Do Air Purifiers Actually Work?

Experts weighs in on whether or not cleansers can truly filter out germs, dust, smoke, mold, and more.

How do air purifiers work?

Air cleansers usually include a filter, or several filters, and a fan that sucks in and circulates air.



A lot of filters on the market are created to catch particles like dust and pollen, however don’t catch gases like VOCs (unpredictable organic compounds) or radon. That would require an adsorbent, like triggered carbon. The Environmental Security Firm (EPA) cautions that the performance of air cleansers is restricted in terms of filtering out gases, and that you must often change filters for ideal functionality, normally about every three or so months.

Many air purifiers are good at filtering toxin particles out of the air (dust, smoke, pollen, and so on), but they are not necessarily great at eliminating gaseous pollutants like VOCs or radon from the air that might collect from adhesives, paints, or cleaning items. Allergens that are embedded into furniture or flooring are likewise not captured by them.

Furthermore, the efficiency of air purifiers in real-world situations likely won’t simulate those of regulated conditions in a lab (what those “99% efficiency” claims are referring to!). The area, setup, flow rate, and the length of time it is running for will all differ, as will the conditions in the area. In addition, there are other things happening in your house that might effect the effectiveness like ventilation (open or closed windows), and new particles are constantly emerging, so the air might not as filtered as the claims may have you think.

But that would largely require to be someone who was standing straight in or near the fire: Those people are given emergency rooms right away,” Dr. Roten discusses. “Typically, outdoors contamination or smoke or short-lived bad air isn’t a continuous issue for bystanders.” But the ideal type of purifier can resolve any ecological air qualities in your place. Utilizing nearby wildfires as an example, Dr. Roten includes that a HEPA filter-equipped cleanser is your best bet: “Anything that has a real HEPA filter in it is probably appropriate sufficient to filter out many all the big particles that would be concerning,” he says. “Most of the smoky smell will also be addressed too.”
