21x23x1 Exact MERV 7 Plus Carbon AC Furnace Filters 6 Pack BVV Design keeps them both containedNordic Pure pleated AC air filters are made of electrostatically charged synthetic materials that attract and capture most airborne particulates in your home or office. Each time air passes through a Nordic Pure pleated furnace filter, lint, household dust, pollen, dust mites, pet dander, baking flour, mold spores and other contaminants are removed. Our filter media prevents the growth of bacteria or mold, resulting in a much healthier living space.
