What should I try to find in an air purifier?

CADR (clean-air delivery rate) rating. This measures the cleansing speed of the cleanser for eliminating smoke, dust, and and pollen. Look for a CADR of a minimum of 300, above 350 is really great.

For correct effectiveness, you require a design developed to work in the space size. Choose a design that is created for a location larger than the one you are outfitting it for if you want to run it at a lower, quieter setting.

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