About indoor air pollution The Centers for Disease Control and Prevention (CDC)Trusted Source states that low outdoor air quality can be detrimental to health. The organization also says that many people experience exposure to smog and particle pollution. However, research has shown that many people are not aware that indoor air quality may be worse than outdoor air quality. One of the harmful pollutants that individuals can find indoors is dust. It comes from dead skin cells, stray particulates, and dust mites, which are major triggers for people with allergies and asthma, according to the American Lung Association. In addition, one article Trusted Source found that house dust and its components also have associations with respiratory infections, wheezing, and respiratory allergic diseases.

Do air purifiers work? The EPA acknowledges that air purifiers cannot remove all the air pollutants in a person’s home, but they can improve air quality. Most air purifiers can remove particles from the air, and some can remove both particles and gases. Using air purifiers with an activated carbon filter, a longer running time, and that are the right size for the room where they will operate will yield the best results. Removing sources of indoor air pollution, such as tobacco, and ventilating the area with fresh air will also improve air quality.

Benefits of using air purifiers for dust People can improve their indoor air quality by reducing sources of contamination, such as smoking. However, it is impossible to remove all harmful particles from the air. A 2020 article states that walking around and sitting on furniture can lead to 25%Trusted Source of indoor particulate matter concentrations. Using air purifiers to remove dust can reduce concentrations of small particles by 30–80%, which offers some of the following health benefits:

  • fewer nighttime symptoms, especially in people with asthma

  • reducing the risk of cardiovascular disease

  • improving sleep quality

  • removing hazardous asbestos particles


Risks of using an air filter Some air purifiers produce ozone, which irritates the lungs. The EPA recommends avoiding these products. Some air purifiers that rely on bipolar ionization technology may produce ozone, but not all of them. If using a device based on bipolar ionization technology, people should look for ones that meet UL 2998 standard certification because these will not produce ozone. To be as effective and safe as possible, all air purifiers need cleaning and new filters (as appropriate) on a regular basis.

What to look for When it comes to using air purifiers for dust removal, people should consider the filters they use. According to the Environmental Protection Agency (EPA), devices with a high-efficiency particulate air (HEPA) filter can remove 99.97% of airborne particles with a size of 0.3 microns. These include dust, pollen, mold, and bacteria. Learn more about HEPA air purifiers.

How to choose There are some features to consider when choosing an air purifier for dust:

  • Clean Air Delivery Rate (CADR): Refers to the volume of particles the unit can filter in a set time, and it should match the size of the room where a person will use it.

  • Target use: Some air purifiers work on removing particles, while others focus on gases. People looking for air purifiers for dust control should look for filters that target dust removal specifically.

  • Filters: Some devices feature more than one filter, so a person should check when they should replace them.

  • Fan speed: There are devices featuring fans that adjust their speeds according to the pollutant levels. Their speed also lowers during the night, so the unit does not disturb sleeping people.
