12 second dry time: Many people give up when using a slow hand dryer. But damp hands can spread up to 1,000 times more bacteria than dry hands. Testing based on NSF Protocol P335 proves that Dyson AirbladeTM hand dryers are the fastest. The Dyson Airblade V hand dryer dries hands hygienically in 12 seconds. Dyson Airblade Technology – The most hygienic hand dryers. Most other hand dryers are unhygienic. They don’t filter bacteria from the restroom air. They suck in dirty air then blow it back onto hands. The Dyson Airblade V hand dryer uses two HEPA filters to remove 99.97% of bacteria at 0.3 microns from the air used to dry hands. So hands are dried using cleaner air, not dirty air. Only Dyson AirbladeTM hand dryers are certified hygienic by independent public health specialists, NSF international. No other hand dryers meet every part of the NSF Protocol P335. As well as having a fast dry time and HEPA filters, the Dyson Airblade V hand dryer also has touch-free operation and an antimicrobial coating.
