The first is that hand dryers provide dramatic cost savings over paper towels over time. Although some people may say hand dryers require the upfront investment of purchasing the unit, you have to admit paper towels must be purchased often and in bulk especially when it is in a company or a large mall. Secondly, paper towels also drive up restroom management costs, requiring maintenance staff to refill paper towel dispensers and clean up paper towels left on floors, in the toilet, or in other inappropriate areas. Plus, paper towels are less sustainable for the environment. The reality is as long as hands are washed and dried effectively both hand dryers and paper are safe. Hand dryers win massively when it comes to environmental impact, operational efficiency and cost.
