Installing warm air hand dryers in public restrooms cuts down significantly on maintenance. On average, automatic hand dryers need to be serviced only once a year, and require nothing else in the way of basic maintenance unless something unforeseen, such as a power outage, occurs. No one needs to check the supply of paper towels each day or replace them as needed. The air dryers are ready to use 24/7 and require almost no attention once they are installed except for an occasional wiping to remove fingerprints.
In addition, air dryers use very little electricity; data from one hand dryer manufacturer suggests that an average restaurant may spend less than $50 annually to operate hand dryers.
