Luckily, he has the solution: the Airblade Tap, a tap system with inbuilt air dryers which blow cold air at miles per hour over the hands to "scrape" them dry, which he says will make huge cost and environmental savings compared with warm air dryers and paper towels. Our method is more like a windscreen wiper, except that the hand is a much more complex shape than a windscreen.
The company has also redesigned its Airblade hand dryers, and introduced a new smaller wall-mounted dryer as it targets the huge corporate business for washrooms in offices, restaurants and hotels. This video can not be played To play this video you need to enable JavaScript in your browser.

In the study , published in the Journal of Hospital Infection, the scientists collected bacteria across a dozen hospital restrooms in the UK, France and Italy. They mentioned, in their paper, that they used a Dyson vacuum to hoover up dust, to take it back to the lab for analysis.
During the meetings, a Kimberly-Clark representative updated the others about early progress. Kimberly-Clark did not respond to multiple requests for comment for this story. The rep was involved in contacting other scientists to secure their participation, and the task force treated her as its main point of contact with the lead scientist. They were confident they would have something to communicate. Hand dryer firms have sponsored studies of their own, engaging as closely with those researchers as ETS did with its own.
In fact, in one Dyson-funded paper, published in in the peer-reviewed Journal of Applied Microbiology, a Dyson scientist named Toby Saville was one of four authors arguing that the Airblade was better at reducing bacterial transfer than the older models of hot air dryers.
The scientists sampled six different parts of the restrooms they visited. Only in two of these locations — on the floors, and on the surfaces of hand dryers or towel dispensers — did washrooms with dryers show appreciably more bacteria than those with paper towels. Even then, those higher numbers were half of those typically found on our own bathroom floors at home.
But the paper and its attendant press coverage had their effect. Redway, a microbiologist, published his first paper on the subject in , on commission from the Association of Makers of Soft Tissue Papers. In his most recent experiment, published in , Redway and a colleague tested how widely paper towels, hot air dryers and jet dryers could disperse viruses. Then the scientists put on gloves, soaked their hands in a virus-rich broth and dried them with one of the three options.
Petri dishes of agar affixed to the cardboard family, which was positioned at different distances of up to three metres, captured and revealed any dispersed viruses. Not surprisingly, the high-speed Dyson was found to be slinging viruses the furthest. I asked Redway.
Surely no one in a normal restroom bathes their hands in a viral solution before moving on to a jet dryer? But this was just a model, Redway said, and they had treated all three drying devices the same. The course of the hygiene debate fluctuates between levels of idealism and pragmatism. Redway thinks restrooms should be as free of risk as possible. An argument like that stirs Redway up; he appeals to common sense and our knowledge of human nature.
A paper towel prevents that. The question then becomes: how much do we trust the hand-washing and hand-drying inclinations of those who have preceded us into a washroom? Our loo culture reveals our habitual laziness, our perpetual hurry; it is our own tendencies, rather than hand dryers or paper towels, that must be blamed for our germ-ridden restrooms.
The rancour between Redway and Dyson has erupted into the occasional strange confrontation. One of the Dyson executives present remembered the incident. They tried initially to stop us from going in. He recalled one of his colleagues lobbing a question at Redway.
It reminded me of something George Campbell had said. In the Dyson offices in Chicago, where he once worked, the lobby washrooms had Airblades but also paper towels. I asked Redway what he would do if he went into a restroom and saw only a hand dryer. A jingle of keys emerged, then some coins, and finally, a crumpled sheet of paper towelling.
The founder, Sir James Dyson, had been a stubborn Brexiter back in ; three years later, as Britain was floundering in search of a way to leave the European Union, Dyson announced that he was moving his headquarters to Singapore.
The two media officers I met must have been relieved that they needed to talk about hand dryers, not Brexit. They led me through the sights: a giant Faraday cage, to test devices for electromagnetic interference; an anechoic chamber to refine noise levels, so quiet I thought I heard my blood wash around my body; a lab to test filters.
It is the one that sits above a sink and is shaped like a cartoon arrow; the tip of the arrow is a faucet and dispenses water, and the two tines of the arrowhead blow air. They thought it was a weird-looking urinal. So the company tried to storm paper towel territory, where it found itself a fight. The stream of scientific papers on hygiene quickened then, the former employee said. At its most audacious, the hand dryer is an expression of faith in the mechanical — in the premise that no cubic inch of our day is too trivial to remain unimproved by technology.
