We understand the myth of air purifiers and reveal the science behind how effective these appliances really are. Insisting on cleaning the air in our homes, air purifiers have long been among consumers who want to reduce exposure to air pollutants commonly found in home environments such as dust and pollen. It was popular for a while.
The importance of maintaining good indoor air quality has become a global news headline in recent months, along with people trying to eliminate the risk of COVID-19 aerosols entering their homes. And it’s not just the pandemics behind the current popularity of air purifiers, but many people due to wildfires on several continents and increasing levels of traffic pollution in major cities around the world. Have begun to look for ways to reduce exposure to smoke particles, carbon and other pollutants.
However, buying an air purifier is not a one-size-fits-all solution. We investigate some of the manufacturers’ claims and explore the truth behind the promise. Uncovering the myths of these common air purifiers will give you a better understanding of how these appliances can help you and your family.
Types of air purifiers
Before getting into the myths surrounding air purifiers, it is worth establishing the different types of features available in air purifiers.
HEPA filter: An air purifier with a HEPA filter removes more particles from the air than an air purifier without a HEPA filter. However, please note that terms such as HEPA type and HEPA style are not guaranteed to comply with industry regulations.
Carbon filter: Air purifiers with carbon filters also capture gases and volatile organic compounds (VOCs) emitted by common household cleaning products and paints.
sensor: An air purifier with an air quality sensor works when it detects contaminants in the air and often provides information about the air quality of the room in which it is located. In addition, a smart air purifier (connected to the internet) sends detailed reports directly to your smartphone, making it easy to monitor the air quality in your room.

Air Purifier Myth: They Improve Your Health
Air purifiers work by filtering polluted particles from the air.This is asthma Allergic patients may benefit from using one..according to British Lung FoundationIf pet allergies have been identified, you can use an air purifier to reduce pet allergens in the air. In such cases, we recommend a purifier equipped with a high-efficiency particulate air filter (HEPA filter).
However, it is only effective in controlling the cause and reducing symptoms if the allergen that causes the reaction can be captured. Also, as Dr. John O. Warner OBE (Professor Emeritus, National Institute of Cardiopulmonary Research, Imperial University of London) told Live Science, house dust mites and pet fluff cannot be captured when embedded in furniture or carpets.
Therefore, the claim that an air purifier improves your health is not technically a myth, but it really depends on finding a system that works for the individual. It’s also important to make sure your air purifier is ozone-free before you buy, as some emit low levels of ozone that can actually exacerbate the symptoms of asthma. Asthma UK.. As always, it is important to seek medical advice if you are experiencing a health problem or are uncertain about the best way to manage a diagnosed condition.
Air Purifier Myth: If you have an air conditioner, you don’t need an air purifier
Simply put, this statement is simply not true, so we can guarantee that the myth of this air purifier will be revealed soon. Air conditioning systems often have basic filtration capabilities, but they cannot filter the fine particles that HEPA filters can capture. The main function of an air conditioner is to regulate the temperature inside the room and is not designed to trap air pollutants. However, it is possible to achieve both of these goals by using an air conditioner and an air purifier at the same time.
Air Purifier Myth: A HEPA filter is required for an air purifier to work
Most air purifiers consist of one or more filters and a fan that draws in and circulates air. As the air passes through the filter, the particles are trapped and clean air is pushed back into the living space.
Air purifiers remove some particles from the air, but are fitted with HEPA filters (most often composed of multiple layers of net or mesh made of woven fiberglass or synthetic material. Can remove more particles). air. “The HEPA filter filters particles up to 0.3 microns, which is 99.9% of all particles up to 0.3 microns, including pollen grains, house dust mites and pet allergens, all of which are slightly larger.” I am. Dr. Warner. “But air purifiers only filter these particles in the zones created by the system, and in most purifiers, the zones are almost non-existent.”
Air Purifier Myth: Air Purifier Protects You from COVID-19
The ability of air purifiers to combat the diffusion of COVID-19 particles has been widely debated in recent months, and a £ 1.8 million study supported by the Ministry of Health is now effective in 30 primary schools in the United Kingdom. It is done to evaluate. Of an air purification system that removes viruses.
So is this the myth of an air purifier that needs to be uncovered? “The virus is below the limit set by the HEPA filter. However, because the virus is usually contained in the aerosol, the air filter may be able to trap the virus where the aerosol evaporates. However, most process viruses of about 0.3 micron. “
Until more definitive scientific evidence is published, Dr. Warner recommends that ensuring that the indoor space is well ventilated is the best approach. “Opening doors and windows to remove particles with an air stream is often better than using an air purifier,” he said.
