Ozone generator

"Use only in unoccupied spaces. High concentrations may be harmful" No thanks

[Spider]

from that link's FAQs:

Exposure to high concentrations of ozone can be harmful. Please stay outside the room being treated with ozone. We include a NO ENTRY sign in the package as a gift, which can be hung outside the door.
...
Because of ozone's strong oxidability, plastics exposed to ozone can easily break down and fade.
...
Ozone can adversely affect indoor plants and damage materials like rubber, electrical wire coatings, fabrics and artwork containing susceptible dyes and pigments. Since the main reaction of ozone is strong oxidation, during the oxidation certain polymer groups may have some negative effects, such as PU plastics oxidizing and turning yellow.

Why would anybody want to use such a device, instead of simply opening the windows?
In my view, it's main purpose in in medical/surgical rooms and places that need to be sterilized for sanitary purposes, surely not for just getting rid of some smell.

Most of us Europeans still don't want air conditioning at home - heating is enough for quite a number of domestic homes (certainly different for shops and hotels). In the US, it may be standard for decades (in some regions).

Perhaps, it's the same with those air "improvers". The only thing I've seen yet are air filters for allergic sufferers.

I think that depends on the smell. The only person I know who needed an Ozone treatment was for their car to remove smoke damage from a car that had caught fire in the parking spot next to theirs, but that was a pretty extreme situation.

It helps to differentiate between a device designed to produce O3 (ozone) and one that is designed to produce charged ions. The former would be nasty, the latter quite pleasant.

It seems like the OP wasn't in need of any answer or clarification....

My intention is to get rid of possible remaining Covid 19 virus parts in my flat, so only occasional usage. Every surface shall be disinfected, so the Nord also.
