In addition, the efficiency of air cleansers in real-world circumstances most likely will not simulate those of regulated conditions in a lab (what those “99% effectiveness” claims are describing!). The area, installation, circulation rate, and the length of time it is running for will all vary, as will the conditions in the space.

What should I try to find in an air cleanser?

CADR (clean-air shipment rate) ranking. This measures the cleaning speed of the cleanser for getting rid of smoke, dust, and and pollen. Try to find a CADR of at least 300, above 350 is really excellent.

For correct effectiveness, you need a design developed to work in the room size. Pick a model that is designed for an area larger than the one you are outfitting it for if you wish to operate it at a lower, quieter setting.

Remember, it is very important to note that in reality settings, the actual efficacy of these devices would be far less as new contaminants are constantly emerging.
