This 6-in-1 Air Purifier Console with HEPA filter helps to relieve allergies by capturing 99.97% of dust and allergens as small as .3 microns in size. The activated carbon filter attacks common household odors including those caused by smoke, cooking, and pets. The UV-C light helps reduce airborne bacteria, viruses, mold spores* and reduces volatile organic compounds. Features touch controls, 4 fan speeds, an air quality monitor, auto mode, UV-C, ionizer, sleep mode, 8-hour timer, and a child lock. The Air Quality Monitor detects the number of particles in the air and displays the air rating on a 3 color LED display. Auto Mode reads real time air quality and automatically adjusts the fan speed, providing you with peace of mind that your unit is filtering your air accordingly. The built-in ionizer option can be used to boost allergen control. The ionizer emits negative ions that attract microscopic allergens to form larger particles that can be easily trapped by the HEPA filter. Sleep mode runs the unit on library quiet low speed and turns the display lights off. This GermGuardian air purifier stands about 23 and is ideal for use in rooms up to 394 sq. feet.
