Just some info about the different kinds of ozon creation.

There seems to be some questions about the plasma and corona methods.

Heres some explaining:

Cold plasma: You don't see a lot of cold plasma ozone generators on the market for ozone therapy because they produce very little ozone in comparison to a corona discharge ozone generator and you cannot adjust the strength of the ozone. Adjustable ozone strength is crucial when performing ozone therapy.

Corona discharge: Corona discharge is the most commonly used ozone production method for therapeutic purposes. With corona ozone generators you are able to adjust the frequency of the ozone. This means if you are looking for desired ozone strength at a precise flow rate chances are you will probably get what you are looking for.

Cold corona discharge: Corona discharge ozone generators have come a long way. They have become more efficient and when properly engineered produce virtually no heat. Also known as cold ozone production or cold spark technology, cold corona discharge is what the most modern generators use.
