What are air purifiers supposed to filter out and do they actually do it?

Most filters on the market are developed to catch particles like dust and pollen, however don’t catch gases like VOCs (unpredictable natural compounds) or radon. That would require an adsorbent, like triggered carbon. The Environmental Security Agency (EPA) cautions that the performance of air cleansers is limited in terms of filtering out gases, and that you must regularly change filters for optimal performance, typically about every 3 or so months.

Many air purifiers are proficient at filtering toxin particles out of the air (dust, smoke, pollen, etc.), however they are not always great at getting rid of gaseous toxins like VOCs or radon from the air that might collect from adhesives, paints, or cleansing items. Allergens that are embedded into furniture or floor covering are also not captured by them.

Furthermore, the effectiveness of air purifiers in real-world situations likely won’t simulate those of controlled conditions in a laboratory (what those “99% efficiency” claims are describing!). The place, installation, flow rate, and for how long it is running for will all vary, as will the conditions in the area. In addition, there are other things taking place in your home that might effect the effectiveness like ventilation (open or closed windows), and brand-new particles are continuously emerging, so the air might not as filtered as the claims might have you believe.

Using 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 sufficient enough to filter out the majority of all the large particles that would be concerning,” he states. “The majority of the smoky odor will likewise be dealt with as well.”

What should I try to find in an air cleanser?

CADR (clean-air shipment rate) ranking. This determines the cleaning speed of the cleanser for removing smoke, dust, and and pollen. Search for a CADR of a minimum of 300, above 350 is actually terrific.

For correct efficacy, you need a design developed to work in the space size. Pick a design that is developed for a location larger than the one you are equipping it for if you wish to operate it at a lower, quieter setting.

True HEPA. Real HEPA filters work at eliminating ultra fine particles (think: dust, dander, pollen, mold and other common allergens in the house). The industry requirement for such is that the system needs to be able to get rid of at least 99.97% of particulates measuring 0.3 micron size in a lab setting. Remember, it is very important to note that in real life settings, the real efficacy of these gadgets would be far less as new contaminants are constantly emerging. Note that there is no industry requirement for the terms “HEPA-like” or “HEPA-type,” and are primarily used as marketing tactics to get customers to buy the product.
