Hi Paul,
I took a generator that was supposed to be a air freshner and put it in a box along with a air pump from a fish tank and made ozonated water that way a long time ago before I knew anything about ozone. It worked too. (But soon burnt up from over use) My wife started feeling better after two weeks of this back when she had cancer. So we bought one that was made to make ozonated water and that one cured her cancer. That "better" one still wasn't a medical grade generator. But that gave rise to the motto you and I use, "Any ozone is better than no ozone".
