Yeah an ozone generator is like fumigation, you should not be around when using it.
You're probably going to end up getting used to the smell. It's likely that if you ask your neighbors, this is what they'll tell you.
Your only other option is an industrial scale carbon filter, those will be expensive. They sell them for ahem grow operations if you're wondering where to start looking.
I'll say it again for emphasis you don't want to be in the same room or building as an ozone generator. It has been linked to lung cancer
Whole family got poisoned by an ozone generator in Japan. They're everywhere for some reason over there. Horrible things. I check every hotel room now for hidden ozone.
Details? Never heard of this being so ubiquitous, apart from de-stinking smoking hotel rooms?
The incident itself was: when we entered the room it smelled kind of strange, it's hard to describe. I dismissed it as "weird hotel room smell."
After 15 minutes, my asthma started to really get bad, even when using my puffer. Like, unable to breathe bad. We all developed a severe headache and dizziness. After another 15 minutes of searching, I found this small device in the room that was running on full blast.
Translating it with my phone, it described itself as an "anti-virus cleansing tool" or something. I aired out the room immediately, but ultimately we didn't feel comfortable staying there anymore and left. Quick phone research showed you should give 2 hours minimum before letting guests into the room, let alone have it running 24/7.
They refused to give us a refund. My general experience in Japan was that people will try to "smooth over" any problems, but IMO actually poisoning your guests isn't smoothable. I got the feeling this is just kind of the way this hotel operated; which is strange because it had generally good reviews.
I called my doctor later, but he said I probably should be fine; it's comparable to having chain smoked 20 cigarettes. More of a continuous long term risk than an acute risk. Not ideal for the younger family members obviously, but you also can't change the past.
After that incident, I was paranoid and on the lookout everywhere for these machines. I noticed that most elevators had "anti virus" ozone blasted in them. Stores and shops did too. I got pretty good at detecting the smell, and would look around for a sign on the wall advertising the "anti virus" features, usually in Japanese. I tried to hold my breathe or cover my mouth to prevent symptoms.
Every hotel room and airbnb had one of these machines; sometimes gigantic cabinet sized ones. Though apart from the incident, they were all switched off and hidden in a closet, so I was mostly ok with it.
I think it's to try and combat COVID-19 or something? But they just never took them down. From my research, they're actually completely useless for this purpose, but it probably feels better than doing nothing.
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.
Ionized air immediately turns into ozone. Those oxygen ions do not like being ions and will do something about it
No.

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.
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.
I have a paper mill in my town but I've never gotten used to it. That being said, I'm not nearby and only smell it when driving by.
