Electric hand dryers are health risk, study claims

摘要

Scientists at the University of Westminster have found that electric hand dryers can dramatically increase the number of bacteria on people's hands after washing and contaminate washrooms. As a result they would not recommend that electric hand dryers are installed in locations where hygiene is of paramount importance. The research, commissioned by the European Tissue Symposium (ETS), studied three hand-drying methods: paper towel, warm air dryer and the Dyson Airblade dryer.
