The 5-in-1 Air Purifier is perfect for allergy sufferers. The HEPA Filter captures 99.97% of allergens including pet dander, dust mites and pollen. The 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, 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, and Escherichia Coli, Aspergillus Niger, and Phi-X174
