About ozone generators

[arundo]

I'm looking ozone generators for water in websites like ali**press. Some of them claim 10 g/h. Any of you proved it?

During the process of O3 generation, is mandatory to enter O2 from a compressed bottle to the system to bring O3/O2, or with atmospheric air N2 remains unalterable?

Thanks

any ozone generator on aliexpress (apart from industrial sized ones that cost thousands of dollars) that claim 10g/h are bullshit. at most, you'd get a few grams per hour, and that'd be when running them off pure oxygen, not air. air cause a significant amount of nitric oxide to be produced instead of ozone
