A.K.A 'Snot Cannon' I can see this has having the similar type of negative public health impact as the Dyson Blade dryers in public toilets, simply circulating fecal matter further in an enclosed space. Naomi Wu with the critique: https://twitter.com/RealSexyCyborg/status/150912514143903334...

This just sounds extremely manipulative and I don't see how I can trust this opinion. It also seems wrong: the average person expels 300-500ml of this fluid a day in the form of a fine mist- an aerosol. You can see it in cold weather. That's condensation from humidity in the air you breathed out. That's why you can only see it in cold weather. Does it really contain viruses? Any data on this?

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

Bacteria -> Your hands Your hands -> Windstream Windstream -> Goes everywhere It's not even about Dyson dryers, but dryers in general

It's meant for hands that were just washed. I understand that not everyone does a great job washing, but I have a hard time believing this poses a real threat..

Let's look at some studies:

> Participants washed their gloved hands with a suspension of MS2 bacteriophage and hands were dried with one of the three hand-drying devices. [...] Over a height range of 0·15–1·65 m, the JAD [jet air dryer] dispersed an average of >60 and >1300-fold more plaque-forming units (PFU) compared to the WAD [warm air dryer] and PT [paper towels] (P Okay, but I'm sure just-washed hands aren't all that dirty, right?

> This observational study was conducted to evaluate [...] hand hygiene practices among college students. [...] Overall, 72.9% of students washed their hands, 58.3% practiced hand hygiene (using either soap or hand sanitizer), and 26.1% washed their hands adequately.[2]

I couldn't find any epidemiological studies, but this feels like good enough of a reason to stick to other options considering these things are a solution in search of a problem anyway.

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.

I think the target market is less “COVID” and more “Beijing air pollution”.

Or smoke season sort of anywhere downwind from the west coast of North America.

Respirator masks work much better though and are cheap. I put on my woodworking N99 respirator and it works perfectly for wildfire smoke. This is about the size of a Covid N95 mask

100%, and even aside from cost I personally don't want another thing with batteries to manage. Elastomeric respirators can be even more comfortable with a better seal, and cheaper over repeated wear. Probably what I'll do if I need to be outdoors in heavy smoke again this year.

> Respirator masks work much better

I haven’t observed this to be true; I generally find them to be very uncomfortable. Do you have a brand recommendation?

I also have a pretty big beard which makes them less effective.

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.

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.

I legitimately can’t tell if this is a joke or not. It must be a joke, and yet it seems legit.

The function combination is too dystopian. The more I think about it, the more bizarre "luxury headphones with noise cancellation and air purification" seems.
