Many people are unaware of this but Hand Dryers get disgustingly dirty due to their design and the nasty environment theyโre in
All you have to do is flip the blower over
These units pull air from the room and to blow on your hands. Public restrooms have high humidity, aerosolized particles from toilets like fecal matter and bacteria get airborne when flushing. So does dust, lint, soap scum, skin cells, hair, and mineral deposits from water. Over time, this stuff gets trapped inside
But it gets even worse, there are real studies on this. Itโs a real, well-documented issue
Studies have shown hand dryers can blow out bacteria, sometimes including fecal bacteria, onto clean hands because theyโre circulating contaminated air
I never use these anymore
