You don’t need to be a water expert to understand the basic principles between water filtration and water softening. The following is an abbreviated version of what happens when you filter or soften your water.

I.O. is a process by which water molecules are forced under pressure through a semi-permeable membrane. The membrane of a Culligan® Reverse Osmosis System filters out impurities smaller than one micron. Reverse osmosis systems are used to filter water in a variety of locations, including homes, commercial enterprises such as restaurants, hotels, breweries, car washes, and even space shuttles!
