Using nearby wildfires as an example, Dr. Roten adds that a HEPA filter-equipped cleanser is your best bet: “Anything that has a real HEPA filter in it is most likely appropriate enough to filter out the majority of 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 try to find in an air cleanser?

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 truly terrific.

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

Keep in mind, it is essential to keep in mind that in real life settings, the real efficacy of these devices would be far less as new pollutants are constantly emerging.
