Researchers: Dyson Hand Dryers Spread Viral Germs

Beth Mole, reporting for Ars Technica:

By far, the jet dryer was the biggest viral spreader in all measurements.

Clumping the data from all six heights together, the Dyson produced 60 times more plaques than the warm air dryer and 1,300 times more than paper towels. Of the viruses launched by the jet dryer, 70 percent were at the height of a small child’s face.

Looking across the distances tested, most of the jet dryer-launched viruses landed about 0.25 meters away. But at three meters, the number of plaque-forming viruses spread by the jet dryer was 500-fold greater than that from the warm air dryer (paper towels launched zero to this distance). In total across the distances, the jet dryer spread 20 times more viruses than the warm dryer and more than 190 times more than the paper towels.

It’s just one research project, but it seems pretty compelling. I’ve always preferred paper towels to any sort of air dryer. Speaking of which, from the DF archive: “How to Use a Paper Towel” — one of my favorite links ever.
