Do Air Purifiers Really Work?

Experts weighs in on whether purifiers can truly filter out germs, dust, smoke, mold, and more.

How do air purifiers work?

Air cleansers typically consist of a filter, or multiple filters, and a fan that absorbs and flows air.

As air moves through the filter, contaminants and particles are captured and the tidy air is pushed back out into the home. Usually, filters are made from paper, fiber (frequently fiberglass), or mesh, and need routine replacement to keep effectiveness.

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

The majority of filters on the market are developed to record particles like dust and pollen, however don’t capture gases like VOCs (volatile organic compounds) or radon. That would need an adsorbent, like triggered carbon. In fact, the Epa (EPA) cautions that the performance of air cleansers is limited in regards to filtering out gases, and that you must regularly replace filters for optimal performance, usually about every three or two months.

Allergens that are embedded into furniture or floor covering are also not recorded by them.

Furthermore, the effectiveness of air cleansers in real-world situations likely won’t mimic those of controlled conditions in a lab (what those “99% efficiency” claims are referring to!). The area, installation, circulation rate, and the length of time it is operating 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.

What should I try to find in an air purifier?

CADR (clean-air shipment rate) ranking. This determines the cleansing speed of the cleanser for getting rid of smoke, dust, and and pollen. Look for a CADR of at least 300, above 350 is really great.

The requirements are designed to provide a common understanding in between manufacturers and consumers to help make the buying process easier.

Real HEPA. True HEPA filters work at eliminating ultra fine particles (think: dust, dander, pollen, mold and other typical irritants in the home). The industry standard for such is that the system needs to be able to eliminate at least 99.97% of particulates determining 0.3 micron size in a laboratory setting. Remember, it is very important to note that in reality settings, the actual effectiveness of these gadgets would be far less as brand-new toxins are constantly emerging. Note that there is no market standard for the terms “HEPA-like” or “HEPA-type,” and are mostly used as marketing ploys to get consumers to purchase the item.
