I find there’s three types of hand dryers: the standard kind that blows really hot air to evaporate the water, the ones that blow strongly to push the water off the hands, and the ones that are supposed to do one of these but don’t. At my university almost all of the hand dryers fall into the third category.
Why are hand dryers like this, and am I somehow drying my hands wrong?
1: most people don’t do a decent job
2: how often do you think those filters get cleaned?
3: splattering tap water all over is also bad hygienic practice
They’re banned in the good hospitals for a reason.
