Water Conditioner aka Anti Scale
My concern on these things are not so much, weather they work or not as so much health and safety.
Every places that sells a conditioner sells the media under their own Brandname ie Softsofb, OneFlow, MEP and they don't tell you what the drinking water actually touches. Is this stuff safe long term? The only brand that has been threw vigorous testing is the Watts One Flow. When a guy from US Water was trying to tell me their MEP is certified, they won't show me the certification. It all seems too shady.
What do you think, Safe or Not Safe?
