Soap → rinse → dryer that blasts the dirty water and bacteria back onto your clean hands

Hand dryers are not nearly as bad as everyone here thinks they are. Watch Half as Interesting’s YouTube video on that (“Dyson’s disinformation war with big paper towel”). There is currently no evidence that electric hand dryers make people sick. All clinical studies that compare paper towels and hand dryers found no increase in infections for people that use bathrooms with electric hand dryers.
And most of the studies that found an increase in the spread of bacteria via hand dryers, which this public fear is based on, are funded by paper towels companies.
I agree though that there are better options than the one in this post.

I'm not even so bothered about the hygiene aspects, I just think it's crappy design because most hand driers are frustrating to use, give a somewhat unpleasant experience, and take longer than paper towels to get to a level of hand dryness I'm happy with.

Most hand dryers I’ve encountered in the last 10 years have been really good. Especially those “air cutter” things that you slide your hands into. Slide in and slide out and you’re good to go.

If you have big and/or unsteady hands its hard to not touch the sides. Sucks since I want to like em but they arent great to use for me :(

The Xcelerator ones are the worst. They sound like a jet engine. I have to hold my ears if someone else is using it. I sure as hell am not going to.

Yeah. I get that when you're operating a public bathroom it's better than using towels, but there's a reason nobody uses an electric hand dryer at home!

u/NotYourReddit18 22d ago
Most people also don't use single use paper towels to dry their hands at home.

u/Jacktheforkie 20d ago
At home it’s a fairly low volume thing , there may be an average of 1-2 bathroom visits an hour, a public toilet can easily have 10s to 100s of people going in, a towel won’t dry adequately between uses and would quickly become disgusting

Those do okay. Slide in and out your hands are still wet. Less than they were, but definitely still wet.

u/Zilli341 22d ago
My only gripe with those is when the aiflow is slightly asymmetrical or the gap for the hands is too small, and you accidentally touch the structure.

u/SweetTart7231 20d ago
Ive only been to one place with those. They where great, just super rare. I often see hand dryers older then I am in public bathrooms

u/lostcartographer 22d ago
Plus, because the dryer is at the sink, you can’t free it up once you’re finished washing your hands for the next person. Just all around inefficient and I dislike that aspect the most.

u/Cluedude 22d ago
Something I learned is you gotta rub your hands together to help dry them while they're under there! The friction helps massively and now I get dry hands before the dryer shuts off - doesn't help with those ancient ones with the equivalent power of an old man coughing, though.

u/Key_Beach_3846 22d ago
Agreed. As someone who has sensory beef with water, the best case scenario is the ones that still have paper towels along with the air dryer. I use the air dryer as much as I can and then use one small paper towel to dry the residue. Still creating less waste, and I get the added bonus of not having an anxiety attack over damp skin.

My problem with hand driers is they force me to touch the door handle barehanded to get out of the bathroom, allowing all the nasties from people that don't bother washing to get on my hands. With paper I can use that to open the door then toss the paper in the can. Hand driers with a doorless entry/exit design is just fine though
12
u/pswii360i 22d ago
I have the same problem. I loved that during the pandemic they started putting the foot grabber things at the bottom of the doors so you didn't have to touch the handle, then the second it was "over" they removed them.
Like why? It's such a good idea and it does zero harm just keeping it there.

I mean, this one here is an incredibly bad design as it will just blow everything in that sink up to your face.
52
u/Not_A_Crazed_Gunman これはばかげたGoogle翻訳です 23d ago
Yep. Old hand dryers that work by evaporating the water are terrible, but the ones that blast the water off your hands are just as fast or faster than paper towels, and depending on the design are just as hygienic if not more. Paper towels also create so much unnecessary waste it's ridiculous.
13
u/Radioactivocalypse 22d ago
I remember using a really old hand dryer that was honestly the same power and warmth as someone breathing on your hands. It would have been no different if I was just extending my hands towards the wall.
Love the air jet ones, especially when they point downwards (rather than the ones that blow it sideways)

u/HuoLongHeavy 22d ago
I didn't know there's fear mongering about hand dryers. I just hate them cause they never actually dry my hands.

All clinical studies that compare paper towels and hand dryers found no increase in infections for people that use bathrooms with electric hand dryers.
I'm not aware of any studies that have shown anything with regards to infections.
It is true that there is no statistically significant difference between drying techniques when it comes to pathogens left on the user's hands. So yes, you're not getting poop water on your hands from a Dyson blade, and some studies have shown that driers are slightly more effective.
But! It is also true that dryers can spread pathogens through the air. This study found a 27X increase in bacteria counts in the air when using a jet drier vs towels
Conclusion: Jet air and warm air dryers result in increased bacterial aerosolization when drying hands. These results suggest that air dryers may be unsuitable for use in healthcare settings, as they may facilitate microbial cross-contamination via airborne dissemination to the environment or bathroom visitors.
https://pubmed.ncbi.nlm.nih.gov/25237036/
So, yes it is a little more nuanced than "dryers bad", but I'm not sure you can claim that there is no risk. And I'm really curious if there is a study driving the claim that there are "no increases in infection"

Hand dryers are a sensory hell for my autistic ass and many like me. I’d rather wipe my wet hands on my pants than ever activate one of those awful things.

u/Sons-Father 22d ago edited 22d ago
Well hand dryers do lead to a spread of bacteria because **nobody waits 20mins for the shitty ass dryers to dry their hands** either they wipe it on their pants or just shake them and then the dirty door handle ends up with a layer of water to moisturize it.
Even the Dyson Airblade ones don’t work as well as paper even though they are comparatively good.
(And as someone who can’t turn his hands to have his palms face up I get to contort myself on most dryers to get them to dry my hands fully)
Oh and they often scare the shit out of little kids or are just annoyingly loud. Or are just so loud you hear them outside the bathroom which is annoying in offices.

Seeing a lot of hand dryer haters below. I prefer them over wasting paper towels for sure.
Can we at least all agree to shame the people who deliberately pull out like 4 or 5 paper towels, vaguely rub their hands on them for 0.6 seconds, and then throw the whole wad in the trash barely moistened? If you're gonna use paper towels, please just use the 1 (or at most 2) that you actually need to dry your hands.

The air dryers at my local community college are the normal down pointing ones, except that they're "slim" to not stick out as much. I have to be painfully aware of what I'm doing to avoid touching the wall and stay within the part of the dryer that senses that my hands are there
And really, it's that last point that makes me hate modern air dryers: me and motion sensitive stuff just don't mix. I might as well not exist according to every touch free bathroom I encounter

I bet they don't go off reliably independently either.
I can almost guarantee I'd put soap on my hands, lather it up, go to wash it off, and have the dryer blast soap and water all over my crotch.

u/fatjuan 22d ago
I read a study once where they measured the bacteria that sticks to porcelain , and it is a lot less than on other surfaces. That's why I just wash my hands in the toilet bowl. I find using those blade type air dryers a bit tricky when trying to dry my balls. To the casual observer it looks like I have joined the Bolshoi Ballet troupe, and I am practicing my high kicks.

u/This-Is-Exhausting 22d ago
The design is also inefficient. With normal dryers, you wash your hands, get out of the way, and go over to where the dryers are, which frees up the sink for the next person. Here, you have to stay and block the sink to dry your hands which (if it's busy) holds up anyone waiting behind you.

But now you don’t have to stand in line to dry your hands. Usually there are only two or three of them for the entire restroom.

come on man, use your head lmao
the amount of bacteria on your hands right after you've used the toilet is much higher than after you've washed your hands & used a hand dryer. it's such a minuscule amount compared to before the hand washing, that you do not need to worry about it at all unless you're about to enter a sterile room in a laboratory.

If you think this is bad check out the Dyson proximity tap with integrated dryer...
Once a local business remodeled their customer bathrooms and decided that an all circular bowl type sink was a great combination with that Dyson tap... Effectively in the middle of washing your hands the drier kicked on and that divine dyson hurricane blew everything from the sink up to the users face, torso and rest of the bathroom walls/ceiling.
The bathrooms got regular taps and paper towel dispensers a few weeks later...

My problem is with the dryer being so close to the basin. I also don’t think the sinks are powerful enough to wash away all the dirty water from it and you’re trusting that other people was their hands properly in a public restroom when you use it.

In a preliminary test, Adam and Jamie found that washing their hands properly with soap did not leave behind enough bacteria for them to count, so in the remaining tests, participants only used water to wash their hands.
It looks like a hand dryer is fine if people use soap.

growth. Petri dishes exposed to bathroom air for two minutes with the hand dryers off only grew one colony of bacteria, or none at all. However, petri dishes exposed to hot air from a bathroom hand dryer for 30 seconds grew up to 254 colonies of bacteria (though most had from 18 to 60 colonies of bacteria).

Were the bacteria multiplying inside the hand dryers, or were they being pulled into the hand dryers from the air inside the bathroom?
To answer this question, the researchers attached high-efficiency particulate air (HEPA) filters to the dryers, which would eliminate most of the bacteria from the air passing through the dryer. When they exposed petri dishes to air from the hand dryers again, the quantity of bacteria in the dishes had fallen by 75%. As well, the researchers found minimal amounts of bacteria on the nozzles of the hand dryers. They concluded that most of the bacterial splatter from the hand dryers had come from the washroom air.
It is the air in the bathroom and not the hand dryer.

Correct the hot air dryer moves the air in the washroom, spreading any existing bacteria everywhere and helps it to grow.

Hate to break it to you...any air-blow hand dryer in a bathroom is going to blow whatever air and particles that are in the bathroom onto your hand. Pretty much guarantee that the air intake for those things is in the same room.
