    HEPA filter

    The HEPA filter captures 99.95% of particles2 as small as 0.1 microns from the washroom air. So hands are dried with cleaner air. Antibacterial coating and touch-free operation helps to prevent the spread of bacteria. So Dyson Airblade™ hand dryers meet every part of NSF Protocol P335, which defines the criteria for hygienic hand dryers.
