It works against you in most indoor uses, such as bathing, washing dishes, and shaving. It can clog plumbing in appliances, cutting down on efficiency and hiking up energy and maintenance bills.

You don't have to be a hydrologist to understand the basic principles behind water filtration and water softening. Here's an abridged version of what happens when you filter or soften water.
Softeners use fresh resin beads with sodium attached to the resin.
As water enters the tank, dissolved calcium and magnesium are attracted to the resin. The resin passes up the sodium in exchange for the dissolved chemicals and the water is then rid of these impurities. Whether you use a filter or a softener depends on whether the contaminates in your water are particles or dissolved minerals. To find out what's ailing your water, contact your local Culligan dealer for a free water analysis, or try our water test kit . Treated water that removes harmful contaminates is nothing but good for you and your body.
