Comment on Why do so many hand dryers not dry hands? Am I doing something wrong?

  How are they unsanitary?

    Someone else linked this in their comment but the air in those dryers has to come from somewhere… if it’s coming from the bathroom, where there are no lids on the toilets and aerosolized poop particles are sucked into the dryer and right onto your hands, I would lean towards that being unsanitary. This is also why it’s important to put the lid down before you flush at home, to avoid all those particles floating around onto anything exposed in your bathroom, like maybe your toothbrush or towels.

    The theory is that they aerosolize the water and whatever was on your hands, but if you did a decent job cleaning them, it’s not really a problem.

      1: most people don’t do a decent job

      2: how often do you think this filters get cleaned?

      They’re banned in the good hospitals for a reason.

      I think it’s because they vacuum air from a public restroom and blow it all over your hands.
