Lots of air purifiers are proficient at filtering pollutant particles out of the air (dust, smoke, pollen, etc.), however they are not always very good at removing gaseous pollutants like VOCs or radon from the air that may collect from adhesives, paints, or cleansing items. Allergens that are embedded into furnishings or flooring are likewise not recorded by them.

In addition, the effectiveness of air cleansers in real-world scenarios most likely will not mimic those of regulated conditions in a laboratory (what those “99% effectiveness” claims are describing!). The place, setup, flow rate, and the length of time it is running for will all vary, as will the conditions in the area.

Using nearby wildfires as an example, Dr. Roten includes that a HEPA filter-equipped cleanser is your best option: “Anything that has a real HEPA filter in it is probably sufficient enough to filter out a lot of all the large particles that would be concerning,” he says. “Most of the smoky smell will also be attended to as well.”

What should I try to find in an air cleanser?

CADR (clean-air shipment rate) rating. This measures the cleansing speed of the purifier for removing smoke, dust, and and pollen. Look for a CADR of a minimum of 300, above 350 is actually great.

For proper effectiveness, you need a design developed to operate in the space size. Pick a model that is developed for a location larger than the one you are outfitting it for if you wish to operate it at a lower, quieter setting.

The market standard for such is that the system needs to be able to eliminate at least 99.97% of particulates measuring 0.3 micron diameter in a lab setting. Remember, it is essential to keep in mind that in real life settings, the real efficacy of these devices would be far less as new contaminants are constantly emerging. Keep in mind that there is no industry standard for the terms “HEPA-like” or “HEPA-type,” and are mainly utilized as marketing ploys to get customers to buy the product.
