Who says water electrolyzer is a scam. Electrolysis produces acidic oxidation potential water, in line with the relevant standards, is the sanitation commission approved disinfectant. The alkaline water that can be produced by electrolysis is an adjunctive therapeutic device if it is approved as a Class II medical device, which is not a scam at all.
The deception is obviously not any approval, or only water-related approvals, but publicize his equipment can have such and such a function, this is a deception.
