A water softener is a whole-house filtration system that removes hardness-causing calcium and magnesium minerals from your water through a process called ion exchange. A water softener addresses one of the most prevalent and devastating water problems: hard water. Hard water wreaks havoc on the modern home.

A water softener works to treat hard water by removing the minerals responsible through a process called ion-exchange. Mineral ions that cause hardness and damage to your home are trapped by resin within the system and exchanged for sodium and potassium ions.
