Minerals in water are what makes certain water considered “hard.” Calcium and magnesium are the most common minerals found in water.
Water quality differs depending on where you live and whether you’re getting water from a municipality or a private well.
Water softeners use a process called ion exchange to remove minerals, replacing them with sodium ions. Soft water requires less soap for the same cleaning effort, and extends the lifetime of plumbing by reducing scale build-up in pipes and fittings.
