Do Air Purifiers Really Work?

Professionals weighs in on whether or not cleansers can truly filter out bacteria, dust, smoke, mold, and more.

Allergens that are embedded into furniture or flooring are also not caught by them.

Additionally, the effectiveness of air cleansers in real-world circumstances likely won’t simulate those of regulated conditions in a lab (what those “99% effectiveness” claims are describing!). The place, installation, circulation rate, and how long it is operating for will all vary, as will the conditions in the area.

Keep in mind, it is very important to note that in real life settings, the actual efficacy of these gadgets would be far less as new toxins are continuously emerging.
