Read MoreThe cost of a water softener primarily depends on the type of softening method it uses. The three main types of water softening methods include salt-based salt-free and magnetic water softeners. In general salt-based water softeners cost about 400 to 2700 depending on the model. Salt-free water softeners range in price from about 1300
