Tapwater comes with varying amounts of calcium and magnesium, which I think are the major components of general hardness for most of us. RO/DI filters will remove these components, as do the whole-house filter that consume salt. The whole-house filters actually replace the calcium and magnesium with sodium, which causes fewer problems, in general. I recommend using RO/DI water in most every situation.
