Re: Cold Plasma vs Cold Corona - from Dr. Saul Pressman

Hi Rog,

Thank you for your input. From what you described, the high pitch noise that the EXT120 makes appears to be quite annoying. How bad is it really? If I use the unit to produce ozonated olive oil 24 hr a day, this could be a problem, since I live in a small apartment unit.

How is the overall construction of the unit? I was told that the "cold corona" that the EXT120 uses is not really "cold"; it still requires a fan to cool it down. Is that true?

Thank you very much Rog. Tweet
