The Elite Allergen Air Filter is made of a reinforced pleated media designed to capture particles down to the micro particle level. The large surface area improves the efficiency of its dust-holding capacity. Its electrostatic charge helps attract particles "magnetically" that otherwise would pass through. Housed in a recyclable clay-coated frame, this filter captures particles as small as 0.3 microns. In comparison, a human hair is approximately 100 microns in size. The Elite Allergen is effective against the following contaminants: dust/lint, airborne dust mite debris, pollen, pet dander, mold spores, bacteria, microscopic allergens, virus carriers and odor, most smoke and smog particles.
