How to find the best air purifier

The key to the best air quality is finding a purifier with a True HEPA filter. These filters can "remove at least 99.97% of dust, pollen, mold, bacteria and any airborne particles with a size of 0.3 microns," according to the Environmental Protection Agency (EPA) . For comparison, standard HEPA filters remove 99% of particles as small as two microns.
