A number of studies are 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 gloved hands with bacteria and viruses, and drying them with a Dyson Airblade hand dryer without washing their hands first. Conversely, research studies by the University of Bradford (UK) and by the Hong Kong Polytechnic University showed that, when used correctly, Dyson Airblade hand dryers actually reduced the bacteria on hands.
Dyson's new independent research into aerosolization shows that drying hands with a Dyson Airblade hand dryer aerosolizes no more than drying with paper towels – and that Dyson Airblade hand dryers are hygienic and safe to use.²
