What should I try to find in an air cleanser?

CADR (clean-air delivery rate) rating. This determines the cleansing speed of the purifier for getting rid of smoke, dust, and and pollen. Try to find a CADR of at least 300, above 350 is actually terrific.

For correct efficacy, you require a model designed to work in the space size. Select a model that is created for a location larger than the one you are equipping it for if you want to run it at a lower, quieter setting.

Remember, it is essential to keep in mind that in real life settings, the real efficacy of these devices would be far less as new contaminants are constantly emerging.
