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

Most filters on the marketplace are developed to capture particles like dust and pollen, but do not capture gases like VOCs (unpredictable natural substances) or radon. That would need an adsorbent, like activated carbon. In fact, the Epa (EPA) alerts that the functionality of air purifiers is limited in terms of filtering out gases, which you should frequently replace filters for optimum functionality, typically about every three approximately months.

Many air purifiers are proficient at filtering pollutant particles out of the air (dust, smoke, pollen, etc.), however they are not necessarily great at getting rid of gaseous pollutants like VOCs or radon from the air that may build up from adhesives, paints, or cleaning items. Allergens that are embedded into furnishings or floor covering are also not recorded by them.

Additionally, the efficiency of air purifiers in real-world situations likely will not imitate those of controlled conditions in a lab (what those “99% effectiveness” claims are referring to!).

Real HEPA. Real HEPA filters are effective at removing ultra fine particles (think: dust, dander, pollen, mold and other common irritants in the home). The industry standard for such is that the system needs to have the ability to eliminate at least 99.97% of particulates measuring 0.3 micron size in a laboratory setting. Remember, it is important to note that in reality settings, the actual effectiveness of these gadgets would be far less as new toxins are continuously emerging. Keep in mind that there is no industry requirement for the terms “HEPA-like” or “HEPA-type,” and are primarily used as marketing ploys to get consumers to purchase the product.
