In most households, a water softener is an essential part of the water filtering system, especially if you live in a town that has particularly hard water. A water softener removes minerals such as magnesium and calcium from the water supply in your home. This significantly improves the quality of your water and prevents many issues such as mineral buildup on faucets, showerheads, and sinks, dry skin and hair caused by hard water, the bad taste of drinking water, spots on freshly washed dishes, etc. But simply installing a water softener is not enough. You also need to properly maintain the appliance and replace its filter on time.
