The Hard Facts on Soft Water. During the water softening process, water softening salt charges thousands of tiny resin beads inside the water softener with sodium ions. As hard water moves over the resin beads, the calcium and magnesium minerals are attracted to the beads and replaced with sodium ions, creating soft water.

Hard water or soft water? Water hardness and softness has nothing to do with its touch and feel. It is more about chemical compounds dissolved in it. They are both safe for human consumption. Pure water (like clean rainwater) is soft water.
