I'm with you Marci. I had a molecular enhancer that gave off a huge amount of ozone that stunk up the house and that's when everyone was saying ozone causes cancer. I gave the thing away at 1/4 the price. I don't trust ozone. Isn't the ozone layer miles up in the atmosphere?
I need to see more facts that it works and that it isn't dangerous because it's not something we can tell if it's working or making things worse, like in your frig. There could be some units that cost a lot of money but don't work. You should have noticed food lasting longer.
Hv had a good point with mold. If we held it near mold for 10 seconds and saw the mold disappear then we could believe.
