Hand dryers are not considered as hygienic as paper towels, and are known to spread bacteria. Standard hand dryers can blow micro-organisms up to one foot while Airjet Hand Dryers can blow them up to 6.5 feet. Measuring bacteria prior to washing and after drying, bacteria on the hands increased 194 to 254 percent with standard dryers and 15 to 42 percent with jet dryers. Standard dryers take 30 to 43 seconds to dry the hands, making cross-contamination more likely. Jet hand dryers take 8 to 10 seconds.
