Who uses Ozone generators for sterilization?

[vernal]

I owned one when I was growing pre-legalization to kill weed smell. Never used it for PM but the basement did smell like a rainstorm haha…and I never got PM the entire time I was using it so…a correlation is there lol. Yes I can attest it will kill car smell. Friend left there window open in summer it got rained in for a couple days…mildew smell was terrible. Ozone cleared that right up. I think you need seriously dangerous ozone concentrations before it starts actually damaging materials, far beyond safe human levels.
