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

The majority of filters on the marketplace are designed to catch particles like dust and pollen, but do not capture gases like VOCs (unstable organic substances) or radon. That would require an adsorbent, like triggered carbon. In fact, the Environmental Protection Agency (EPA) alerts that the performance of air purifiers is restricted in terms of filtering out gases, which you need to frequently replace filters for ideal performance, normally about every 3 approximately months.

Many air cleansers are good at filtering contaminant particles out of the air (dust, smoke, pollen, and so on), but they are not always very good at getting rid of gaseous contaminants like VOCs or radon from the air that may accumulate from adhesives, paints, or cleaning items. Irritants that are embedded into furnishings or floor covering are also not caught by them.

Additionally, the effectiveness of air cleansers in real-world scenarios likely will not simulate those of regulated conditions in a laboratory (what those “99% effectiveness” claims are describing!). The area, installation, circulation rate, and how long it is running for will all differ, as will the conditions in the space.

True HEPA. Real HEPA filters work at removing ultra fine particles (think: dust, dander, pollen, mold and other common irritants in the house). The market requirement for such is that the system should be able to eliminate a minimum of 99.97% of particulates measuring 0.3 micron size in a lab setting. Keep in mind, it is important to note that in reality settings, the actual efficacy of these devices would be far less as new pollutants are constantly emerging.
