Removes Salt from Softened Water – Water softeners replace hardness minerals with sodium or potassium, which can make softened water less ideal for drinking. Pairing your softener with a point-of-use reverse osmosis (RO) system removes the added salt and other dissolved solids, delivering fresh, great-tasting, low-sodium water for safe drinking and cooking.
