Is this a joke? Where have you been the last two years?

Do you know something I don't? My understanding it that aerosols that leave your mouth when you speak can obviously contain virus. But there's no logical reason why simple warm air that has no aerosols suspended in it that gets cooled down and condenses into particles would contain virus.

Your breath (what you exhale) always contains substantial amounts of moisture (and yes, potentially virions). It does not matter if you speak or not. It does not matter if the environment is cold or not. There is no "simple warm air" out of your lungs.

I agree with mtn_nerd, you must be trolling. Considering your choice of words, you're probably well aware of that.

No one washes their hands perfectly (e.g., ready for surgery), so when you dry them there’s still a lot of bacteria present. Dyson dryers aerosolize those particulates, and they do it far more than other dryers. Think of it this way — they don’t dry your hands, they blow the water off. Where does the water go? All over the bathroom. Dyson dryers disperse fluids up to 3 meters away. https://arstechnica.com/science/201…

To be fair, other hand dryers only do better on this metric because they don't actually remove the water from your hands.

Regular hand dryers (hot/dry airflow) literally make the water evaporate off your hands. How is the water not removed?

What's the issue with the dryers? You use them to dry already-washed hands and the dryers themselves aren't very close to the toilets.

That assumes everyone thoroughly washes their hands, which is unlikely. Dyson hand dryers, specifically, always have a nasty puddle of water at the bottom of their drying "crevice" in busy bathrooms.

That's just a bonus, the main issue with them as other comments have noted is that they shove the water off of your hands using their "air blades".

This aerosolises a significant fraction of that water (the rest goes and collects in the puddle you speak of), spreading it all over the room.

More classic driers primarily work by evaporation, and furthermore direct the air stream downwards (to the floor) rather than sideways (across the room).

But you just washed your hands. Where are the bacteria coming from?

"washed" Have you seen people in the real world?

Even assuming they're washed correctly (entire song thing with all the trimmings), a bathroom sink is not a steriliser.

The breath you see in cold weather is not aerosols but condensed moisture. I don't know how pointing out this trivial fact can be construed as trolling.

Ask my wet pants and the line of people behind me every time waiting to do the same move.

There is a large, whiny portion of HN who were so severely injured by the COVID-19 fear porn that they uncritically consumed that they see viruses in their sleep still, two years later. It’s quite sad.
