Using nearby 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 adequate enough to filter out the majority of all the big particles that would be concerning,” he states. “Most of the smoky smell will also be resolved also.”

What should I search for in an air cleanser?

CADR (clean-air delivery rate) ranking. This measures the cleaning 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 great.
