All things being equal, if you get the concentrations right and have an actual MIOX pen for comparison I think that's unnecessary. The process is the same, so the mixed oxidants will be the same. The only potential difference here would be the carbon electrodes vs. the platinum covered titanium. I suppose that any given water supply has plenty of dissolved minerals that could give a few unwanted byproducts. But the sheer amount of carbon could potentially give off carbon tetrachloride, which is no good for the system. One way to eliminate any risk and get the same results would be to use gold or platinum coated nodes (many home entertainment cables are so coated).

I wouldn't really want to be testing with that stuff outside of a lab's controlled conditions and to get real results, it wouldn't be cheap. I'd rather take advantage of the research already done and simply copy the system on the cheap. <img src="/images/graemlins/smile.gif" alt="" />
