The hand dryers that promise you bacon are LYING BASTARDS!

Just keep your hands there long enough

You must become the bacon you wish to see in the world

Funnily, that's not really true. Such studies showing that exist but are sponsored by… paper towel companies

[–] Karjalan 36 points 4 days ago (1 children)

Fucking dystopian late stage capitalism... Every fact is not actually a fact cause it's sponsored by corporate interests

[–] [email protected] 12 points 4 days ago (1 children)

Half the words are automatically capitalized when I text. Because they're part of a corporation's name.

I tell my phone to "Remove Suggestion" on that every time, but it never fucking takes and it pisses me off. Don't capitalist twitter or god.

Yes, and the ones that show air dryers to be healthier are funded by... hand dryer manufacturers.

[–] RQG 13 points 4 days ago (4 children)

Someone should fund independent research.

[–] ZeffSyde 26 points 4 days ago

I went for a whole month drying my hands with only independent research and the results were similar to using paper towels.

I remember someone tested this, and the bacteria was found in a wider area.

Either way bacteria is everywhere and we got immune systems.

Remember kids, when making graffiti, always cite your sources.

On the bathroom stall:

Here I sit all broken hearted,

Came to shit and only farted.

Then one day, just by chance,

Tried to fart and shat my pants.

Yet, the best hand dryers are still your trousers

Zero waste and zero bacteria spread, truly perfect.

Denim is naturally anti-microbial

I particularly hate those airblade things even more than regular air dryers. I like that they're faster and typically not as gross and warm but they are designed in a way where you feed your hand in to a narrow gap with powerful air jets in front of and behind your hands in this gap. Your hands are not a completely uniform symmetrical shape, so the jets buffet your hand around and they inevitably touch the parts of the device where the jets are located, right where everyone else has had the same thing happen. It grosses me out.

[–] [email protected] 14 points 5 days ago

And also incredibly loud too.

Why are there germs on your hands right after washing them? Didn't mythbusters already test it and concluded that they are only bad when people don't really wash their hands.

[–] Bassman1805 40 points 5 days ago

Yes.

The followup question is "how many people think getting their hands wet without soap is sufficient hand-washing" and the answer is not terribly comforting.

Good time to share How to use one paper towel (to thoroughly dry your hands in a public restroom).

Shake. Fold. It really does work.

Is this true? Seriously curious.

This is not hot air though, so the cited source does not apply.

Edit: but it does link to more relevant study towards the end, comparing different means of hand drying.

[–] [email protected] 34 points 5 days ago (1 children)

You're right and I linked a fairly old study. I've edited my comment to add a more recent source.

Findings: Air bacterial counts in close proximity to hand drying were 4.5-fold higher for the jet air dryer (70.7 cfu) compared with the warm air dryer (15.7 cfu) (P=0.001), and 27-fold higher compared with use of paper towels (2.6 cfu) (P<0.001).* Airborne counts were also significantly different during use of towel drying versus warm air dryer (P=0.001). A similar pattern was seen for bacterial counts at 1m away. Visualization experiments demonstrated that the jet air dryer caused the most droplet dispersal.

It’s insane we keep using those things after covid. They’re fucking disgusting.

How can it spread germs if the germs are 99% gone after having washed your hands with soap? We're assuming people aren't washing their hands properly, right?

[–] [email protected] 30 points 4 days ago (1 children)

Yes you can assume all people don't wash their hands correctly.

[–] [email protected] 9 points 4 days ago (4 children)

Which is accurate. How often have you seen somebody spend 30 seconds washing their hands in a public restroom? For me it ain't exactly common

[–] [email protected] 5 points 3 days ago

I wash my hands for nearly a minute. But most of that time is spent trying to get those stupid no touch faucets to work.

Some microbes will survive the hand washing process, and need to be removed by drying. Those Dyson air blades collect germs from water from washed hands and the toilet environment, then blow the germs around. It's gross.

Also, Mr Dyson is a fucking dick.

I'll just leave this here:

Hygiene associated with the product has been questioned in research by the University of Westminster Trade Group, London and sponsored by the paper towel industry the European Tissue Symposium

It's ok to be cautious, but if the data is accurate then it doesn't matter much.

My biggest issue is the decibel level. I can hear, for now, but the decibel level on those things makes one of my ears feel like it’s being blasted out of my skull and induces ringing.

I use the paper because it doesn’t hurt my ear.

Yes, I’ve seen a doctor, it simply is what it is and my only recourse for that ear is to wear ear protection. In any public restroom, apparently.

My daughter is extremely noise sensitive and can't handle the noise of those either. After a really rough 2 hour drive involving 3 gas station stops because she refused to even try to use one due to the auto-flushing toilet my wife suggested "making an app to track public bathrooms with air dryers and autoflushing toilets" and I've been debating if I want to start tagging every public bathroom I visit on Open Street Map with the toilet flush mechanism and existence of air dryers. And if i did so I'd probably also mark what changing table amenities are available and if there's more/less changing table amenities in the womens' or mens' rooms.

I just wish people would know how to use paper towels so that they don't end up wasting huge piles of them for nothing. 1 sheet is enough. You don't need 5. Do it like this:

  • After washing your hands, brush excess water off each hand using your other hand. Your hands should not be dripping wet when you reach for the paper towel.
  • Take a single paper towel. Don't scrunch it up, and don't just clasp the towel. Use all parts of the paper towel to deliberately wipe your hands. The paper towels are quite absorbent. They don't need to be 100% dry to remove the water from your hands.

The end. If you do this, your hands will not be wet. You will not need a second paper towel.

[–] [email protected] 16 points 5 days ago

You missed something. You gotta fold the paper in half. The capillary action will trap more water in between the folded halves than it could unfolded.

The Shake & Fold method. There was a Ted Talk!
