A question for the ages. When in public restrooms is it better to dry your hands with the electric dryer or use the paper towels? The answer is surprising and makes sense when you think about it.
Several studies comparing hand-drying methods have found that jet-air dryers blow microscopic drops of water containing bacteria around the bathroom. Researchers concluded that jet- or warm-air dryers “may be unsuitable for use in healthcare settings” since they could facilitate the spread of germs from one person to another.
This alone makes paper towels the better option, especially the hands free types. And paper towel machines are much quieter.
