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

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

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

    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.

    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.

    Yet, the best hand dryers are still your trousers

    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.

    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.

    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.

    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.

    Also, how is their research any worse than the one sponsored by Dyson, who is trying to sell overpriced hand dryers.

    Anyone who has ever seen one of these more than a few weeks old knows how disgusting they get because cleaning crews were never trained to clean them. I'm assuming that isn't considered in Dyson's version of the research at all. There's one in a bathroom in my area that is covered in mold.

    This has been debunked btw. Fwiw, there is a huge behind the scenes fight between big towel and big airblow.

    I'm not kidding. But basically drying via air is much more hygienic in actuality.

    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.

    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!

    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.

    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?

    It sucks that the only device that works spreads germs. Will humanity ever find a hand drying method that not only dries hands but is also safe?
