See why Dr. Stanely, a tireless advocate for systemic healthcare, invested in high performance air filtration for his world-renowned dental clinic.

","content","Dr. Miguel Stanley is the founder and clinical director of the White Clinic in Lisbon, Portugal (1). His patients travel to him from around the world; among his clients are famous athletes and celebrities. “I'm an old school dentist doing advanced integrative dentistry,” he said. “One of the fastest growing trends in dentistry is connecting the mouth to the rest of the body.” – Dr. Miguel Stanley When he’s not doing clinical work, Dr. Stanley advocates and educates both colleagues and the public on the crucial role oral health plays in our overall health, and has lectured in over 50 countries (2). As the co-founder the Slow Dentistry Global Network, Dr. Stanley is dedicated to bettering the safety and experience of patients around the globe. And as an adjunct professor at the University of Pennsylvania School of Dentistry, he’s noted hundreds of keynote lectures given over the course of 25 years. Around 2018, Dr. Stanley decided to transition his private practice towards integrative healthcare. “One of the fastest growing trends in dentistry is connecting the mouth to the rest of the body.” In line with this trend of comprehensive health care, Dr. Stanley incorporated many advanced technologies including IQAir’s advanced air filtration systems to enhance the overall wellness environment within his clinic. State-of-the-Art equipment for enhanced patient care The White Clinic boasts a wide array of equipment, ranging from hyperbaric oxygen therapy (HBOT) to Low-Level Laser Therapy (LLLT), and cryotherapy and hydrogen inhalation for wound-healing and pain relief. Yet there was one technology Dr. Stanley wanted to invest in to improve not only the well-being of his patients but also himself and his staff at the clinic. Dr. Stanley's commitment to advanced dental care extends beyond cosmetic enhancements; he sees oral health as a window to overall wellness. This perspective is why he eventually incorporated IQAir’s air filtration technologies—because clean air in the clinic does more than protect against immediate contaminants; it’s integral to holistic health outcomes. IQAir: An essential addition As the global pandemic sparked shutdowns and quarantines, Dr. Stanley’s clinic was the first dental clinic in Portugal to close its doors for safety. He understood that he’d need a practical solution for keeping his patients and staff safe. IQAir’s reputation for excellence stood out to him. “I trust Swiss tech a lot. I've always invested in quality, and I hold the belief that if it's something that is important to you, you have to buy the best.” Dr. Stanley purchased four IQAir CleanZone systems for his clinic. Armed with IQAir’s patented HyperHEPA filtration technology (far superior to standard HEPA filters and proven to trap more than 99.5% of particles down to 0.003 microns—a level of filtration crucial in dental clinics), the White Clinic would be well-protected from bacteria and viruses like SARS-CoV-2. “IQAir filtration became an essential part of our medical armamentarium.” “IQAir filtration became an essential part of our medical armamentarium throughout dental procedures and improved the air quality for everyone in the room. We use it for our laser surgery to filler aerosols as well as mercury amalgam removal under the SMART protocol,” Dr. Stanley said. Seeing the clean air difference In his medical advocacy, Dr. Stanley notes that it’s essential for dentists to always place safety first in their practices. This is foundational for Slow Dentistry. Doctors, surgeons, and dentists all generate aerosols in their practice. From chemical disinfectants to higher-than-average levels of inorganic mercury (Hg), there is demonstrable increased risk of poor health impacts from aerosolized pollutants. Extraoral suction and negative pressure equipment, which Dr. Stanley invested in during dental treatments, is a central component to safe, effective dentistry. But beyond his immediate practice needs, he wanted to elevate the air quality in his practice to the highest possible standard. Dr. Stanley runs his IQAir systems at the highest possible setting. And in his practice, he can actually see the systems working to keep him and his team safe. Aerosols that could impact his safety are visible. “I use and Er-Yag laser for surgery and because I also use Zeiss microscope magnification with LED light, I can see this cloud of aerosols magnified. I can really see it's being sucked into the IQAir tube. I can actually see it, so I'm not feeling it. That is worth gold to me.” Safe, effective air cleaning technology, Dr. Stanley feels, is essential for a wide variety of medical settings. “Adopting IQAir’s filtration technology has been a game-changer, ensuring that our practice not only meets but exceeds health and safety standards. This technology is pivotal and should become a standard in dental practices worldwide for its undeniable benefits in protecting both patients and staff.” “This technology is pivotal and should become a standard in dental practices worldwide for its undeniable benefits in protecting both patients and staff.” The future of dentistry Dr. Stanley’s advocacy and grounding in systemic healthcare, connecting all aspects of the body to better health outcomes and great longevity, is a fundamental aspect of his practice. \"I envision a future where everyone understands the true foundations of longevity—embracing simple, vital practices like healthy eating, sound sleep, and avoiding harmful habits.” Dr Stanley has also recently developed MissingLink, an AI platform that can scan dental X-rays and looking for hidden pathologies that patients can also use. As Dr. Stanley said, “Its a simple tool that connects doctors to dentists.” Conclusion By investing in IQAir’s advanced air purification systems, Dr. Stanley extends his holistic health philosophy into every aspect of his practice, thus safeguarding both patients and staff against airborne pollutants. He would love to see more patients take an active role in their own healthcare, and to better understand how systemic healthcare care improve longevity and healthful living. Part of that solution requires access to clean, healthy air. He encourages other dentists to investigate high performance air filtration for their practices as well. And he was satisfied with his own investment in IQAir filtration. “They're very robust, very trustworthy, and the price and quality are amazing.”","contentHtml","

Air quality in dental practices Why should you be concerned about the air quality in your dental practice? Dental practices and operatories experience specific air quality problems that can expose dentists, hygienists, and patients to infectious airborne pathogens, such as biological contaminants and viruses, as well as other unhealthy pollutants like chemicals, volatile organic compounds (VOCs), and ultrafine particles produced from high-speed instruments.1 According to Dental Research Journal and the United States Department of Labor, dental work is one of the most hazardous occupations because of high risk of exposure to infections like COVID-19, toxic substances, and radiation for dentists, hygienists, and patients.2,3 Here are some of the possible air quality hazards that a dental worker or patient can face in a dental practice or operatory: viral infections from splattering liquid, droplets, or aerosols from high-speed drilling and cleaning instruments that can carry viral material for viruses like COVID-19, human immunodeficiency virus (HIV), and hepatitis B biological contaminants, such as bacteria, that can be spread through airborne dental aerosols, improperly sterilized tools and surfaces, or from close, direct contact with a patient with an active bacterial infection, such as tuberculosis and syphilis allergies to substances in dental tools and equipment, such as latex in gloves, detergents used to clean equipment, and chemicals used to develop X-rays chemicals from disinfectants and cleaning supplies used to sterilize tools and the dental practice environment airborne mercury vapor from amalgam filling removal and disposal that can cause respiratory and neurological damage (less common in modern dental practices) Extra oral suction system and infection control Extra oral suction systems are an important first-line defense in ensuring that any dental aerosols carrying infected viral or bacterial matter are captured at the source – the patient’s mouth – when they result from high-speed instrumentation procedures that increase the concentration of airborne aerosols. High-speed dental instruments, such as those used for cavity drilling and ultrasonic scaling techniques during cleanings, often generate millions of microscopic dental aerosols and tiny micro-droplets that can contain highly infectious bacterial or viral pathogens from the patient’s mouth, including COVID-19.4,5 Once airborne, these aerosols and droplets can make contact with the clothes of patients, hygienists, staff, and dentists. These infected particles can stay on clothing for up to several days. This increases the risk that infectious pathogens are transferred from clothes into the respiratory system when, for example, a dental worker touches their face. Airborne aerosols can also remain in the air for hours before bacterial or viral material settles on surfaces. While they’re airborne, aerosols can also be inhaled by anyone in the dental practice and cause respiratory infections, such as COVID-19. As a result, the American Dental Hygienists’ Association has recommended that aerosol-producing procedures should be avoided whenever possible.6 Mercury Modern mercury (Hg) removal techniques and newer, non-mercury filling materials have reduced the exposure of many dental workers and patients to harmful mercury vapor toxins. The Occupational Safety and Health Administration (OSHA) establishes the absolute permissible exposure limit (PEL) to mercury at 0.1 milligrams per cubic meter of air (mg/m³). The National Institute for Occupational Safety and Health (NIOSH) recommends exposure to no more than 0.5 mg/m³ during a 10-hour workday.7,8 But studies suggest that many dentists and their staff still experience exposure to mercury beyond these safe levels. This is primarily because of the continued practice of removing amalgam fillings and, in some cases, placing new amalgam fillings. As a result, dentists and their staff have consistent, prolonged exposure to mercury that’s settled on surfaces throughout the dental practice from years of use as well as to mercury vapor that can be inhaled during mercury removal procedures that involve high-speed drilling. Prolonged exposure leads to demonstrably higher than average levels of inorganic mercury in the blood and urine of dentists and their staff. Over time, inhalation of mercury can increase the risk of harm to the digestive, nervous, and immune system as well as kidney and cognitive dysfunction. According to the World Health Organization (WHO), exposure to levels of airborne mercury vapor around 20 μg/m3 over a period of years can cause nervous system toxicity and kidney conditions, including kidney failure.9 Disinfectants Disinfectants are critical to keeping a dental practice clean, especially from infectious viruses like COVID-19 that can spread through contact with surfaces.10 Disinfectants are also important for sterilizing dental unit water lines (DUWL) used in cleanings, where bacteria can build up in thin layers called biofilms.11 But disinfectant chemicals, such as glutaraldehyde and peracetic acid, can produce volatile organic compounds (VOCs) that result in unpleasant odors. And over time, exposure to VOCs can result in chemical sensitivity that can produce severe symptoms in both staff and patients, including skin irritation (dermatitis) and asthma.12 This sensitivity can also reduce immune system function and increase dental worker risk for COVID-19 and other airborne infections in dental practices.13 Air purifier for dental practices IQAir Dental Series air purifiers for dental practices are rated as the best air purifiers for dental practices, designed for a wide range of air cleaning needs in dental practices, including extra oral suction systems, infection control, and customizable modules that can enable dentists to create negative pressure environments in the dental practice during procedures where aerosols, mercury, and other infectious material can become airborne.

Air quality in dental practices

Why should you be concerned about the air quality in your dental practice?

Dental practices and operatories experience specific air quality problems that can expose dentists, hygienists, and patients to infectious airborne pathogens, such as biological contaminants and viruses, as well as other unhealthy pollutants like chemicals, volatile organic compounds (VOCs), and ultrafine particles produced from high-speed instruments.¹

According to Dental Research Journal and the United States Department of Labor, dental work is one of the most hazardous occupations because of high risk of exposure to infections like COVID-19, toxic substances, and radiation for dentists, hygienists, and patients.^2,3

Here are some of the possible air quality hazards that a dental worker or patient can face in a dental practice or operatory:

viral infections from splattering liquid, droplets, or aerosols from high-speed drilling and cleaning instruments that can carry viral material for viruses like COVID-19, human immunodeficiency virus (HIV), and hepatitis B
biological contaminants, such as bacteria, that can be spread through airborne dental aerosols, improperly sterilized tools and surfaces, or from close, direct contact with a patient with an active bacterial infection, such as tuberculosis and syphilis
allergies to substances in dental tools and equipment, such as latex in gloves, detergents used to clean equipment, and chemicals used to develop X-rays
chemicals from disinfectants and cleaning supplies used to sterilize tools and the dental practice environment
airborne mercury vapor from amalgam filling removal and disposal that can cause respiratory and neurological damage (less common in modern dental practices)

Extra oral suction system and infection control

Extra oral suction systems are an important first-line defense in ensuring that any dental aerosols carrying infected viral or bacterial matter are captured at the source – the patient’s mouth – when they result from high-speed instrumentation procedures that increase the concentration of airborne aerosols.

High-speed dental instruments, such as those used for cavity drilling and ultrasonic scaling techniques during cleanings, often generate millions of microscopic dental aerosols and tiny micro-droplets that can contain highly infectious bacterial or viral pathogens from the patient’s mouth, including COVID-19.^4,5

Once airborne, these aerosols and droplets can make contact with the clothes of patients, hygienists, staff, and dentists.

These infected particles can stay on clothing for up to several days. This increases the risk that infectious pathogens are transferred from clothes into the respiratory system when, for example, a dental worker touches their face.

Airborne aerosols can also remain in the air for hours before bacterial or viral material settles on surfaces.

While they’re airborne, aerosols can also be inhaled by anyone in the dental practice and cause respiratory infections, such as COVID-19. As a result, the American Dental Hygienists’ Association has recommended that aerosol-producing procedures should be avoided whenever possible.⁶

An innovator

Dr. Blodgett became the first dentist in the State of Oregon to be board certified in Naturopathic Medical Dentistry and Integrative Biological Dental Medicine.

And while he was becoming certified for SMART (safe mercury amalgam removal technique) by the International Academy of Oral Medicine and Toxicology (IAOMT), he heard about IQAir’s room air purifiers from some of the trade organization’s other members.

Mercury is a versatile, affordable filling known for its strength and durability. It isn’t used just by itself, though. It’s part of what’s called an amalgam, which means it’s a combination of metals, including silver, tin, copper and even small amounts of zinc, indium or palladium. Mercury is also commonly used in dental amalgam. With it, dental fillings become more pliable and, when mixed with an alloy powder, mercury helps create a compound soft enough for dentists to press into a tooth for a cavity filling. Mercury amalgam hardens quickly, and durably withstands the rigors of biting and chewing. Dentists place more than 1 billion mercury fillings in patients’ mouths each year.Do amalgams release mercury vapor?For decades it was believed that once mercury amalgam was dried in a tooth, no mercury was released into a person’s mouth. But researchers have discovered that small amounts of mercury vapor are released during normal filling wear. With more sophisticated scientific tests now available, researchers now know that amalgam fillings generate up to 27 micrograms of mercury vapor per day. The amount of mercury vapor released during dental procedures could result in levels of exposure that exceed government safety standards.Are dental staff at risk for mercury toxicity?Those who regularly work with mercury fillings are required to take precaution. Daily mercury exposure can cause build up and produce symptoms of toxicity. Studies have also shown that some dental staff have elevated levels of mercury in their bodies. The reason is mercury vapor. Elemental mercury liquefies at room temperature and easily vaporizes. Also, drilling and removing amalgam generates fine particles and vapor, then is easily absorbed into the lungs and nasal tissues.

A saliva ejector removes saliva from a patient’s mouth. High-volume suction device. This device helps keep the tooth dry. It also removes debris, such as mercury amalgam particles, as the dental drill dislodges them. High-suction dental tools, do not, however, control mercury vapor. How to remove mercury vapor from dentist’s officesBecause mercury can also be vaporous, dental offices are encouraged to take safety a step further by using an air purifying and filtration system. The IQAir Dental Series, for example, is designed to filter indoor air pollutants found in most dental offices. Dental pollutants include not only mercury vapor in the air, but also disinfectant smells, abrasion powder, drill aerosols, bacteria, viruses and volatile organic compounds (VOCs).A study conducted by the Institute of Hygiene at the University of Heidelberg concluded that IQAir air purifiers in dental offices effectively eliminate mercury vapors, formaldehyde, particulates, microorganisms and odors. The result is a cleaner, healthier dental office that’s safe for both patients and dental staff.","

There are two suction techniques to help reduce mercury vapor when drilling:

\nSaliva ejector. A saliva ejector removes saliva from a patient’s mouth.
\nHigh-volume suction device. This device helps keep the tooth dry. It also removes debris, such as mercury amalgam particles, as the dental drill dislodges them. High-suction dental tools, do not, however, control mercury vapor.

How to remove mercury vapor from dentist’s offices

Because mercury can also be vaporous, dental offices are encouraged to take safety a step further by using an air purifying and filtration system. The IQAir Dental Series, for example, is designed to filter indoor air pollutants found in most dental offices. Dental pollutants include not only mercury vapor in the air, but also disinfectant smells, abrasion powder, drill aerosols, bacteria, viruses and volatile organic compounds (VOCs).

A study conducted by the Institute of Hygiene at the University of Heidelberg concluded that IQAir air purifiers in dental offices effectively eliminate mercury vapors, formaldehyde, particulates, microorganisms and odors. The result is a cleaner, healthier dental office that’s safe for both patients and dental staff.

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

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

A stronger approach is one that removes pollutants without adding new ones to the room. Is its performance based on clear, testable standards? Look beyond broad marketing claims. CADR can help show how quickly a purifier reduces particles in a room under short-term test conditions, but it does not tell you how performance holds up over time.

A stronger air purifier claim is usually a simpler one: capture pollutants efficiently, move enough air, and maintain that performance over time. Conclusion A HyperHEPA air purifier is a filtration-based air purifier built to capture extremely small airborne particles—well beyond the particle-size range most people associate with standard HEPA. That makes it especially relevant in situations where ultrafine pollution matters, such as wildfire smoke, traffic emissions, and other combustion-related indoor air concerns.

Indoor air often contains a mix of pollutants that are easy to overlook—dust, pollen, smoke, and microscopic particles from traffic or combustion that can stay suspended in the air we breathe. For people with allergies, asthma, or respiratory sensitivities, reducing those particles indoors can make a noticeable difference in comfort and health.

A HyperHEPA air purifier is a filtration-based air purifier designed to capture particles far smaller than the size standard commonly associated with HEPA filtration. In simple terms, it is built for environments where reducing ultrafine airborne particles is especially important.

To understand why that matters, it helps to start with what standard HEPA filtration does well—and where higher-performance filtration can go further.

What is HEPA filtration?

HEPA (high-efficiency particulate air) filters are designed to trap 99.97% of particles as small as 0.3 microns, including dust, pollen, pet dander, and mold spores (1)(2).

Originally developed during World War II to contain radioactive particles, HEPA technology has since become the industry standard for air purification. It works by forcing air through a dense mat of fibers, where particles are captured through a combination of interception, impaction, and diffusion.

However, HEPA filters have limits. They struggle with ultrafine particles smaller than 0.3 microns, including some viruses and combustion particles. In real-world use, filtration performance also depends on the purifier’s design. If air can bypass the filter because of gaps or poor sealing, some polluted air may circulate without being filtered.

In real-world use, those limitations can matter most when the air contains large amounts of ultrafine pollution—such as wildfire smoke, traffic-related combustion particles, or other high-particle events. In those situations, filter performance depends not just on the filter media itself, but also on how well the overall system is sealed.

What is HyperHEPA filtration?

A HyperHEPA air purifier is an air purifier built with filtration media designed to capture 99.5% of particles down to 0.003 microns—100 times smaller than the 0.3-micron benchmark commonly associated with standard HEPA filtration.

That matters because many of the particles people worry about most indoors are extremely small. Ultrafine particles from combustion, traffic pollution, smoke, and some airborne biological material can behave differently from larger dust or pollen particles, staying suspended longer and reaching deeper into the respiratory system.

A HyperHEPA air purifier is not a different category of appliance from an air purifier—it is a higher-performance particle filtration approach within an air purifier. In practice, that means the purifier is designed not only around the filter media itself, but also around system sealing and airflow so that filtered air is less likely to bypass the filter.

Why ultrafine particles matter

Not all airborne particles behave the same way. Larger particles, like visible dust or some pollen, settle more quickly. Ultrafine particles are different: they are so small that they can stay airborne longer and move more easily through indoor spaces.

That’s one reason wildfire smoke, traffic emissions, and other combustion-related pollution can be so difficult to manage indoors.

Find out more about the Wellington flash floods impacting communities across New Zealand’s capital region.

","What is the location of the flooding? As of April 20, 2026, severe flash flooding is impacting Wellington, the capital of New Zealand, situated on the southern coast of the North Island. (1) The flooding has been driven by intense rainfall that has overwhelmed urban drainage systems and caused rivers and stormwater channels to overflow into surrounding neighborhoods. (2) The flooding is concentrated in low-lying urban areas, flood-prone suburbs, and regions near stormwater systems and coastal zones, with widespread impacts across the Wellington metropolitan area. Which cities or areas are affected by the flooding? The following cities and areas have been directly impacted by the flooding: Karori Kingston Lower Hutt Mornington Newtown Stokes Valley Wellington Whanganui District Floodwaters have impacted residential homes, roads, and infrastructure across these areas, with particularly severe impacts in southern and low-lying suburbs. (3) What is the current containment status of the flooding? As of April 20, 2026, the flooding is partially contained, with water levels receding in some areas while ongoing risks remain due to continued rainfall and saturated ground conditions. (4) Emergency crews are actively engaged in clean-up operations, debris removal, and response efforts. However, additional storms and heavy rain forecasts continue to pose a threat of further flooding. Are there any evacuation orders or alerts in place? Authorities have issued evacuation advisories for residents in low-lying and flood-prone areas, urging them to relocate to safer locations if conditions worsen and to avoid all non-essential travel. (5) Emergency shelters have been set up, including support services coordinated by the Wellington City Mission, to assist displaced residents. Officials have also warned the public not to walk or drive through floodwaters due to the risk of strong currents, hidden debris, and rapidly changing conditions. Emergency alerts remain in place as severe weather continues to pose risks, including further flooding and landslides. Emergency services have responded to a high number of incidents across the region, and residents are advised to stay informed through official updates and be prepared to act quickly if the situation escalates. How can I protect myself from mold after flooding? It’s important to take steps to prevent mold after a flood. Before entering a flooded area, make sure it is safe and free from electrical hazards or structural damage. Use protective gear: wear gloves, goggles, and a KN95/FFP2 mask to minimize exposure to mold spores. If there is still standing water, remove it as quickly as possible. Use pumps, wet-dry vacuums, or buckets to extract the water. Open windows and doors to facilitate air circulation and use fans, dehumidifiers, and HVAC systems to help dry the space. This step is crucial within the first 24-48 hours after flooding to prevent mold growth. Remove and discard any items that have been severely damaged by floodwater and cannot be thoroughly cleaned and dried. This includes carpets, upholstered furniture, mattresses, and any other porous materials. Thoroughly clean all hard surfaces with a detergent or cleaner suitable for mold remediation. Use a solution of 1.5 cups of bleach mixed with one gallon of water to disinfect nonporous surfaces. Never mix bleach with ammonia or other cleaning products, as the fumes are toxic. Maintain an indoor relative humidity (RH) of 35-50%. High humidity promotes mold growth, so consider using dehumidifiers in damp areas. Run a high-performance air purifier for mold, both during and after the mold removal work. If the flooding and mold damage are extensive, consider contacting professionals specializing in mold remediation to ensure proper cleanup and restoration.

Delhi and Kolkata ranked among the most polluted cities globally, as of 10:00 AM (IST), April 20, 2026, according to IQAir. When will the air quality improve in India? Short-term improvements depend on favorable weather; winds, rain, and increased atmospheric mixing will help disperse pollutants. In spring (March-May), as temperatures increase, hot air rises and cooler air sinks, easing pollution. However, early spring may still have stagnant air, low winds, and high temperatures trapping pollutants like PM2.5. Full relief comes with the monsoon season (June-September), which washes away pollutants and dramatically reduces PM2.5 levels, as seen in Kolkata where monsoon averages drop to 20-21 µg/m³ compared to winter highs of 77-80 µg/m³ (1).

Is the air quality good in India?

On April 20, 2026, air quality in India remains poor, with some of the major cities experiencing air quality in the \"unhealthy\" to \"very unhealthy\" range and high PM2.5 concentrations, posing serious health risks to residents, especially children and the elderly.

By 10:00 AM IST (Indian Standard Time, GMT+5:30), several urban centers have recorded AQI readings between 100 and 300, prompting health warnings. Residents are advised to limit outdoor activity, keep windows closed, wear masks when outside, and use air purifiers indoors.

While conditions remain poor, India’s average PM2.5 concentration in 2025 was 48.9 µg/m3, equivalent to an AQI of 134, classified as \"unhealthy for sensitive groups\". This level is nearly 9.78 times higher than the WHO annual guideline of 5 µg/m3, placing India sixth globally in the 2025 World Air Quality Report.

Which cities are affected by bad air quality in India?

On April 20, 2026, several major cities across India are reporting poor air quality. Some of the affected cities include:

Agra
Asansol
Delhi

Kolkata

Air quality conditions can change rapidly throughout the day. For a complete, real-time overview of pollution levels nationwide, see India's air quality map.

$\"\"$ Delhi and Kolkata ranked among the most polluted cities globally, as of 10:00 AM (IST), April 20, 2026, according to IQAir.

When will the air quality improve in India?

Short-term improvements depend on favorable weather; winds, rain, and increased atmospheric mixing will help disperse pollutants. In spring (March-May), as temperatures increase, hot air rises and cooler air sinks, easing pollution. However, early spring may still have stagnant air, low winds, and high temperatures trapping pollutants like PM2.5.

Full relief comes with the monsoon season (June-September), which washes away pollutants and dramatically reduces PM2.5 levels, as seen in Kolkata where monsoon averages drop to 20-21 µg/m³ compared to winter highs of 77-80 µg/m³ (1). Lasting improvement requires policy action and seasonal controls. Without those, severe episodes are likely to recur (2).

Clean the air with high-performance air filtration Learn more about our wildfire smoke air purifiers Click here Wildfire smoke and at-risk populations Most healthy adults will recover from smoke exposure. However, certain individuals are more at risk for severe health consequences, including:2 Young children. Children whose lungs are still developing are considered more vulnerable, regardless of whether they have a pre-existing condition. Pregnant women. Wildfire smoke inhalation puts pregnant women and their unborn children at a higher risk than the general population. Older adults. This population is at-risk due to an increased rate of pre-existing heart and lung disease. Anyone with a respiratory disease. Individuals with emphysema, chronic bronchitis, COPD, asthma, or another respiratory disease are at-risk. Individuals with heart disease. Circulatory diseases include high blood pressure, vascular diseases, heart failure, and cerebrovascular conditions. These conditions make sufferers susceptible to heart attacks, transient chest pain, heart failure, stroke, and sudden death from cardiac arrhythmia. Young children, pregnant women, older adults, and people with respiratory and cardiovascular pre-existing conditions may find that they experience more severe symptoms and find it harder to breathe.3 The full impact of wildfire smoke is not yet fully understood. A 2017 review in Environmental Toxicology and Pharmacology found that there are still important study opportunities for exploring the long-term health implications of smoke exposure, smoke exposure recovery, and additional smoke inhalation health impacts for children.4 Exposure to smoke can be dangerous simply due to the microorganisms within the smoke. A 2020 study in Science magazine noted that microorganisms, such as bacteria and fungal spores, comprise some of the particulate matter found in smoke.5 The study theorizes that infectious disease may be spread as bacteria and fungi become part of smoke’s particulate composition. Microorganisms, such as bacteria and fungal spores, comprise some of the particulate matter found in smoke, and infectious disease may be spread as they become part of the smoke’s particulate composition. How wildfire smoke behaves Many factors affect wildfire smoke behavior, such as: weather geographical terrain the stage of the fire wind Use the live, interactive air quality map below to see how weather, wind, and location can impact the behavior of wildfire smoke near you. Windy conditions generally cause smoke to mix with larger volumes of air to lower smoke concentrations. However, strong winds also can spread fires more quickly, causing larger fires with greater impact. Regional weather can be the dominant determinant in how a fire behaves as well as how smoke affects surrounding areas. However, regional weather systems can spread fires quickly and result in larger fires with more smoke generated, creating the potential for even greater impacts. Strong regional weather systems can also dominate a fire’s behavior for days and be the determining factor of where and how smoke will affect an area. Smoke can travel for miles beyond its source. In 2020, smoke from wildfires in the Western United States drifted for nearly 5,000 miles, eventually being detected in Europe. Smoke can travel for miles beyond its source. 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.","

The primary pollutant threatening the health of those nearby and downwind of a wildfire is particulate matter. Wildfire smoke often contains fine (or PM2.5) and ultrafine particles. These tiny airborne particles are the most dangerous to your health.

Fine particles (smaller than 2.5 microns) penetrate deeply into your lungs.

The most dangerous are ultrafine particles (smaller than 0.1 microns), which represent 90% of all airborne particles. These particles are tiny and can be absorbed directly into your bloodstream. Once in your blood, they can reach any organ or area of your body.

Wildfire smoke and at-risk populations

Most healthy adults will recover from smoke exposure. However, certain individuals are more at risk for severe health consequences, including:²

\n
Young children. Children whose lungs are still developing are considered more vulnerable, regardless of whether they have a pre-existing condition.
\n
\n
Pregnant women. Wildfire smoke inhalation puts pregnant women and their unborn children at a higher risk than the general population.
\n
\n
Older adults. This population is at-risk due to an increased rate of pre-existing heart and lung disease.
\n
\n
Anyone with a respiratory disease. Individuals with emphysema, chronic bronchitis, COPD, asthma, or another respiratory disease are at-risk.
\n
\n
Individuals with heart disease. Circulatory diseases include high blood pressure, vascular diseases, heart failure, and cerebrovascular conditions. These conditions make sufferers susceptible to heart attacks, transient chest pain, heart failure, stroke, and sudden death from cardiac arrhythmia.
\n

Young children, pregnant women, older adults, and people with respiratory and cardiovascular pre-existing conditions may find that they experience more severe symptoms and find it harder to breathe.³

The full impact of wildfire smoke is not yet fully understood. A 2017 review in Environmental Toxicology and Pharmacology found that there are still important study opportunities for exploring the long-term health implications of smoke exposure, smoke exposure recovery, and additional smoke inhalation health impacts for children.⁴

Exposure to smoke can be dangerous simply due to the microorganisms within the smoke. A 2020 study in Science magazine noted that microorganisms, such as bacteria and fungal spores, comprise some of the particulate matter found in smoke.⁵ The study theorizes that infectious disease may be spread as bacteria and fungi become part of smoke’s particulate composition.

How wildfire smoke behaves

Many factors affect wildfire smoke behavior, such as:

\n
weather
\n
\n
geographical terrain
\n
\n
the stage of the fire
\n
\n
wind
\n

Use the live, interactive air quality map below to see how weather, wind, and location can impact the behavior of wildfire smoke near you.

$\"placeholder$

Windy conditions generally cause smoke to mix with larger volumes of air to lower smoke concentrations. However, strong winds also can spread fires more quickly, causing larger fires with greater impact.

Regional weather can be the dominant determinant in how a fire behaves as well as how smoke affects surrounding areas. However, regional weather systems can spread fires quickly and result in larger fires with more smoke generated, creating the potential for even greater impacts.

Strong regional weather systems can also dominate a fire’s behavior for days and be the determining factor of where and how smoke will affect an area.

Smoke can travel for miles beyond its source. In 2020, smoke from wildfires in the Western United States drifted for nearly 5,000 miles, eventually being detected in Europe.

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.

\n
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.
\n
\n
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.
\n
\n
Wear a mask outdoors. Only use an air pollution mask with an N95, KN95, N100, or FFP2 rating to help.
\n
\n
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.
\n
\n
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.
\n
\n
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.

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.

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.

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.

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.

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

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.

Are scented candles bad for you?

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

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

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

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

Paraffin wax

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

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

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

alkenes
acetone
benzene
toluene

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

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

Is burning candles bad for you?

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

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

Ultrafine particles are associated with severe health issues, including:

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

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

Chemical fragrances

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

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

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

formaldehyde
petroleum distillates
limonene
alcohol
esters

These harmful chemicals can cause health problems, such as:

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

Cored wicks

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

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

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

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

Safer alternatives

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

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

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

The takeaway

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

","“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.

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.

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.\"

\nHighlighting areas of concern: Brikama’s air quality\n

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.
