Tabletop air purification. Designed to purify the air in an individual room, purAir 500 uses three advanced technologies to eliminate bacteria, viruses, odours, smoke, pollen, mold, pet dander and more. These technologies help to sanitize everything in the air, embedded in walls, ceilings, floors, furniture, clothing, on counter tops and other surfaces. Operation is just as simple as its design; choose the continuous setting for a constant clean or use the burst setting’ automatically timed increases in purification to deal with tougher odours.
