This Honeywell InSight™ HEPA Air Purifier console helps provide cleaner, fresher air in Medium-Large rooms of 190 square feet. Featuring HEPA filtration, this air purifier has been engineered to help capture up to 99.97% of the following microscopic airborne allergens and particles: dust, pollen, pet dander, dust mite debris and smoke¹. The activated carbon pre-filter helps capture large airborne particles and reduces odors and VOCs. This model's effective design and filtration can circulate and clean the air an amazing 4.8 times per hour in a 190 square foot room². Additional optional enhanced odor & VOC filters can be purchased, to help tackle specific household odors and VOCs from pets, kitchens, smoke or home renovation. Disclaimers: ¹ From the air that passes through the filter, 0.3 microns and larger. ² Based on 3rd party independent CADR testing for the smoke CADR value when operated at the highest level. Air circulation depends on many factors, such as room size and configuration. There is no guarantee that all of the air in a room will pass through the filter.
