Dyson Appliances Airblade hand dryers are the first to pass all of the strict criteria under the NSF Protocol P335. The Protocol sets out the standards a hand dryer should meet to be considered hygienic.

The standards include air filtration, the use of unheated air, drying time and touch-free operation.

The Dyson Airblade uses a HEPA filter which, combined with an anti-bacterial primer removes 99.9% of bacteria.

The HEPA filter removes bacteria from the air used to clean hands meaning the air used to dry hands is hygienically clean while the primer reduces surface bacteria and lowers the possibility of surface contamination.

Wet hands can pick up and transfer up to 1,000 times more bacteria than dry hands however the Airblade hand dryer is able to dry hands in ten seconds which further limits bacteria levels.

As users don’t need to rub hands while using the Airblade, bacteria in lower skin layers is not brought to the surface.

NSF International, the leading independent public health specialists agree that the Dyson Airblade passes their strict standards under the NSF Protocol P335 and is a true hygienic hand dryer.
