Turns out those fancy Dyson dryers are actually doing a bit more harm that good as they say.
According to a recent study conducted by the University of Westminster, they found that rapid dryers such as the Dyson Airblade (which blows air at around 430mph) actually spreads germs over much greater distances as compared to traditional hand dryers and paper towels.
From the stats, the “rapid dryers” spread germs as far as 3 meters (a little over 9 feet) away from the dryer as compared to just 75cm (29.5 inches) with regular hand dryers and 25cm (9.8 inches) with the use of paper towels. In terms of spread, they team dipped their hands in water containing a harmless virus called MS2 and found that the spread was 1,300 times more when they used a rapid dryer versus hand towels, and 60 times more when they used conventional hand dryers.
The spread factor was measured by setting a target 40cm (15.7 inches) away and taking measurements with each hand drying method.
Dyson has fired back, claiming the study was conducted under “artificial conditions” where unreasonably high levels of the virus were used.
Interestingly enough, it does appear that the bigger problem with germ spread is as a result of poor hand washing techniques rather than hand drying, where as many as 1 in 4 women and 1 in 2 men did not wash their hands at all after using a washroom.
I personally haven’t been too much a fan of the Dyson Airblade dryers as I’ve ended up touching the sides at some point by accident, and it doesn’t exactly dry my hands as fast as they claim it should.
