@Solidrock2020 ...."
now air, oz is right that in different moisture levels equals different radicals are produced. It is also able to be manipulated with negative and positive electron charges which produce different radicals and also the gap between the streamer tips and voltage that can decide what radicals are produced. "
The documentation itself clearly states that some ozone is still being produced, no matter how much you tweak the voltage. No actual numbers of either are given in the link I've provided several times.
Let's say you are correct and the FRG can produce just hydroxyl radicals with voltage manipulation. What sold me originally was the product being unique. As hydroxyl generators already exist, like the OHair, here ...

Could you please quote from the documentation where it states it could produce just hydroxyl radicals, because I can't find it.
