For years, the only alternative to paper-towel rolls in restrooms was small, impotent hand dryers. While they did save money and were better for the environment, the best they could do was leave your hands still pretty damp.

The powerful directed jets of air produced by the Airblade would quickly and effectively remove any water from the users hands, often leaving only the sensation of wetness.
