What should I look for in an air purifier?

CADR (clean-air delivery rate) score. This measures the cleaning speed of the cleanser for getting rid of smoke, dust, and and pollen. Look for a CADR of a minimum of 300, above 350 is really excellent.

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

The industry standard for such is that the unit should have the ability to eliminate a minimum of 99.97% of particulates determining 0.3 micron size in a laboratory setting. Keep in mind, it is essential to keep in mind that in reality settings, the actual effectiveness of these gadgets would be far less as new contaminants are constantly emerging.
