A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, toxicity and dog-whistling are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !uspolitics@lemmy.world
7) No Hit-and-Run questions.
Please don't delete your post for no apparent reason. If you plan on deleting a question later, say so in the post, or if you feel that you have a good reason to remove it, message a mod beforehand. It's not fair to the ones who took their time to answer, and it's not in the spirit of the community.
8) No Bots.
Posts or comments from bots, LLM's, AIs, Neural Networks, Transformers, or Marvin the Paranoid Android are not welcome in AskLemmy. Real humans only please.
Reminder: The terms of service apply here too.

These devices produce ionized air which is indeed claimed to deactivate viruses. Unless the device is defective ozone might only be produced as a byproduct in small quantities, due to the toxicity, you've mentioned.
That might be right in general, but the device that the commenter included a picture of says オゾン (ozone) all over it. You can also see the O3 molecules in the diagram. So producing ozone does appear to be the primary function of that particular machine.

Basically, the stuff they use in shops and elevators is useless because it's too low concentration to matter. The low grade "gentle" ozone machines are just marketing scams. You're just mildly polluting the air, which if anything will make COVID worse, by mildly increasing the public's risk of respiratory disease. Ozone is a major pollutant; humans are not meant to breathe ozone at all if possible.
You have to really saturate the space with a powerful ozone generator to have any effect. But then you have to be extremely careful to give the free radicals enough time to dissipate before any humans go in there, or again you're just poisoning people.
Honestly, it's insane to me that it's even legal to routinely fill an indoor habitable room with an invisible caustic gas that has low odour. With no mandated safety precautions like a sign on the door or a lock to prevent accidental exposure. Just y'know, filling my room with gas again, no biggie.
