Difference Between Softening and Filtering

What is the difference between softening water and filtering water? 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.

Filtering water involves separating mineral particles, like manganese, iron, hydrogen sulfide or other organic matter, from pure H2O. By passing water through a “filter bed,” or “media bed,” these granular particles are trapped—and clean, purified water passes through the bed.

Softening water involves something called “ion exchange” to remove dissolved minerals—like calcium, magnesium, iron and manganese—that can’t be trapped in a filter bed. 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.

Free of contaminants and minerals, water treated with Culligan softeners or filtration systems will make an impression on you and your household, and at the work place.

Whether you use a filter or a softener depends on whether the contaminates in your water are particles or dissolved minerals. Culligan Water Filters remove the substances from your water that can cause staining, foul odors, and the need for excessive cleanup. Household chores become easier because your water is working with you, not against you.
