatriates. These cities regularly rank among the most polluted major cities in the world due to persistently high dust concentrations, even in winter. This makes air quality a year-round public health priority. While dust storms are usually associated with scorching summer temperatures, winter brings its own air quality health concerns. Winter dust and sand can pose an equally serious threat to human health on the Arabian Peninsula for some surprising reasons. Contrary to what many expect, cooler winter weather doesn’t bring cleaner air or less air pollution to the Arabian Peninsula. The winter dust paradox A combination of meteorological and human factors ensures the persistence of dust through the Arabian Peninsula’s winter months. Strong seasonal winds, like the northwesterly “shamal,” carry fine particles from the deserts of Iraq, Saudi Arabia, and Iran into Arabian Peninsula communities (1). Although dry, hot shamals are typically associated with the summer, they can occur in winter as well. And while dust storms are less common than in summer, they can still trigger flight cancellations and school closures (2).

In addition to these wind-driven events, other natural and human sources add to the region’s burden. Salt blown in from the sea, rapid-paced construction, and vehicle and petrochemical industrial emissions all contribute to wintertime pollution (3). As a result, the largest cities on the Arabian Peninsula routinely exceed the WHO guideline for PM2.5 of 5 μg/m3 or less, even in winter. According to the 2024 World Air Quality Report, Bahrain, Iraq, Kuwait, Qatar, and the United Arab Emirates were among the top 25 most polluted cities in 2024, in part due to the consistently poor air quality throughout the year. Another regional nation, Iran, was absent from the report due to a lack of air quality monitoring data.Unlike in the summer, winter dust can be more insidious.

Millions burn biomass for heating, cooking, and crop waste removal. Find out why the cost in health and lives is too high to continue.

","Every day, nearly 3 billion people light fires to cook, heat their homes, or clear land. These fires fill the air with a toxic cocktail of pollutants. Black plumes of smoke rise from woodstoves, crop fields, and wildfires to form a long-term public health crisis. These practices are collectively known as biomass burning—the combustion of organic materials like wood, crop waste, and dung. Biomass burning pumps out PM2.5 (particulate matter measuring 2.5 microns in diameter or smaller), carbon monoxide, and other pollutants linked to millions of premature deaths each year from stroke, heart disease, and respiratory illnesses. Biomass is sometimes deemed “renewable,” but its smoke is anything but harmless. Although biomass burning occurs worldwide, its impacts extend far beyond the communities where the smoke is produced; black carbon from incomplete combustion accelerates glacier melt, disrupts rainfall, and crosses oceans. What is biomass burning? People have used biomass for energy since the earliest humans first lit wood fires for cooking and warmth. Biomass is organic material from living—or recently living—organisms, such as wood, crop residues, and animal waste. Examples of organic materials may include: Charcoal Crop waste Dung Wood Today, biomass is widely burned for cooking and heating, and, in some places, it is also used to generate electricity and power industrial systems (1). While some biomass burning results from natural processes like lightning-sparked wildfires, it is generally derived from human activity. Because biomass burning is so widespread and often happens close to where people live, its health impacts are felt most by those exposed to the smoke every day. Who breathes biomass smoke? Because biomass burning often occurs indoors or near homes, exposure falls hardest on those who spend the most time nearby. In rural homes across sub-Saharan Africa, Central and South Asia, and Latin America, women and girls spend hours each day gathered around open fires or rudimentary stoves. The consequences are devastating; the World Health Organization estimates that household air pollution from biomass kills over 3 million people annually (2). The World Health Organization estimates that household air pollution from biomass kills over 3 million people annually. Those most affected by biomass burning are also often the most vulnerable: elders, women, and children. Children under five are particularly at risk for pneumonia—the leading infectious killer of children worldwide. Even before they take their first breath, babies born to mothers exposed to biomass smoke face higher risks of low birth weight (3). For families already stretched thin by poverty, the cycle is brutal; time spent collecting firewood is time lost to education or work, and medical bills for smoke-related illnesses push millions deeper into debt. Though the impacts are most acute in less affluent regions, biomass smoke affects everyone, regardless of geography or income. In wealthier nations, wildfires are growing more intense and long-lasting due to climate change. Wildfire smoke can drift for miles and blanket cities for weeks at a time. Wood pellet burning, fireplaces, and backyard fire pits can all contribute to poor air quality as well. Where biomass is produced for energy Biomass is used very differently around the world. In some countries, it is produced at industrial scale and treated as an energy commodity—often to generate electricity, produce liquid biofuels, or supply heating fuel. Industrial biomass fuel production is greatest in the United States, which converts corn to ethanol for gasoline and electrical production. In 2024, the U.S. produced equal to about 856,000 barrels of oil (BOE) in biomass per day (4). Brazil is the second largest producer at 510,000 BOEs per day, primarily sourced from sugarcane. Indonesia produces 205,000 BOEs each day mostly from palm oil, but also from crop waste, wood, and coconut shells. China, India, and Germany follow as the next largest biofuel producers. Where biomass is burned for daily survival In contrast to industrial bioenergy production, many countries rely on biomass burning not by choice, but out of necessity. In these countries there is an overwhelming dependence on biomass burning for household cooking and heating.

Pollution doesn’t stay outside. Discover what in the air in homes near freeways—and how to reduce risk.

","Living near a freeway brings convenience — but also invisible risks. Studies show that homes, schools, and apartments within a few hundred meters of major roadways are exposed to elevated traffic pollution (1,2). And those pollutants don’t stay outside: many seep into indoor spaces, quietly affecting health, comfort, and cognitive performance. From ultrafine particles to toxic gases, traffic emissions release a dangerous mix of pollutants. Here’s what’s entering homes near busy roads. What pollutants come from road traffic Traffic emissions are a complex cocktail of gases and particles. Some are emitted directly from engines, while others come from the wear and tear of driving itself. The most concerning include: Ultrafine particles (UFPs): Smaller than 0.1 µm, these can penetrate deep into the lungs and even enter the bloodstream. Black carbon: A marker of diesel and gasoline combustion, strongly elevated near highways. Fine particulate matter (PM2.5): Less localized than UFPs but still harmful indoors. Nitrogen oxides (NO₂/NOₓ): Emitted by engines; linked to respiratory illness. Carbon monoxide (CO): Highest near dense traffic corridors. Volatile organic compounds (VOCs): Carcinogens like benzene and PAHs from fuel. Brake, tire and road-wear particles: Release metals like copper, zinc and iron. As IQAir CEO Frank Hammes said: “Traffic is one of the major pollution sources and tailpipe emissions are among the worst.” How far and how much pollution travels Pollution concentrations are strongest right next to the road, but still measurable hundreds of meters away. Steep gradients: UFPs, black carbon, NO₂ and CO typically fall sharply within 50–200 meters. Leveling out: By 300–500 meters, levels approach background, though weather and topography matter. PM2.5: Less variable but still elevated in near-road neighborhoods. Why traffic-related pollutants enter homes If outdoor air is polluted, why does it end up inside? In short: buildings breathe. Pressure differences from wind and temperature (the “stack effect”) pull outdoor air through the building envelope—around window frames and door seals, through vents and gaps in construction, and via any HVAC system that brings in outside air for ventilation. Even when windows are closed, this slow, continuous exchange can carry roadway pollution indoors (3). Ultrafine particles are especially tricky. Because they’re smaller than 0.1 µm, they slip through tiny cracks and stay suspended in indoor air for hours, drifting from room to room and settling into fabrics and dust (4). Gases like NO₂ and VOCs can also infiltrate and spread quickly through shared ducts or open floor plans. Indoor sources can compound the problem. Cooking (especially on gas stoves), smoking, burning candles or incense, and some cleaning products add their own particles and VOCs to the air. When indoor sources stack on top of outdoor infiltration, overall exposure rises—making indoor air quality highly dependent on both the conditions outside and the way a building is sealed, ventilated, and used. The role of monitoring You can’t fix what you don’t measure. Air quality monitoring — both indoors and outdoors — is essential to understanding exposure to pollution.

Po Valley will host the upcoming Winter Olympics when pollution is at its peak. What can be done to ensure athlete and spectator safety?

","In February 2026, Milan, Italy and the surrounding Po Valley will host the Winter Olympics, a global celebration of athletic excellence set against one of Europe’s most persistent winter air quality challenges. The Po Valley in northern Italy routinely experiences winter smog. This intersection of Olympic athletic competition and poor air quality raises concerns for the health and performance of both athletes and spectators. Where will the 2026 Olympic games be held? The 2026 Milan-Cortina Winter Olympic games will be held in three northern provinces of Italy – Lombardy, South Tyrol, and Veneto from February 6 through 22 (1). While most of the stadiums, arenas, and parks are in the surrounding Alps, the two largest participating cities – Milan and Verona – lie in the Po Valley. Five arenas and stadiums in Milan will host indoor-only events and the opening ceremony, while Verona Olympic Arena will host the closing ceremonies. Other venue locations include: Anterselva / Antholz, South Tyrol Bormio, Lombardy Cortina d’Ampezzo, Veneto Livigno, Lombardy Predazzo, Trentino Tesero, Trentino All locations, with the exceptions of Tesero and Verona, will house Olympic Villages where athletes will reside during the games. Why is the Po Valley’s air quality poor in winter? The Po Valley’s unique geography plays a central role in trapping pollutants: the valley is hemmed in by the Alps to the north and the Apennine Mountains to the south, creating a natural basin that traps cold air and pollutants. This \"bowl effect\" is compounded by meteorological conditions, particularly in winter, when temperature inversions occur. During these inversions, a layer of warm air settles above the cooler air near the ground, acting like a lid that prevents pollutants from dispersing upward or outward. As a result, pollutants can linger over the valley for days or even weeks. Human activity degrades the region’s poor air quality. Human activity affects the region’s air quality. The Po Valley is home to some of Italy’s most industrialized areas, where factories release PM2.5 – particulate matter measuring 2.5 micrometers in diameter or smaller – and nitrogen oxides (NO2) (2). Agriculture also contributes pollutants, as livestock farming produces ammonia, which reacts with industrial and vehicle emissions to create secondary particulate matter. According to a 2024 study, livestock farming may be responsible for as much as a quarter of Lombardy’s air pollution (3). Smoke from residential wood burning impacts winter air quality in the Po Valley (4). Vehicle emissions, particularly in major cities like Milan and Turin, are also sources of nitrogen dioxide and PM2.5 (5). These geographic and emissions-related factors are reflected in Milan’s long-term air quality data—but annual averages can mask the severity of winter pollution. In 2024, Milan's annual average PM2.5 concentration was 17 µg/m3. This was 3.4 times the WHO annual guideline of 5 µg/m3. However, this figure blends relatively cleaner summer conditions with much higher winter concentrations. During peak winter months, pollution levels rise sharply. In February 2025, Milan’s average monthly PM2.5 concentration was 32.1 µg/m3. These winter pollution episodes are often driven by stagnant air and temperature inversions rather than predictable daily emission cycles. Air quality in surrounding Alpine valleys may also be affected by residential wood burning combined with inversion conditions (6). Air quality lessons from past Olympics Previous Olympic host countries have struggled with poor air quality and have had to take measures to ensure health and safety. Beijing, China faced the potential for severe air pollution while hosting the 2008 Summer Olympics – and officials took proactive measures. In the months leading up to the Games, the U.S. Embassy in Beijing installed a regulatory-grade air quality monitor that exposed hazardous air quality in the city. Chinese authorities enacted sweeping temporary measures, including shutting down factories, and restricting vehicle traffic. Chinese officials implemented a robust policy shift in 2013, a year of terrible air quality for the country. The official policy response focused on long term air quality improvements – tougher coal-fired plant emissions standards, further vehicle restrictions, and initiatives to cut coal-fired home heating with electric or gas heaters (7). By the 2022 Beijing Winter Olympics, air pollution in the city was half that of both 2008 and 2013 (8). Rio de Janeiro was confronted with its own environmental crisis during the 2016 Olympics. While polluted water dominated the headlines, air quality also remained a persistent concern due to rapid development and 2.7 million vehicles in the city (9). To test those concerns, the Reuters news agency tested air quality at several Olympic sites across the city, finding a peak 24-hour average PM2.5 concentration of 65 µg/m3 at the Olympic Stadium (10). The WHO air quality guideline for an average 24-hour PM2.5 is 15 µg/m3. How winter smog can affect athletes Air pollution impacts the health and performance of those at the heart of the Olympics: the athletes. For endurance sports like cross-country skiing and biathlon, where athletes push their bodies to the limit for extended periods, polluted air reduces oxygen uptake and impairs lung function (11). Rapidly breathing in particulate matter can carry significant risks. Rapidly breathing in particulate matter can carry health risks. PM2.5 pollution penetrates deep into the lungs, triggering inflammation and narrowing airways, which can decrease stamina and slow recovery. Even short-term exposure during competition can lead to coughing, wheezing, and reduced athletic performance.

In February 2026, Milan, Italy and the surrounding Po Valley will host the Winter Olympics, a global celebration of athletic excellence set against one of Europe’s most persistent winter air quality challenges.

The Po Valley in northern Italy routinely experiences winter smog. This intersection of Olympic athletic competition and poor air quality raises concerns for the health and performance of both athletes and spectators.

Where will the 2026 Olympic games be held?

The 2026 Milan-Cortina Winter Olympic games will be held in three northern provinces of Italy – Lombardy, South Tyrol, and Veneto from February 6 through 22 (1). While most of the stadiums, arenas, and parks are in the surrounding Alps, the two largest participating cities – Milan and Verona – lie in the Po Valley. Five arenas and stadiums in Milan will host indoor-only events and the opening ceremony, while Verona Olympic Arena will host the closing ceremonies.

Other venue locations include:

Anterselva / Antholz, South Tyrol
\n
\nBormio, Lombardy
\n
Cortina d’Ampezzo, Veneto
\n
\nLivigno, Lombardy
\n
Predazzo, Trentino
\n
Tesero, Trentino
\n

All locations, with the exceptions of Tesero and Verona, will house Olympic Villages where athletes will reside during the games.

Why is the Po Valley’s air quality poor in winter?

The Po Valley’s unique geography plays a central role in trapping pollutants: the valley is hemmed in by the Alps to the north and the Apennine Mountains to the south, creating a natural basin that traps cold air and pollutants.

This \"bowl effect\" is compounded by meteorological conditions, particularly in winter, when temperature inversions occur. During these inversions, a layer of warm air settles above the cooler air near the ground, acting like a lid that prevents pollutants from dispersing upward or outward. As a result, pollutants can linger over the valley for days or even weeks.

Human activity degrades the region’s poor air quality.

Human activity affects the region’s air quality. The Po Valley is home to some of Italy’s most industrialized areas, where factories release PM2.5 – particulate matter measuring 2.5 micrometers in diameter or smaller – and nitrogen oxides (NO2) (2).

Agriculture also contributes pollutants, as livestock farming produces ammonia, which reacts with industrial and vehicle emissions to create secondary particulate matter. According to a 2024 study, livestock farming may be responsible for as much as a quarter of Lombardy’s air pollution (3).

Smoke from residential wood burning impacts winter air quality in the Po Valley (4). Vehicle emissions, particularly in major cities like Milan and Turin, are also sources of nitrogen dioxide and PM2.5 (5). These geographic and emissions-related factors are reflected in Milan’s long-term air quality data—but annual averages can mask the severity of winter pollution.

In 2024, Milan's annual average PM2.5 concentration was 17 µg/m3. This was 3.4 times the WHO annual guideline of 5 µg/m3. However, this figure blends relatively cleaner summer conditions with much higher winter concentrations.

During peak winter months, pollution levels rise sharply. In February 2025, Milan’s average monthly PM2.5 concentration was 32.1 µg/m3.

These winter pollution episodes are often driven by stagnant air and temperature inversions rather than predictable daily emission cycles. Air quality in surrounding Alpine valleys may also be affected by residential wood burning combined with inversion conditions (6).

Air quality lessons from past Olympics

Previous Olympic host countries have struggled with poor air quality and have had to take measures to ensure health and safety.

Beijing, China faced the potential for severe air pollution while hosting the 2008 Summer Olympics – and officials took proactive measures. In the months leading up to the Games, the U.S. Embassy in Beijing installed a regulatory-grade air quality monitor that exposed hazardous air quality in the city. Chinese authorities enacted sweeping temporary measures, including shutting down factories, and restricting vehicle traffic.

Chinese officials implemented a robust policy shift in 2013, a year of terrible air quality for the country. The official policy response focused on long term air quality improvements – tougher coal-fired plant emissions standards, further vehicle restrictions, and initiatives to cut coal-fired home heating with electric or gas heaters (7). By the 2022 Beijing Winter Olympics, air pollution in the city was half that of both 2008 and 2013 (8).

Rio de Janeiro was confronted with its own environmental crisis during the 2016 Olympics. While polluted water dominated the headlines, air quality also remained a persistent concern due to rapid development and 2.7 million vehicles in the city (9). To test those concerns, the Reuters news agency tested air quality at several Olympic sites across the city, finding a peak 24-hour average PM2.5 concentration of 65 µg/m3 at the Olympic Stadium (10). The WHO air quality guideline for an average 24-hour PM2.5 is 15 µg/m3.

How winter smog can affect athletes
\n

Air pollution impacts the health and performance of those at the heart of the Olympics: the athletes.

For endurance sports like cross-country skiing and biathlon, where athletes push their bodies to the limit for extended periods, polluted air reduces oxygen uptake and impairs lung function (11).

Rapidly breathing in particulate matter can carry significant risks.

Rapidly breathing in particulate matter can carry health risks. PM2.5 pollution penetrates deep into the lungs, triggering inflammation and narrowing airways, which can decrease stamina and slow recovery. Even short-term exposure during competition can lead to coughing, wheezing, and reduced athletic performance.

High-intensity sports, such as ice hockey and speed skating, are also affected, as the increased respiratory rate during exertion means athletes inhale more pollutants, further straining their cardiovascular and respiratory systems.

How winter smog affects spectators

Vulnerable spectators—children, the elderly, and individuals with pre-existing conditions like asthma—face heightened risks of respiratory distress when exposed to air quality in the “unhealthy for sensitive groups” range.

Outdoor venues, where events like ski jumps, open-air ceremonies, and marathon-style races take place, present the greatest exposure, as there is no barrier between the crowd and air pollution. Even indoor events may not offer full protection, as pollutants can seep inside or accumulate in poorly ventilated spaces.

Po Valley residents have been demonstrably susceptible to winter air quality health risks. A study found that the highest mortality burden for European cities in 2015 was in the Po Valley, Poland, and the Czech Republic (12).

And a 2025 study uncovered that infants in Northern Italy with medium-term exposure to high concentrations of pollutants experienced a greater risk of acute bronchiolitis (13).

Local air pollution sources Localized air pollution sources and air pollution concentrations over time can vary dramatically from building to building based on location and operating hours. For example, office buildings near busy streets or highways may experience their highest levels of air pollution during morning and afternoon vehicle traffic. Vehicle exhaust is a major source of PM2.5, ultrafine particles (UFPs), chemicals, and volatile organic compounds (VOCs).1,2 Air filtration must be designed not only to help reduce outdoor air pollution that can seep indoors but also remove indoor air pollutants from furnishings, construction materials, and personal hygiene products that can impact employee health and productivity.

Despite the age of a building, our Solutions Engineers can design filtration solutions that can be retrofitted into existing heating, ventilation, and air conditioning (HVAC) systems or customize stand-alone solutions for any facility. Expert consultation Evaluations (onsite or virtual) by subject matter experts in commercial air quality and air filtration systems can help simplify this process through the following steps: Building walkthrough: Facility construction, HVAC systems, and existing air filtration (if applicable) are documented. Spot measurements of ambient air quality: Major sources of air pollution, both indoors and outdoors, are documented using high-accuracy air quality monitoring tools. Inspection of air handlers and air distribution: Current facility HVAC and air filtration technology, including outstanding maintenance and upgrades, are noted. Detailed analysis: A written report is shared with facility stakeholders, describing air quality issues and suggesting customized air filtration solutions to help the building meet Clean Air Facility requirements. Based on evaluation results, one or more of the following solutions may be proposed: HVAC air filtration: For many buildings, HVAC air filtration is the most logical choice for air pollution mitigation. This type of air quality solution uses centralized airflow and filtration mechanisms to help deliver clean air to the entire building through facility ductwork. Localized air filtration solutions: Stand-alone air purifiers or room air purifiers can provide clean air to workspaces that may not have access to a centralized HVAC system or may be required depending on the day to day activities that take place within the facility. A high-performance system can provide several air changes per hour (ACH) and filter up to 99.5% of airborne particles in any given workspace. Individualized air purification: Personal air purifiers can help shield employees at individual workstations from air pollutants and airborne infections, delivering clean air filtered from up to 99% of airborne particles directly to a person’s breathing zone. Many buildings have traditionally relied on HVAC air filters rated MERV 13 or lower according to the MERV efficiency system based on the ASHRAE 52.2 standard.6 However, MERV 13 is tested to capture up to 50% of airborne particles ranging from 0.3-1.0 microns in size. This can leave up to half of the most dangerous airborne particles unfiltered, including airborne infections and ultrafine particles (UFPs). MERV 13 filters also require extensive mechanical ventilation to effectively dilute indoor concentrations of airborne particles. This can negatively affect a building in two ways: increased penetration of outdoor air can reduce building energy efficiency by disrupting indoor climate control and requiring increased HVAC operation hours for thermal comfort ventilation with outdoor air can bring in outdoor air pollutants that can cause poor indoor air quality, reducing the efficiency of air filtration systems IQAir filtration technology provides high-efficiency HVAC panel filters with ultralow pressure drop. In fact, NanoMax filtration technology exceeds MERV 16 standards with only the pressure drop of an average MERV 8 filter. NanoMax filters are suggested as an alternative to counter these potential downsides of traditional MERV 13 air filters. NanoMax filters are tested to capture up to 96 percent of airborne particles between 0.3-1.0 microns and at least 90% of UFPs less than 0.1 microns.7 Their high efficiency eliminates the need for additional mechanical ventilation beyond building code requirements. The high efficiency of NanoMax filters reduces the need for additional mechanical ventilation beyond building code requirements. Refer to the table below for a side-by-side comparison of filtration efficiencies for MERV 13 air filters and NanoMax air filters. Microns MERV 13 NanoMax Estimated Improvement with NanoMax 3-10 microns up to 90% up to 100% ~11% 1-3 microns 80-85% up to 99% Up to 24% 0.3-1 micron ≤ 50% up to 96% Up to 174% < 0.1 micron Not tested 90% Substantial Fewer HVAC filter changes NanoMax filters require fewer filter replacements over time. This can significantly reduce the costs associated with filter purchases and labor involved in filter replacements. Refer to the table below for an example of cost savings with NanoMax in comparison to MERV 13 filters for a facility using 50 NanoMax filters. Filter Type Filter Replacement Intervals * Yearly Maintenance Hours (15 min./filter) Yearly Filter Costs MERV 13 4 times per year 50 hours $2,000-$8,000 NanoMax (exceed MERV 16 performance) 1 time per year 12.5 hours $5,000 * based on 8 hours of HVAC operation per day (2,920 hours). Energy management Unlike many traditional MERV 13 air filtration systems, NanoMax HVAC air filters used as part of the Clean Air Facility program do not require additional mechanical ventilation beyond what is required per building code. As a result, buildings can only operate HVAC air filtration systems as needed to reduce energy usage. This helps minimize a building’s carbon footprint while maintaining 90 to 100 percent air filtration efficiency for particles while the building is occupied and HVAC systems are operating. Air quality monitoring and smart technology Smart indoor climate systems and other building control systems can also be paired with indoor and outdoor air quality monitoring to automate HVAC air filtration systems using preset protocols: HVAC Systems: Program smart thermostats to maintain energy-efficient “Fan On” mode and deliver clean air even in the absence of heating or cooling operations. High-Capacity Stand-Alone Systems: Pair air purifiers with occupancy sensors, timers, or air quality monitors so that systems operate when indoor spaces are occupied or indoor air pollution concentrations surpass pre-programmed thresholds. Air quality verification and monitoring The impact of PM2.5 and indoor gases like carbon dioxide (CO2) on employee health, productivity, and cognitive performance has long been documented.8,9,10,11 Air quality monitoring can provide crucial data to help ensure that HVAC systems supplies sufficient levels of clean and oxygenated air to occupants and reduce the health impacts of air pollution and airborne infections. You will receive an air quality report every month for your facility. You will be contacted within 4 business hours if there is an issue with your facility’s air quality. Public air quality data displays can also demonstrate to building inhabitants the immediate benefits of indoor clean air, especially when outdoor air pollution is heavy. This data can be displayed on publicly visible TV monitors or on company websites using customizable air quality data widgets (see Figure 1 for an example).

On-site air quality assessment The first step toward clean air at school is a thorough evaluation and assessment (virtual or in-person) of the school site. As you begin to determine your school’s air quality needs, several critical factors must be considered to identify specific air quality challenges and possible solutions. Local sources of pollution The degree to which your school is affected by air pollution is a major factor in determining your specific air filtration needs and how extensive filtration technology may be throughout your school site. Schools located near highways, busy roads, or heavy industrial polluters like factories or ports may face higher levels of PM2.5,(particulate matter with a diameter size of 2.5 microns or smaller), ultrafine particles (UFPs), and chemicals that can be difficult to control. Click here to see why particle size matters... Air pollution and COVID-19 (a serious disease, often fatal, that is caused by the SARS-CoV-2 virus)outcomes are also closely linked. Common air pollutants, especially PM2.5, may increase the risk of illness or death from COVID-19. In these cases, air filtration that can adequately address high volumes of both indoor and outdoor air pollution are necessary. School age and HVAC design The average school building in the United States is between 37 and 46 years old (1) (2).Heating, ventilation, and air conditioning (HVAC) design has changed dramatically during this period. Some schools have central HVAC systems, while others may have individual heating and cooling units for every classroom. This can drastically alter the air filtration needs from school to school. Maintenance Maintenance and filter replacement are key to long-term air filtration performance. Proper installation and filter replacements must both be taken into account when budgeting for long-term air filtration needs. Air pollution sources and HVAC system design both affect the type of solution you’ll need as well as how often you’ll need to replace filters. Schools in heavily polluted areas may require more frequent filter replacements as filters quickly build up with airborne particles.

A high-performance system can provide several full air changes per hour (ACH), removing up to 99.5% of airborne particles in a classroom. Personal air purifiers can also help by providing individual desks and workstations with a direct supply of clean air, delivering air filtration efficiencies up to 99% for airborne particles. However, customized minimum efficiency reporting value (MERV)16 HVAC air filtration is recommended to capture infectious particles and pollutants across the largest area possible. MERV 13 filtration is currently a popular choice for filtration in schools. But MERV 13 only captures up to 50% of airborne particles between 0.3-1.0 microns. MERV 13, due to its lower efficiency, might require extensive mechanical ventilation. This reduces energy efficiency and may not be feasible during extreme weather. MERV 16 is nearly twice as efficient as MERV 13, capturing up to 95% of airborne particles in the 0.3-1.0 micron range. MERV 16 is nearly twice as efficient as MERV 13, capturing up to 95% of airborne particles in the 0.3-1.0 micron range (see Figure 1) and requiring little to no ventilation (3). Figure 1: MERV air filtration efficiency for different particle sizes. MERV 16 efficiencies are detailed at the bottom of the chart (Source: ASHRAE Standard 52.2-2017) (4). During field tests in classrooms, MERV 16 filtration has met and even exceeded these efficiency ratings (5). 2.

HVAC upgrades HVAC systems are sometimes outdated, inefficient, or incompatible with MERV 16 technology. System upgrades and custom installation plans may be necessary to achieve the maximum filtration capabilities and protection from airborne infections. Energy management Unlike MERV 13, MERV 16 systems do not require 100% ventilation to filter indoor air pollutants. This means that your HVAC system can be turned on and off as needed to save energy. Reduced ventilation can also reduce your school’s carbon footprint while still achieving up to 95% filtration efficiency and protecting classrooms from outdoor air pollution (6). Smart thermostats and other energy management systems can help your school program air filtration systems for use during school hours when students are in class. Air quality monitoring and smart technology Air quality monitoring coupled with smart technology, such as smart thermostats, can help automate filtration behavior with predetermined protocols: HVAC Systems: Smart thermostats are programmed to keep HVAC on “Fan On” mode for clean air even when cooling or heating are off.

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

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

\nModerately Unhealthy (51–100): Pollutants may affect breathing even in healthy individuals. Consider exercising indoors or keeping outdoor workouts shorter and less intense.
\nUnhealthy for Sensitive Groups (101–150): Everyone may be affected, especially those with heart or lung conditions. Indoor exercise is the safer choice.
\nVery Unhealthy (151–200): Health effects are more likely for everyone. Avoid outdoor exercise.
\nHazardous (201–500): Air quality is poor enough to pose serious health risks. Stay indoors and avoid physical exertion.

Using these ranges helps shift workouts to safer times, locations, or environments—without avoiding exercise altogether.

Using air quality data to plan your workouts

Air quality can change quickly due to traffic patterns, weather, and human activity. Pollution levels that are low early in the day may rise within hours, particularly during rush hour or in enclosed indoor spaces with high occupancy.

Checking real-time air quality data and short-term forecasts helps you decide when and where to exercise with less exposure.

Monitoring pollutants like PM2.5 and carbon dioxide allows you to adjust workout timing, intensity, or location accordingly—such as exercising earlier, choosing a less crowded space, or prioritizing indoor workouts when outdoor air quality is poor.

Indoor vs. Outdoor Exercise: Which Is Better?

When air quality is poor, the choice between exercising indoors or outdoors isn’t always straightforward. Outdoor workouts may offer better airflow, but they also expose you directly to pollution from traffic, industry, wildfire smoke, and other airborne contaminants.

Indoor exercise can reduce exposure when ventilation and filtration are adequate, but poorly ventilated gyms or studios can allow pollutants like PM2.5 to accumulate—especially during busy classes or peak hours.

In general, the better option depends on conditions:

When outdoor air quality is good, exercising outside or ventilating indoor spaces can be beneficial.
When outdoor air quality is poor, well-filtered and properly ventilated indoor environments are often the safer choice.

Monitoring air quality both indoors and outdoors helps you choose the option that minimizes exposure while still supporting your fitness goals.

\nHow to exercise safely indoors
\n

Indoor exercise can be made safer with a few practical adjustments. Paying attention to ventilation, filtration, and air quality helps reduce unnecessary exposure during workouts.

Choosing a gym or fitness studio:

Prioritize facilities with high performance air purifiers.
Ask staff about their ventilation systems and cleaning protocols. Gyms using green-certified products and frequent air exchanges are safer bets.
Consider outdoor workouts when possible, if the air quality is good. Parks or open-air studios provide better airflow than indoor studios.
\nDownload a free air quality app to know what the air is like before you go outdoors to exercise.

At home:

Use an indoor air quality monitor to track PM2.5 and CO2 levels in real time.
Use in tandem with an outdoor air quality monitor to know when outdoor air could impact indoor air quality.
Open windows when outdoor air quality is good. Close them when it is poor.
Avoid exercising near high-traffic hours or in areas with heavy cleaning fumes.

\nConclusions\n

Clean air is a non-negotiable component of an effective workout. By choosing cleaner spaces, monitoring air quality, and pushing for better standards, you can breathe easier and perform better.

Take a breath during your next workout—and make sure it’s a clean one.

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

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