DESC: This is the air purifier which uses heated air to destroy airborne mold, bacteria, viruses, dust mites, and pollens. Unlike commonly available ionic units, it does not produce harmfully elevated ozone levels; it also reduces existing indoor ozone, which the America Lung Association indicates can be a serious respiratory irritant and asthma trigger. With no filters to replace or clean, the compact cleaner pulls air into the internal chamber which is heated to 392F to silently destroy airborne mold, bacteria, viruses, pet dander, pollen and common household dust mites in a room up to 450 sq. ft. and 550 sq. ft.. Despite its high internal heat level, the purifier will not change the room temperature. For the highest level of air purification, it is recommended for use 24-hours a day, every day, yet it draws less power than a 60-watt light bulb.
