First time I'm seeing a claim that paper towels spread more germs. Got a source to back that up?

It doesn't seem plausible. After wiping your hands dry the bacteria either stayed on your hands or were transferred to the paper towel. I can't see a path to the air.

Blasting your hands with air fast enough to blow off whole water drops and shatter them would put bacteria in the air.

I presume that when testing their air driers they use a sterile room and thoroughly washed hands in hospital type soap so any bacteria went down the drain and only sterile water was blown into the air

OP edited their post with a link. It's an entirely different topic, it's about germs on paper towels coming from the factory.
