Honeywell Honeywell AC & Heating Filters 17-1/2 in. x 20 in. x 1 in. Superior Allergen Pleated FPR 9 Air Filter 90901I0117520
The Honeywell Superior Allergen is made of a reinforced pleated media with a large surface area which improves the efficiency of its dust-holding capacity. The unique construction of Honeywell Superior Allergen filters requires less energy for lower energy cost. Its electrostatic charge helps attract particles â€œmagneticallyâ€? that otherwise would pass through. Housed in a recyclable clay-coated moisture resistant frame, this filter captures particles as small as 1 micron. In comparison, a human hair is approximately 100 microns in size. The Honeywell Superior Allergen is effective against the following contaminants: dust/lint, airborne dust mite debris, pollen, pet dander, mold spores, bacteria, microscopic allergens, virus carriers and most smoke.
