The Hospital Quality Air Filter

With long-lasting filters and a swift cleaning system, this air cleaner is based on the technology of a hospital "clean room." Developed by a husband-and-wife team who could only find relief for her breathing troubles in a "clean room," this unit uses three filters: a HEPA filter for sub-micron particles, a carbon Zeolite mix for more than 3,000 toxic gases and odors, and a thick pre-filter for larger particulate like dust and dander. The filter lasts as long as five years without needing to be changed. It can reduce a room"s harmful airborne matter in 15 minutes--but for allergy or asthma sufferers who need cleaner air faster, this unit delivers a "pocket" of filtered air to a zone above its output vent in 15 seconds. Plugs into AC. Black or White. 23 1/2" H x 13" W x 13" D. (45 lbs.)
