Research has shown the primary cause of allergies is due to high levels of dust, pollen or mold particles. Allergy symptoms can be greatly reduced when these particles are removed from the air with air purifiers .

We tested manufacturers’ models at our offices with a high-end particle count to measure the amount of particles 0.3 microns and larger that each unit could remove from the air. This represents all pollen, mold spores, pet dander and most of the dust in a home. To view test results, see Independent test results in home environments
