Studies show that washing your hands with soap and drying with paper towels is far more efficient and hygienic than drying with electric hand dryers.
Have you heard of toilet plume?
In a public restroom you have two options for drying your hands: use an air dryer or a paper towel. Air dryers are generally thought to be more eco-friendly, but the truth is, they are actually less hygienic and contribute to more environmental contamination. This is because of “toilet plume.”
After a toilet is flushed fecal droplets linger in the air. Air dryers recirculate those droplets when you dry your hands, making it easier to spread germs.
