A lot of filters on the market are developed to record particles like dust and pollen, but don’t capture gases like VOCs (volatile natural compounds) or radon.

Many air purifiers are good at filtering contaminant particles out of the air (dust, smoke, pollen, etc.), but they are not always great at eliminating gaseous pollutants like VOCs or radon from the air that may build up from adhesives, paints, or cleansing products.

Additionally, the efficiency of air purifiers in real-world circumstances most likely will not imitate those of regulated conditions in a lab (what those “99% efficiency” claims are describing!). The place, setup, flow rate, and the length of time it is operating for will all vary, as will the conditions in the space.

Utilizing nearby wildfires as an example, Dr. Roten adds that a HEPA filter-equipped cleanser is your best choice: “Anything that has a true HEPA filter in it is most likely sufficient sufficient to filter out most all the big particles that would be concerning,” he says. “The majority of the smoky smell will also be addressed too.”

What should I try to find in an air cleanser?

CADR (clean-air delivery rate) score. This measures the cleansing speed of the cleanser for getting rid of smoke, dust, and and pollen. Try to find a CADR of a minimum of 300, above 350 is truly excellent.

For proper effectiveness, you need a model designed to work in the room size. Select a model that is created for an area larger than the one you are outfitting it for if you want to run it at a lower, quieter setting.
