As water flows through your pipes into your tap system, it can pick up high amounts of mineral particles such as calcium and magnesium. The more these minerals are present, the higher the water will rank on the water hardness scale. According to the U.S. Geological Survey, hard water exists in a significant portion of the United States—especially in places where mountain water runoff and aged water flow through water dispensing appliances and fixtures.

Though hard water doesn’t harm you if consumed, it does pose a nuisance to cleanliness. Depending on how hard your water is, you may notice excessive water spots and residue on your glassware and dishes, dryness of hair and skin, and the breakdown of your appliances from residue buildup. This inconvenience leads to overabundant purchases of cleaning supplies and additional money spent on fixing broken faucets and appliances.

On the other hand, real soft water, at less than 1 grain hard, is free of harsh minerals. The minerals can be filtered out through a water softener system and provide a variety of benefits to you and your home. You’ll no longer experience buildup (or as much) in your pipes and appliances, your soaps will be more effective, and your skin will not feel as dry as it once did upon bathing.
