Excel Dryer, manufacturer of the original, patented, high speed, energy-efficient XLERATOR® hand dryer, is committed to providing the most hygienic hand drying solutions. While the cost-savings and environmental benefits of high-speed, energy-efficient hand dryers are clear, there are many misconceptions about the hygienic efficacy of different hand drying methods. It is important that distributors and end-users are comfortable and assured that Excel Dryer hand dryers are both reliable and hygienic. This page has been created to host educational materials regarding hand hygiene as it relates to hand dryers, including scientific studies, case studies, articles and other resources about proper hand hygiene.
Excel Dryer acknowledges that many studies have also been produced, mostly funded by the paper towel industry, in support of paper towels. However, there are several independent third-party studies that debunk the myth of paper towels being more hygienic than hand dryers.
Several studies have been published in well-known medial reviews on the health benefits and hygienic efficacy of hand dryers.
A study conducted by the Mayo Clinic, a nonprofit, worldwide leader in medical care, research and education, evaluated the effects of four different hand drying methods regarding the removal of bacteria from washed hands. The study concludes that “there are no differences in the efficiencies of removing bacteria from washed hands when hands are dried using paper towels, cloth towels, warm forced air or spontaneous evaporation.”
Another study, conducted by researchers at Laval University in Quebec City and published by the American Journal of Infection Control, evaluated bacterial contaminants found on unused paper towels.
The pilot study found “a large community of cultural bacteria, including toxin producers, can be isolated from unused paper towels.” These bacteria were also found to be capable of transfer to individual’s hands after washing, “which may have implications in some industrial and clinical settings as well as in immunocompromised individuals.”
Specifically, the findings included 17 species of bacteria on the paper towels with the most common being Bacillus, which causes food poisoning.
