Hygiene
If a hand dryer doesn't have NSF or HACCP accreditation, it's not certified hygienic.
NSF International, leading independent public health specialists, agree that the Dyson Airblade™ hand dryer is the only hygienic hand dryer and the first to meet NSF Protocol P335 and meets every criteria HACCP set, making it the only truly hygienic hand dryer.
Dirty air in, clean air out
A HEPA filter removes 99.9% of bacteria from the air used to dry hands. To illustrate how this works, we set up a special test in a ‘smokebox’ to show how the HEPA filter in the Dyson Airblade™ hand dryer removes bacteria from the airflow. This ensures the air that dries your hands is hygienically clean.

No hand rubbing
Users don't need to rub their hands together. Bacteria in lower skin layers are therefore not brought to the surface.
Speed of drying
The Dyson Airblade™ hand dryer takes just 10 seconds to dry hands. Wet hands can pick up and transfer up to 1,000 times more bacteria than dry hands.
Anti-microbial coating
External surfaces are infused with anti-microbial additives to reduce surface bacteria by 99.9% and lower the possibility of user contamination.
What is NSF Protocol P335?
The lengths we go to (and this is only one test!)The protocol sets out the standards a hand dryer must meet to be considered hygienic.
The criteria for a hygienic hand dryer include:
- Air filtration – Dust and bacteria must be removed from the air used to dry hands.
- Unheated air – The air used shouldn’t be heated up. Warming moist bacteria can increase their reproduction rate. Warm or hot air can remove beneficial oils from the skin.
- Drying time – Hands must be dried in 15 seconds or under. Damp hands pick up and transfer up to 1,000 times more bacteria than dry hands.
- Touch-free operation – The hand dryer must start and stop automatically.
Only the Dyson Airblade™ hand dryer meets all these criteria for a hygienic hand dryer.
