The Dyson Airblade Wash+Dry hand dryer's HEPA filter captures 99.97% of particles the size of bacteria as small as 0.3 microns from the washroom air. So hands are dried with cleaner air. Touch-free infrared operation helps prevent the spread of bacteria. Because you don't need hand dryers or towel dispensers on your wall, the Dyson Airblade Wash+Dry hand dryer frees up more space in your washrooms for extra toilet cubicles or other facilities. No waste water on the floor: drying hands at the sink means there's no water being dripped on the floor. Precise infrared zones operate the Dyson Airblade Wash+Dry hand dryer automatically. And because it switches intuitively between water and air, there's no need to touch dirty faucets or buttons, and no drips on the washroom floor. Sheets of high velocity air quickly scrape water from hands, without needing energy-hungry heating elements. Dyson Airblade hand dryers have been certified globally for use in food preparation environments by meeting HACCP International standards.
