Frequently asked questions
Do Airblade jet/hand dryers spread germs?
There are a number of studies used by the paper towel industry to support bold and inaccurate claims. In general, these studies were not conducted under conditions or scenarios that simulate real life or an actual situation that a person would reasonably experience when using a Dyson Airblade™ hand dryer. Researchers that conducted these studies were only able to achieve such a result by grossly contaminating their hands with bacteria and viruses, and drying them with a Dyson Airblade hand dryer without washing their hands first. Conversely, research by the University of Bradford showed that when used correctly Dyson Airblade™ hand dryers reduced the bacteria on hands by up to 40%4.
What does HEPA stand for?
HEPA stands for High Efficiency Particulate Air. To be a genuine HEPA Filter, like fitted in all Dyson Airblade™ hand dryers as standard, the filter must pass test standards EN1822-5 and IEST-RP-CC001.6. Any filter which does not state it is a HEPA filter may not be proven to work to such high levels of efficiency.
Should I use a paper towel or hand dryer when drying hands? Which is more effective?
Hand washing is a crucial way of reducing the spread of bacteria and viruses. Drying hands properly is an important step in that process as damp hands can spread up to 1,000 times more bacteria than dry hands1. Dyson Airblade™ hand dryers have been proven to be as hygienic in drying hands as paper towels8, but without the environmental damage or high usage costs.9
