Honeywell The Honeywell HEPA Air Purifier for Small Rooms is perfect for small rooms. Its stylish design and small footprint allow it to be placed either on a tabletop or the floor. The True HEPA filter effectively captures up to 99.97% of microscopic allergens as small as 0.3 microns.1 1 From the air that passes through the filter, 0.3 microns and larger. It also reduces odours, VOCs (volatile organic compounds), and certain germs.1,2 2 Based on independent testing report 100954017COL-001 How the air purifier works: a fan continuously draws in airborne pollutants. The dirty air passes through the activated carbon pre-filter that traps large particles and absorbs VOCs, gases and odours. The air then passes through the HEPA filter that captures the really small particles, such as dust, pollen, pet dander, smoke and more. The filtered, cleaner and fresher smelling air is then circulated back into the room. Honeywell Air Purifiers are the #1 brand recommended by Allergists.3 3 Based on the Nov. 2014 Cascade Survey Research results reporting 80 out of 84 (95%) surveyed Allergists that recommend a brand of portable air purifiers to their patients, recommend “Honeywell” air purifiers.
