Utilizing close-by wildfires as an example, Dr. Roten includes 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 the majority of all the big particles that would be concerning,” he states. “The majority of the smoky smell will also be attended to as well.”
