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.

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.
Dyson Airblade 9kJ features infra-red time-of-flight sensors to trigger HEPA-purified air and are designed for an optimal user experience.
Dyson Airblade V features capacitive sensors to automatically turn the HEPA-purified air on and off as hands enter the sensing zone.

University of Bradford

A study by the University of Bradford, published in the Journal of Applied Microbiology⁵ found that Airblade™ technology is as hygienic as paper towels.
However, there are practical difficulties in the supplying and disposal of paper towels that may result in the dispersal of bacteria. University of Bradford logo

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.
