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

Well, if you scrub your hands thoroughly with a lot of soap for at least 30 seconds it could work. Last time I saw anyone doing that was in 2021 during corona hehehe.

Given the issue is fixed by putting HEPA filters on the intake of the dryers, it indicates the bacteria is coming from the air in the bathroom, not wet hands.

That Harvard article is what I linked above. It’s where I found that the HEPA filter on the intake works well to reduce bacterial spread.
