Water described as “hard” contains high amounts of dissolved calcium and magnesium. Hard water is not a health risk but is a nuisance because of mineral buildup on plumbing fixtures’ and poor soap and or detergent performance. When hard water is heated or evaporates, limescale deposits or thin layer of limescale are created so straining is a must.

Hard water and limescale also bring many inconveniences to daily life. For instance, it is difficult to descale some affected taps, pipes and water heating appliances. Furthermore, hard water also affects your wallet. You need to buy more washing powder, special descaling products and replace damaged appliances. Your energy bill will be higher too. All of this naturally has an impact on the environment – residues of cleaning products end up in drainage water, the mountain of dumped appliances gets higher and fossil fuels become increasingly depleted.

This video shows how ITO-CAL, a water softener series from IITOYA, is able to reduce water hardness just by passing the water through the filter.
