When it comes to the standard air blade, I don't think your concerns about hygiene are valid. You have, after all, just washed your hands. Any "germs" have already been killed and washed away by soap and water. If anything is blowing on to your face (not the case in my experience), it's just water vapour from your own hands.
There is, however, another Dyson design where the hand dryer is integrated into the sink/tap. This one actually blows particles/droplets from the sink up towards your face, which does give me some hygiene concerns:

You can find these in some of the washrooms at Heathrow airport.
- Jonnax 7y agoIf you ever see an air blade in a less often cleaned public toilets there's usually pool of gunk at the bottom of the unit. The musty smell that ensues when it's on makes me believe that the dirty dampness is being accelerated into a cloud of bacteria.
- onli 7y agoSoap and water does not fully kill the hand bacteria (which is good, kind of). And there are definitely possible problems with bacteria from those air dryers, see https://www.health.harvard.edu/blog/the-bacterial-horror-of-the-hot-air-hand-dryer-2018051113823 https://www.health.harvard.edu/blog/the-bacterial-horror-of-... - though there seems to be no real consensus here.
- Reason077 7y agoModern hand dryer models, including Dyson air blades, do often have HEPA filters on their air intakes.
