Do Salt-free Water Softeners Really Work. During the ion exchange process, a polymer resin bed attracts hard water minerals and replaces them with sodium ions; Dissolved and not so dissolved minerals become attached to these beads as the water passes through the tank full of these silicon beads.
It is this removal of magnesium and calcium that defines “water softening”. Instead, no salt water systems simply alter the chemical structure of minerals through a process called descaling. This means that these filters can.
What is in your water?
This means that these filters can. These water softeners work in a different way than the traditional salt based ones. Dissolved and not so dissolved minerals become attached to these beads as the water passes through the tank full of these silicon beads. Saltless systems chemically transform the magnesium and calcium but do not capture it.
