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.

Dyson further analysed the results of this work and wrote a paper, which has been peer-reviewed and published in Frontiers in Public Health. The study concluded that drying hands with jet hand dryers does not significantly increase aerosols or bacteria in air compared to walking and washing hands or drying hands with paper towels.
