Hand dryers are electric machines found in public restrooms that dry the user’s hands by blowing warm air over them. An more sustainable and hygienic way to dry hands, hand dryers can be operated with the push of a button or function automatically via integrated sensors. Hand dryers are preferred as they remove paper waste, and require less maintenance and management compared to the disposal of paper towels. The earliest hand dryer was patented in 1921, and it was controlled by a floor pedal. New hand dryer models today aim to blast air unto both sides of the hand, pushing the water off, rather than evaporating it.
