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?
I once found a random food court bathroom that has hand dryers that work amazingly well, and I was genuinely surprised by that when I stumbled on it. I’m guessing it probably is just more expensive or uses more power or something and places cheap out on them.
