What is an air purifier and how does it work
How air purifiers function to capture indoor pollutants
Air purifiers are devices designed to improve indoor air quality by removing airborne particles, pollutants, and allergens from the air in your home. They work by drawing room air through a series of filters, each targeting different types of contaminants. The most common types of air filters include HEPA filters, activated carbon filters, and pre-filters. HEPA filters are especially effective at trapping fine particulate matter such as dust, pollen, pet dander, and even some bacteria. Activated carbon filters help absorb odors, smoke, and volatile organic compounds (VOCs), making the air feel fresher and cleaner.
- HEPA filters: Capture up to 99.97% of airborne particles as small as 0.3 microns, including dust mites and allergens.
- Activated carbon: Absorbs gases, odors, and chemical vapors, which can be especially helpful for households with smokers or pets.
- Pre-filters: Trap larger particles like hair and dust, extending the life of the main filters.
Some air cleaners also use additional technologies, such as UV-C light or ionizers, to neutralize bacteria and viruses. However, not all technologies are equally effective or safe. For example, ozone generators are sometimes marketed as air purifiers, but they can actually introduce harmful ozone into your indoor air, which may worsen respiratory issues (EPA).
Portable air purifiers are popular because they can be moved from room to room, providing targeted clean air where you need it most. The benefits air purifiers offer depend on the type of filter and the size of the room. For those interested in optimizing their air purifier's performance, using a humidistat controller can help maintain ideal humidity levels, which supports both filter efficiency and overall air quality.

While purifiers can capture many airborne particles like dust, pollen, pet dander, and smoke, they don’t eliminate every type of indoor air pollution right away. The effectiveness depends on the purifier’s filter type, the size of the room, and the concentration of pollutants. HEPA filters, for example, are highly efficient at trapping particulate matter, but gases and odors may require activated carbon filters.
- "All air purifiers are the same." Not all purifiers use the same technology. Some rely on HEPA filters for particles, others use activated carbon for odors, and some use UV or ionization. Each type targets different pollutants, so it’s important to match the purifier to your specific needs, such as allergies, asthma, or smoke sensitivity.
- "Air purifiers cure respiratory conditions." While air cleaners can help reduce exposure to allergens and airborne particles, they are not a cure for asthma or other respiratory issues. They can, however, support better respiratory health by lowering the amount of dust mites, pet dander, and other triggers in the air.
- "Ozone generators are safe for indoor use." Some devices marketed as air purifiers generate ozone, which can actually worsen indoor air quality and irritate the lungs. Most experts recommend avoiding ozone generators for home use, especially if you have children, pets, or anyone with respiratory conditions.
- "Air purifiers don’t need regular maintenance." To maintain clean air and the long term benefits air purifiers offer, filters must be replaced or cleaned as recommended by the manufacturer. Neglecting this can reduce the purifier’s effectiveness and may even release trapped pollutants back into the room.
Understanding these facts can help you make informed decisions about improving your indoor air quality and choosing the right air purifier for your needs. Remember, the right purifier can make a significant difference, but it’s not a magic solution for all indoor air problems.
