Edit: here's a more recent source. permalink fedilink source parent hideshow 4 child comments replies: [–] daddy32@lemmy.world 47 points 2 years ago* (2 children) This is not hot air though, so the cited source does not apply. Edit: but it does link to more relevant study towards the end, comparing different means of hand drying. permalink fedilink source parent hideshow 4 child comments replies: [–] Mannivu@feddit.it 34 points 2 years ago (1 child) You're right and I linked a fairly old study.

A similar pattern was seen for bacterial counts at 1m away. Visualization experiments demonstrated that the jet air dryer caused the most droplet dispersal. permalink fedilink source parent hideshow 2 child comments replies: [–] SmoothOperator@lemmy.world 4 points 2 years ago Isn't the point to get bacteria off your hands? Isn't it better to have them in the air than on your hands? It's a lot more likely I'll eat something I touched than something that's been sitting in bathroom air. permalink fedilink source parent [–] Artyom@lemm.ee 3 points 2 years ago They used a jet air dryer, those are the shitty ones that spray everything everywhere. Of course it'll be worse. I'd like to see how a dyson air blade hold up under that kind of test. permalink fedilink source parent
