Thanks for reply but yeah we are in agreement. That's why I quit using it like 2 decades ago. If it can destroy organic matter that obviously includes ours.
I was just curious on the quantity thing. A general air blown ozone generator will not hurt if at low power. It obviously won't provide any benefits either. But for water it's useful so was curious if you knew something i didn't.
On topic - a powerful UV lamp (not something you'd want to hit your eyes) in your central AC is still very useful. Airborne stuff, mold spores, etc. at a minimum it keeps the coils clean.
