Unfortunately it is very much true.

Edit: here's a more recent source.

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.

You're right and I linked a fairly old study. I've edited my comment to add a more recent source.

Kudos.

Findings: Air bacterial counts in close proximity to hand drying were 4.5-fold higher for the jet air dryer (70.7 cfu) compared with the warm air dryer (15.7 cfu) (P=0.001), and 27-fold higher compared with use of paper towels (2.6 cfu) (P<0.001).* Airborne counts were also significantly different during use of towel drying versus warm air dryer (P=0.001). A similar pattern was seen for bacterial counts at 1m away. Visualization experiments demonstrated that the jet air dryer caused the most droplet dispersal.

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.

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.
