What are air cleansers supposed to filter out and do they really do it?

A lot of filters on the marketplace are designed to catch particles like dust and pollen, but do not catch gases like VOCs (unstable natural substances) or radon. That would require an adsorbent, like activated carbon. The Environmental Defense Firm (EPA) warns that the performance of air purifiers is restricted in terms of filtering out gases, and that you must frequently change filters for optimal functionality, usually about every 3 or so months.

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 will not simulate those of regulated conditions in a lab (what those “99% efficiency” claims are describing!). The area, installation, circulation rate, and how long it is operating for will all differ, as will the conditions in the area. In addition, there are other things happening in your home that may effect the effectiveness like ventilation (open or closed windows), and brand-new particles are constantly emerging, so the air may not as filtered as the claims might have you believe.

What should I try to find in an air cleanser?

CADR (clean-air delivery 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 truly great.

Real HEPA. True HEPA filters work at eliminating ultra fine particles (think: dust, dander, pollen, mold and other typical allergens in the house). The industry standard for such is that the system needs to have the ability to get rid of a minimum of 99.97% of particulates measuring 0.3 micron size in a lab setting. Keep in mind, it is essential to keep in mind that in real life settings, the real effectiveness of these gadgets would be far less as brand-new toxins are continuously emerging. Note that there is no market standard for the terms “HEPA-like” or “HEPA-type,” and are mainly used as marketing ploys to get customers to purchase the item.

    In addition, the efficiency of air cleansers in real-world circumstances likely will not mimic those of controlled conditions in a laboratory (what those “99% efficiency” claims are referring to!).
