Do Air Purifiers Really Work?

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

How do air cleansers work?

Air cleansers normally include a filter, or multiple filters, and a fan that sucks in and distributes air.

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

Many filters on the marketplace are designed to catch particles like dust and pollen, but don’t capture gases like VOCs (volatile organic substances) or radon. That would need an adsorbent, like activated carbon. In fact, the Epa (EPA) cautions that the functionality of air cleansers is restricted in terms of filtering out gases, which you must regularly replace filters for optimal functionality, typically about every three approximately months.

Lots of air purifiers are good at filtering toxin particles out of the air (dust, smoke, pollen, etc.), but they are not always excellent at getting rid of gaseous pollutants like VOCs or radon from the air that may build up from adhesives, paints, or cleaning items. Irritants that are embedded into furnishings or floor covering are also not captured by them.

Furthermore, the efficiency of air purifiers in real-world circumstances likely won’t simulate those of controlled conditions in a laboratory (what those “99% efficiency” claims are referring to!). The area, setup, flow rate, and the length of time it is running for will all differ, as will the conditions in the area. In addition, there are other things taking place in your house that may effect the efficacy like ventilation (open or closed windows), and new particles are continuously emerging, so the air might not as filtered as the claims may have you believe.

If you are concerned about mold, we ‘d suggest purchasing a dehumidifier or humidifier to help keep the proper moisture levels in your home and stave off mold growth problems. Air cleansers do not avoid mold growth, so it is needed to get rid of the source of wetness that is allowing it to grow.

Using neighboring wildfires as an example, Dr. Roten includes that a HEPA filter-equipped purifier is your best option: “Anything that has a true HEPA filter in it is most likely adequate sufficient to filter out many all the big particles that would be worrying,” he states. “The majority of the smoky odor will also be resolved also.”

The industry standard for such is that the unit should be able to remove a minimum of 99.97% of particulates determining 0.3 micron size in a lab setting. Remember, it is very important to keep in mind that in reality settings, the real efficacy of these devices would be far less as new contaminants are continuously emerging.
