Are air hand dryers dirty?

Looking for an answer to the question: Are air hand dryers dirty? On this page, we have gathered for you the most accurate and comprehensive information that will fully answer the question: Are air hand dryers dirty?

Hot-air hand dryers are less sanitary than paper towels in public restrooms. In a preliminary test, Adam and Jamie found that washing their hands properly with soap did not leave behind enough bacteria for them to count, so in the remaining tests, participants only used water to wash their hands.


It's worth remembering hand dryers don't create microbes and there's usually only minimal bacteria on their nozzles, too. In many cases air dryers can even be fitted with filters that help clean and remove contaminants from the air.


Although hand dryers do produce carbon emissions, studies have shown warm air dryers (which rely on evaporation) generate up to 70 per cent more emissions than newer, fast jet dryers (which force out a rush of cold air). Environmentally speaking, warm air dryers and paper towels perform roughly the same, on average.


When they exposed petri dishes to air from the hand dryers again, the quantity of bacteria in the dishes had fallen by 75%. As well, the researchers found minimal amounts of bacteria on the nozzles of the hand dryers.
