Saltless Water Softeners vs. Salt Based Water Softeners. As discussed above, salt-based water softeners use a negatively charged resin bed to attract and remove magnesium and calcium from the water supply. These water softeners also use salt to clean the water softener and regenerate the resin bed. During regeneration, positively charged sodium ions replace the hard water minerals trapped in the resin bed, and the hard water concentrate is flushed down the drain. Salt-free water softeners, on the other hand, do not remove hard water minerals from the water. Rather, they transform the magnesium and calcium chemically, so that they do not cling to surfaces and precipitate into scale.
