What the experts say
“Portable air cleaners have the potential to improve indoor air quality for any person who uses them properly. The longer the air cleaner runs, the more air it filters.” Tim Carroll, Environmental Protection Agency
One important feature to look out for when shopping for air purifiers for allergies is a high-efficiency particulate absorbing (HEPA) filter, which uses very small fiberglass threads to capture extremely small particles in the air and trap pollutants. According to a report from the Environmental Protection Agency, this type of filter can “theoretically remove at least 99.97% of dust, pollen, mold, bacteria and airborne particles with a size of 0.3 microns”. When it comes to choosing the perfect air purifier for you, Tim Carroll, a representative from the Environmental Protection Agency told Live Science:
“Choosing the right air cleaner will depend on the type of pollutant the user is targeting. In general, to filter particles, choose a portable air cleaner that has a clean air delivery rate (CADR) that is large enough for the size of the room or area in which you will use it.”
