Vornado AC500 True HEPA Air Purifier

The Vornado AC500 Whole Room Air Purifier uses true HEPA filtration, one of the most effective filters available, to remove up to 99.97% of airborne allergens down to .3 microns in size. The Vornado Whole Room Purifier actively circulates and filters all the air throughout a room. Without powerful circulation, the air cleaner is only cleaning the immediate area around the unit. The AC500 uses a radial blower to intake and clean all the air in a room - up to 335 sq. ft . Precision engineering allows the blower to operate quietly, despite it's powerful air flow. The AC500 uses a combination of 2 HEPA and 2 carbon filters to trap Dust, Pollen, Pet Dander, Smoke, Bacteria, Mold Spores, Dust Mites, and more. The carbon prefilter both adsorbs odors and traps larger particles. When in €˜auto mode€, advanced dust sensing technology detects the level of dust in a room, fluctuating the cleaning cycle up or down, depending on the air quality. Features 4 speeds, push button electronic controls, filter replacement indicator, sleep mode and industry leading 5 year limited warranty.
