The 5-in-1 Air Purifier is perfect for allergy sufferers. The HEPA Filter captures 99.97 percent of allergens including pet dander, dust mites, and pollen. Pet Pure is an antimicrobial agent added to the filter to inhibit the growth of mold, mildew, and odor-causing bacteria on the surface of the filter. More than just a filter, UV-C light helps reduce airborne bacteria, viruses, and mold spores and works with Titanium Dioxide to reduce volatile organic compounds. Standing 28 inches tall, it is lightweight and ideal to use in rooms up to 189 sq. feet. The easy-to-use digital display panel includes UV-C control, a filter change indicator, and an up to 8-hour timer. 5 speeds provide high-speed allergen control down to ultra-quiet sleep mode. Tested with Staphylococcus Albus, Escherichia Coli, Aspergillus Niger, and Phi-X174.
