Dyson Airblade hand dryers being tested for aerosolisation

How the independent tests worked

Our objective was to see how many aerosols were generated by Dyson Airblade™ hand dryers compared to drying with paper towels, or washing but not drying.

Independent testing was carried out by Airmid Healthgroup in a controlled environment using a sink, paper towels, and Dyson Airblade W+D, dB, V and 9kJ hand dryers. Each experiment was carried out three times with paper towels and hand dryers being used in seperate experiments.

Results proved that each Dyson Airblade™ hand dryer had no significant impact on the surrounding air. This supports previous studies that they're as hygienic as paper towels.

What is aerosolisation?

Aerosolisation is the action of creating aerosols. Aerosols are tiny liquid or solid particles, or a mix of both, suspended in a gas (e.g. air).

Their composition can vary depending on how they are formed and may include bacteria or viruses. Aerosols can vary in size, for example they can be as small as 0.3 microns.

While larger, heavier particles tend to drop to the floor, these smaller particles are more likely to become suspended in the air – or 'aerosolised'. Aerosols are all around us.

Touch-free technology

Dyson Airblade™ hand dryers utilise sensor technology. Engineered for a touch-free, hygienic user experience.

These sensors are programmed to detect and automatically dry hands. So it allows users to maintain a distance between their hands and the machine.

  • Sensor technology on Dyson Airblade Wash+Dry hand dryer

    Dyson Airblade Wash+Dry features infra-red LED sensors to automatically detect the hands for both washing and drying. To switch between wash and dry modes.

  • Sensor technology on Dyson Airblade 9kJ hand dryer

    Dyson Airblade 9kJ features infra-red time-of-flight sensors to trigger HEPA-purified air and are designed for an optimal user experience.

  • Sensor technology on Dyson Airblade V hand dryer

    Dyson Airblade V features capacitive sensors to automatically turn the HEPA-purified air on and off as hands enter the sensing zone.

Proven hygienic by independent testing

Proven in washrooms worldwide

Since the original Dyson Airblade™ hand dryer was released in 2006, they’ve been used by millions of people in washrooms around the world.

Although each machine carries a guarantee of five years, with proper maintenance they’re engineered to continue drying hands for much longer. And unlike paper towels, a Dyson Airblade™ hand dryer won't run out.

    Wash and dry at the sink

    With Airblade™ technology in a tap, there’s no need for users to move to a separate drying area, so less water is dripped on the floor.

    Two 0.45 mm curved apertures create 624 km/h sheets of air that follow the contours of your hands, removing water, in less time.

Frequently asked questions

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 Honk Polytechnic University showed that, when used correctly, Dyson Airblade™ hand dryers actually reduced the bacteria on hands.

Dyson's new independent research into aerosolisation shows that that drying hands with a Dyson Airblade™ hand dryer aerosolises no more than drying with paper towels – and that Dyson Airblade™ hand dryers are hygienic and safe to use.1

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.

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 hands.9 Dyson Airblade™ hand dryers have been proven to be as hygienic in drying hands as paper towels10, but without the environmental damage or high usage costs.11
