Our house came with a ridiculous reverse osmosis filter on the kitchen sink, and the included TDS meter showed < 5 ppm. It seemed great at first, but we grew concerned about the potential for mineral deficit for our kids, so I disconnected it. But, we could find no definitive source of info on this topic. It's hard to take the water fanatics seriously: the manual talks about how the filter "reprograms" the water so that "the water is imprinted with the far-infrared frequencies." And: "the water molecules are shaken by the special field in a way that, for a short time, the clusters and the hydrogen bridges are broken up", and "the water is carried forward in an s-pattern movement, identical to that of water in nature". Then again, I'm the guy who disconnected it out of possibly baseless fear of demineralization, so I'm not in a position to throw stones.
