What should I look for in an air cleanser?

CADR (clean-air shipment rate) score. This determines the cleaning speed of the cleanser for eliminating smoke, dust, and and pollen. Look for a CADR of at least 300, above 350 is really excellent.

For correct effectiveness, you need a design created to operate in the room size. Pick a design that is created for a location larger than the one you are equipping it for if you want to operate it at a lower, quieter setting.

Keep in mind, it is necessary to keep in mind that in reality settings, the actual effectiveness of these gadgets would be far less as new toxins are continuously emerging.
