The "bad" about soft water is that, unless you use potassium chloride for regeneration, it has sodium in it, which is bad for people on a low sodium diet. But that is overcome with an R/O drinking water addition. If you can find any valid report that shows that an electric system softens water, and which can be verified, you may be the first one. I asked the representative for one very expensive system how its effectiveness could be tested. He said, "It couldn't. At least not without a semi trailer full of equipment."
