If you use an OZONE generator, please read this:
Ozone in Buildings
There are similar warning from OSHA, EPA and other government and watchdog agencies. Christ, even grow shops warn you about using ozone correctly - you'd think RIU would do the same.
They are not safe unless you use them properly. Do not, i repeat, do not attempt to build your own ozone generator. They can do a hell of a lot more than damage rubber and anyone working with them should know that.
Either drop the coin on a carbon filter or UL approved ozone generator (and follow the directions) or pull the plants/live with the smell.
