Utilizing neighboring wildfires as an example, Dr. Roten adds that a HEPA filter-equipped purifier is your best bet: “Anything that has a real HEPA filter in it is most likely sufficient enough to filter out most all the big particles that would be worrying,” he says. “The majority of the smoky odor will likewise be resolved as well.”

What should I try to find in an air purifier?

CADR (clean-air delivery rate) score. This determines the cleaning speed of the purifier for getting rid of smoke, dust, and and pollen. Look for a CADR of a minimum of 300, above 350 is actually fantastic.

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