Dust is not the only menace floating around in the air. Particles such as mold, pollen and pet dander can be equally as irritating. In an effort to keep our customers informed, Air Purifiers America conducted tests on several models of air purifiers using a specialty laser particle counter to measure the percentage of particles removed from the air. The device was able to count particles such as pollen, dust, mold and pet dander as small as 0.3 microns. The resulting information follows, with higher percentage numbers indicating more particles removed from the air by the corresponding air cleaner.
