Salt-based water softeners remove hardness minerals from water, specifically calcium and magnesium, therefore reducing the hardness of the water.
Salt-free water softeners, on the other hand, neutralize these minerals instead of removing them. Although these minerals are retained in the water, since they have been neutralized, they are converted to a crystallized form and aren’t able to adhere to surfaces like pipes or dishes. Leaving these minerals in your water is beneficial, since calcium and magnesium can have health benefits.
