This released from Dyson, Inc., the English vacuum company. The first and only such certification for commercial hand dryers has been awarded by the NSF (formerly the National Sanitary Foundation) to the Dyson Airblade hand dryer. The NSF is a world leader in "standards development, product certification, education, environmental protection, risk management, and health protection". Whereas other commercial hand dryers can distribute bacteria, the Airblade contains a HEPA filter. The Airblade also features the ability to dry hands quickly—in 12 seconds or less.
