Envion 19 in. H X 6 in. W Rectangular HEPA Air Purifier Filter 1 pk 49294

This air purifier captures at least 99.97% of all allergens and irritants, down to 0.3 microns, that pass through the filter. Studies show that due to global warming and longer spring seasons, airborne pollen and dust have increased dramatically and will continue to increase. With that knowledge, consumer spending on allergy-related products has increased and dollars spent on drugs, shots, and homeopathic remedies are at an all-time high. Combining True HEPA filtration and unique and powerful engineering, Allergy Pro professional air purifiers make it easy and affordable to maintain an allergen-free environment. Allergy Pro professional air purifiers eliminate the major airborne causes of allergic and respiratory distress: particulate matter (pollen, dust and other allergens).
