Remember kids, when making graffiti, always cite your sources.
Is this true? Seriously curious.
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.
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.
But I thought all the piss sterilizes them.
Good time to share How to use one paper towel (to thoroughly dry your hands in a public restroom).
Shake. Fold. It really does work.
Can’t watch at the moment; is this the guy who says to shake 7 times before you dry?
I’ll just leave this here:
Hygiene associated with the product has been questioned in research by the University of Westminster Trade Group, London and sponsored by the paper towel industry the European Tissue Symposium
It’s ok to be cautious, but if the data is accurate then it doesn’t matter much.
Also, how is their research any worse than the one sponsored by Dyson, who is trying to sell overpriced hand dryers.
Anyone who has ever seen one of these more than a few weeks old knows how disgusting they get because cleaning crews were never trained to clean them. I’m assuming that isn’t considered in Dyson’s version of the research at all. There’s one in a bathroom in my area that is covered in mold.
