Do Air Purifiers Actually Work?

Professionals weighs in on whether or not cleansers can truly filter out germs, dust, smoke, mold, and more.

Allergens that are embedded into furniture or floor covering are likewise not recorded by them.

Additionally, the effectiveness of air cleansers in real-world scenarios likely will not mimic those of regulated conditions in a laboratory (what those “99% effectiveness” claims are describing!). The area, installation, flow rate, and the length of time it is running for will all vary, as will the conditions in the space.

Using neighboring wildfires as an example, Dr. Roten includes that a HEPA filter-equipped cleanser is your best bet: “Anything that has a real HEPA filter in it is most likely appropriate sufficient to filter out many all the big particles that would be concerning,” he states. “The majority of the smoky smell will also be addressed as well.”

What should I search for in an air purifier?

CADR (clean-air delivery rate) score. This determines the cleansing speed of the cleanser for removing smoke, dust, and and pollen. Look for a CADR of a minimum of 300, above 350 is actually great.

For correct efficacy, you need a model developed to work in the room size. Choose a model that is developed for an area larger than the one you are outfitting it for if you want to operate it at a lower, quieter setting.
