The Dyson Airblade is a hand dryer that pushes water off wet hands with a thin sheet of fast, unheated air instead of evaporating it with heat. It launched in the UK in 2006 and in the US in late 2007.
| Principle | A thin layer of unheated air at around 400 mph (later models about 430 mph) works like a squeegee |
|---|---|
| Claimed drying time | About 10 seconds |
| Maker's efficiency claim | 69% more energy-efficient than conventional hand dryers and 97% more cost-effective than paper towels |
| Main criticisms | Airborne spread of germs and high noise levels, both studied since 2014 |
