There are two different types of air dryers: the high-speed “hands-in” dryers and the warm air, lower speed “hands-under” design. Although more expensive as an initial investment, once an air dryer is installed, there is minimal maintenance. Basically, the ongoing cost is just for the energy used to power the dryers.
After installation of air dryers, there is no more worrying about re-stocking towels, battery replacement, paper thrown on the floor, clogged toilets from flushing towels, and frequent emptying of trash receptacles.
However, there is evidence air dryers contribute to the spread of illness. A study conducted by the University of Westminster showed high-speed “jet” air dryers dispersed 190 times more viruses (measured at nine different distances) as compared to paper towels.
Additionally, high-speed dryers can cause water pooling under the dryer, creating a slip & fall risk, as the air blows water beyond the dryer housing.
