NY Times article asking that question with info from different studies and their sources.

The Dyson study claims it’s less than paper towels. Mayo Clinic’s study from 19 years ago claims it is no different than paper towels. Others have claims/findings that say it is far worse, though some sources are dubious. I’m sure harder googling would reveal a more recent and comprehensive study on it.

Some of it could be a maintenance issue or malfunctioned dryer. Kind of like soda fountains where they aren’t cleaned in some places like they are supposed to be.

I doubt I can find it again, and maybe somethings changed over the years, but I remember reading a study that found that using a hand dryer is dirtier than using a paper towel. The filters in those things, which get cleaned... probably never, are breeding grounds for bacteria. Those “air knife” ones with the round plastic body are even worse; they blow the bacteria from one persons hand onto the device itself then onto the next users hands.

Older people often have more sensitive ears, in the sense that loud noises hurt their ears more easily. Since they usually have some degree of hearing damage, it might seem intuitive that they could withstand louder noises more, but the opposite is true. Hearing damage makes them more susceptible to discomfort from loud noises.

ever since then, my hearing in my left ear has gotten worse and worse. people can startle me at work bc I'll be at my desk and they'll come up from behind on my left side and I can t hear them until their right beside me and its like they appeared oit of nowhere.

Yup.

It's also for ease of cleaning the bathroom.

Please bear in mind that people will definitely take paper-towels and clog sinks. Or urinals. Or they'll just shove them into the toilet. Or they'll steal them. Or they will get them wet and throw them at the wall.

Hell, at my high school they had to take down the mirrors because someone kept going in and breaking them. And then someone filled the soap dispenser with piss. And of course the infamous completely broken toilet.

I've gone into public bathrooms that have papertowels instead of hand-dryers, but they are probably most often frequented by people that are past the age of "I'm going to be a complete asshole to the custodian."

Why does it matter if there are paper towels or not? A large enough amount of toilet paper will still clog up anything in a bathroom.

I remember in school it was common to see wads of toilet paper stuck everywhere, like huge spitballs. Ceiling, walls, one time they even blocked out the window. I think the paper towels were too stiff and they just kinda peeled off. But if you really sop down some toilet paper it will blow up if you throw it hard enough.

Being a janitor in a school must be horrible.

Toilet paper is at least designed to break down in water, Paper Towel isn't--or you couldn't really dry your hands with it.

So paper wads aside, if people try flushing Paper Towel you have a worse issue on your hands than scraping paper bits off the ceiling.

I used to be responsible for cleaning restrooms and people would absolutely go bananas with the paper towels. They'd fill the sinks, urinals, and toilets with them as well as simply throw them all over the place. It took me longer to clean up the paper towels than it did the do all of the other cleaning combined.

From the cleaning perspective handryers are an absolute godsend.

Had a completely different experience when I was doing janitorial work for a big mall. We had to spend more time cleaning because the dryer was shooting water everywhere and creating puddles during peak hours, as well as leaving disgusting traces on the wall. Plus, people were using TP to dry their hands and leaving crumbs on every countertop and on the floors. The only thing that we had to do with the paper towels was change a few rolls a day and change the trash maybe one time more per day than after they phased them out.

Their point isn't to dry your hands or keep the bathroom air germ free

In a restaurant where employees are expected to wash their hands before returning to work, this absolutely should be the concern. If you're licensed to sell food, you shouldn't be allowed to have these.

Plus.. how are you keeping your hands clean when you open the door to get out? That's the real reason I hate those air-dryers.

Interestingly, the germ problem was a flawed study funded by the paper towel corporations that tested residual germs on the hands and air of someone who went to the washroom, ran hands under water with no soap, then used the air dryer. They compared this to someone who properly washed their hands and used paper towels. So bigger lesson is just wash your hands properly and read the study not the headline.

RAproblems

That kind of make sense. Soap is a surfacant and helps lift residue and germs. If you're only using water, you need to depend on the friction from the paper towels to remove the grime and germs.

Does it take previous users of the air dryer into account though. That's what really concerns me, people getting their nasty hands all over the machine, then the air blowing it onto my hands.

thiskirkthatkirk

Right, that’s the real comparison rather than just looking at how the two perform under ideal circumstances (paper towels vs clean hand dryer). Anyone who has worked in healthcare can tell you that it’s not just about how you wash and dry your hands, it’s also about not touching dirty surfaces during the process which is why you don’t turn off a sink with your bare hands but instead use a clean paper towel.

thiskirkthatkirk
5
1 week ago

But as far as I’m aware the concern isn’t so much effectiveness of the drying method itself, it’s about what is less likely to contaminate your hands with new bacteria after you’ve just washed them.

The thought has always been that others who didn’t use soap could leave behind bacteria in the air dryer which could then be blown onto another users hands, so the important thing to look at is how the air dryer performs in a real world scenario where people do a bad job of washing their hands.

You're supposed to fully lather both hands and up your wrist for 20 seconds to get the full effect of hand soap.

There's several charts and tables that require reading several poorly written documents from the 1980s. But basically OSHA "recommends" exposure over 100 decibels for less than 15 minutes per, and never more than 115 decibels. The law is 85 decibels when averaged out over an 8 hour day, but only applies to employees at a workplace.

The highest I'm aware of is 115dBA for 15 minutes. I don't know what the standard is for acute sound exposure.

UL for medical devices is 80dBA over 24 hours. Non-weighted peak measurements are at 140dB or 120dB for children.

Source: IEC 60601-1, 60601-2-52 Clause 9.6.2.1

I realize hand dryers aren't medical devices. The 80dBA over 24 hours is considered the "irreparable damage threshold". The 140dB/120dB mark is for instantaneous noise.

I'm curious to know the CPB of a hand dryer. I'd be willing to bet there are prominent bands in the 1k-4k range.

Edit: I do sound at a medical device manufacturer. (testing/analysis/engineering)

One of the hand dryers in the women's bathroom at our local Target is literally within inches of the baby changing station. If you hang a bag between, it'll set off the dryer.

I did notice recently that they have a sign by this changing station that there is another in the "family" restroom; I haven't been in there to investigate though.

While it's true that they are very loud, you have to be exposed to 100 dBA for 15 minutes nonstop to cause permanent hearing loss, according to NIOSH guidelines. So don't let your kids hang out for a long time around hand dryers, I guess.

Fashathus

While NIOSH guidelines recommend 15 minutes at 100 dBA the WHO has different guidelines for children which say that 100 dBA can be damaging after only 1 minute. source see chart on page 7.

GentleLion2Tigress

Source? It said in the article there is no safe amount of time for anything over 115 dBA IIRC.

Edit: I stand corrected, the article states 111 dBA for children.

“NIOSH has determined that there is no safe duration of unprotected exposure to sounds greater than 111 dBA”

tugboattommy
28
1 week ago

Source

NIOSH has a permissable noise exposure limit of 85 dBA in 8 hours with a 3 dBA exchange rate, meaning you can safely be exposed to 85 dBA for 8 hours, but for every 3 dBA the noise increases, the time allowed is halved. So 88 dBA is safe for 4 hours, 91 dBA for 2 hours, etc. That puts 100 dBA at 15 minutes of exposure. Of course, by this same method, 115 dBA is a very short amount of exposure, around 15 seconds or so, but as I mentioned in my first comment, you likely won't cause damage using a dryer at 100 dBA.

But obviously we need to quiet these down, because that's still unacceptably loud.

Edit: nose/noise typo

Fashathus
20
1 week ago

The article says that children's hearing is more sensitive than adults, the link you have is for workplace noise levels. The world health organization seems to agree that children's ears are more sensitive. On page 7 of that link you can see that they list 100 dBA as being damaging if exposed to for 1 minute. If the 3 dBA halving the time rule still holds true that means that 106 dBA, which if you look at the chart on the article you will see some have been measure at or over 106 dBA, can be damaging in 15 seconds which is a pretty reasonable amount of time for hand drying.

tugboattommy

Yep, children are more sensitive. Not sure where exactly you're seeing that 106 dBA exposure limit is 15 seconds though. Can you point me in the right direction?

According to safe work Australia, the exposure is based on an average exposure of 85dB(A) for 8 hours. So at 115dB(A) you have 28.8s of exposure before you exceed the limit.

140dB(A) is considered instantaneous damage.

GentleLion2Tigress

I would think this is for adults but the article puts 111 dBA as the threshold for children.

Something being perceived as too loud, doesn’t mean it is too loud, or that it is damaging.

What you may think is “too loud” is just what you think. The same noise at a different time, or to a different person, may be seen as acceptable. People will complain about a quiet but “harsh” noise, while happily accepting a louder but “pleasant” noise.

Perception is everything until the meters come out.

I can’t stand using them. They are loud and obnoxious, and barely work. If it’s a restaurant I take napkins with me or if it’s a rest stop with eateries, I grab napkins. You can almost always find napkins/towels where they are located if the bathroom has none.

I actually wrote a policy brief for a class of mine in my doctorate studies on this. Not only do they operate at higher Dbs than they say, but it blows germs across all surfaces in a bathroom. This could include faucet handles, door handle, soap dispensers, etc. Also, since it usually involves warm air, it harbors bacteria within its vent. They truly are gross.

Best thing to do is to automate the bathroom and use paper towels. When I say automate, I mean everything. Auto flush, auto soap dispenser, auto faucet, auto paper towel dispenser, and automatic doors. Of course this is costly, but it does save you from touching surfaces that may otherwise have tons of microscopic fecal matter. All of which could result in illness and lost time at work for employers. Add it up and it actually may save money because it’s less chance of illness

I remember talking about this in physics class years ago when measuring sound waves. Can do some heavy damage over time.

So I'm not crazy.... I have been wondering for years how these devices got approved for public use. I guess I figured it was because they typically aren't actuated for more than 10 seconds at a time. Xcelerator is LOUD AF.

I’ve never understood how people can stand the noise, it’s horrific.

Yes, yes, yes. The noise is intensified by the bathroom walls covered in tile, echo making it much worse.

I actively avoid using hand dryers unless they’re the airblade kind typically by Dyson, largely for how deafeningly loud they are. But also because a single paper towel is As bad, if not a little better than the average hand dryer. Further, according to https://www.greenschoolsalliance.org/blogs/16/394, hand dryers are definitely not eco-friendly.

Granted, according to the article, 2% of landfill contents are paper towels, and those do produce methane during decomposition. Also considering logging practices and fossil fuels to transport supplies, one single paper towel per wash still has its repercussions. But the power used to manufacture, ship, run, maintain, and eventually dispose of standard hand dryers, which will remain in landfills for far longer than paper towels, combined with that awful noise... that is enough for me to feel okay about the trade off.

If you flick each of your hands twelve times, one paper towel really is all you need. I always flick alternating in counts of eight. Not sure why, but the rhythmic pattern helps make it less monotonous.

Those of you grabbing six paper towels every time you wash up, you may as well be a smoker flicking your butt onto the ground with that nonsense.

It becomes much louder because of the acoustic of the bathrooms which are mostly much smaller than the tested environment, and cover in tiles which are not sound absorbing, which in turn, amplifies the noise.

This is kinda similar to the cars emission testing scandal. The test is done artificially but in reality it is a lot more damaging on the regular use.

My 6 year old son has sensitive ears so I have to hold his ears tight when we use a public restroom. I also have to put toilet paper on the sensor when he uses a stall so it doesn’t flush without notice.

My four year old freaks out at the sound of these. I was just thinking he had sensitive hearing. I never considered it could be even louder for him because it was closer to his ears.

this doesn't surprise me after hundreds of trips to bathrooms across the nation with our children. Those things are often brutally loud.

The ones recently installed at my university sound like airplane engines. They also gave us those huge pervert gaps in all the doors too. Ahh America.

I dried my hands in a donut shop bathroom and it was literally as loud as one of our jets starting up.

Perhaps they should be tested in room where the walls are completely tiled.

I mix at a small church and they always complain about how loud it is. Which it isn’t, I average 90 dB SPL. The problem is the people who bought the building didn’t like the look of the spray-on acoustic treatment on the upper part of the back walls and scrapped it all off. So now all the high frequencies are bouncing all over the place.

One day I was drying my hands with one of those Xlerator air dryers, and for giggles got my SPL app out and it was averaging 118 dB from a foot away.

People want to complain about my mix but don’t call up these hand dryer companies and complain about something that is actually damaging your hearing.

My son has autism and doesn't have many issues with sounds, but hand dryers man. He's ok now with world dryers, but if there is an xcelerator I have to guard him from it and unless there's no other choice he won't go in a public restroom with that brand unless no one else is in there.

My kids have a legit phobia of these dryers and everytime I take them into a public bathroom I have to reassure them that I won't use one.

It's weird that sound levels have to be explained to people. I'm the guy with ear plugs when I leafblow, lawnmow, hedgetrim or go to concerts etc.

I mean, if it annoys you, it's too loud.

I hate them. I won't use them. They hurt my ears and so do some commercial toilets.

Measuring at kids' height is an interesting piece. Would make a great example for a market research class.

I worked at a call center that employed 700 people. One bathroom sounded like a jet engine taking off and you could hear someone drying their hands in while on calls in certain areas of the building.

One of the reasons I've always hated hand dryers is because they're obnoxiously loud. Then they're placed in rooms where nothing will absorb or dampen sound and it's positively maddening.

These XLERATOR ones are ridiculously loud. It’s like they’re trying to blow the water off rather than dry it. If you actually rub your hands together and spread the moisture around, the quiet hand driers of yore work just fine. These ones actually make that technique a little more difficult.

The Dyson airblade ones are even worse, since they virtually prevent you from rubbing your hands together at all, and end up having water run down onto them and onto the floor.

Sometimes design can really miss the point!

I always wear earplugs in malls and on the street (city). The level of noise in public spaces these days is insane. And no one seems to care.

I literally have to cover my ears at work when someone hits the damn thing in the tile-and-metal bathroom. It's truly painful. I'm a driving fan and have been to many autocrosses where the allowable OSHA decibel level is 90 because of surrounding neighborhoods. The stupid thing in the bathroom is EAsily that. Plus, everyone knows at this point that they just spray germs all over the place. A truly atrocious "invention."

My kids always complain that it's too loud and we end up walking out with wet hands. I guess they're right.
