Ok here's a technical breakdown of why the “@[email protected] Zone™ Air-Purifying Headphones” aka. the Snot Cannon aka. the Wearable SuperSpreader Event is such a staggeringly bad idea and a significant danger to public health if it is allowed to be sold.

In honor of @[email protected] actually trying to launch this monstrosity and tech media being too timid and worried about losing Dyson ad money to actually do anything but publish their press release, it's time for a bump-

In case you think @[email protected] are a bunch of really smart people who totally know what they are doing and are on top of all this, here was their rebuttal:

(Shout out to @[email protected] for not crediting me with raising the issue- you're in good company)
I asked a Dyson Zone engineer about protection against covid. Here's what he said…

It's been claimed wearing a Zone could increase the risk of infection but Dyson is adamant this is not the case

So:
1. Powerful enough to push air away from your face, but also not powerful enough to push air away from your face.
Show threadNaomi WuDec 8, 2022
2. Yes? You are exhaling the same quantity of virus-carrying particles, but since (as you say) they are less concentrated, that means you are defusing them over a wider area. That's why we're calling it the Snot Cannon.

3. COVID is airborne. Physical barriers like face shields that don't stop aerosols provide almost no protection. Droplet theory is dead, and there's no going back. That means no walking around in Aum Shinrikyo/Rajneeshee headgear blowing deadly respiratory viruses on people.

But it sounds like they have a really powerful, battery-powered HEPA filter, which is something Dyson knows about and is good at, and is also something great that people really want to protect themselves, why not just- not, point it at their faces?

Stuff that Dyson's patent portfolio would be awesome for:
Battery-powered portable HEPA
High-volume, low-noise HEPA filtration for classrooms- a commercial CR-Box but quiet.
Smaller, quieter, more ergonomic PAPRs for the immune-compromised and HCW.
- would all sell like hotcakes.

@SexyCyborg Dysan was one of the worst home HEPA filtration systems in lab tests, and by far the worst flow rate per dollar.

Look to Honeywell or BlueAir instead.

@SexyCyborg
So, lemme see if I have this straight:
They want to charge $900+ US dollars for something that doesn’t filter exhaust so that I can spray infection all over the place while wearing something that “golly we don’t know if it protects against, say COVID”
Because yea, pollution is totally why people would be willing to pay almost a grand for a face mask.

Bearing in mind that Mastodon has no text search function and assuming that you'd like people to see this, I might suggest curating it with the following:

Thankyou for keeping us up to date on Mastodon. Very much appreciated! If this curation is annoying, let me know and I'll delete!

@SexyCyborg wasn't there a super spreader event when an asymptomatic person wore one of those inflatable dino costumes in a hospital. Don't see how this thing is much different.
Show threadEmily SDec 8, 2022

@SexyCyborg ah it probably wasn't a dinosaur costume but still, not like there isn't plenty of evidence this is a terrible idea

Costume May Have Contributed To An Outbreak At California Hospital, Infecting 44

Hospital officials in San Jose are investigating whether an inflatable costume contributed to an emergency department outbreak. One hospital employee died after testing positive for the coronavirus.

@SexyCyborg are they trying to push the #SnotCannon headsets again? I thought they got completely wrecked by the FDA for fraudulent claims a year ago.

@SexyCyborg How can anyone look at this and think it's a good idea?! 🤦
It's also ridiculous what hoops people are apparently willing to jump through just to avoid putting a mask on. 🙄
(Yes, most masks aren't good for people who are hard of hearing or rely on lip reading for other reasons, but neither is this.)
