Household water softener can not drink out of water?
Salt type water softener is calcium and magnesium ions by nano crystal packing in water, the water and the carbonate combined with the principle of scaling to soften water, but is not the removal of contaminants from water, so drink boil.
Salt water softener is absolutely impossible, because it softens water through sodium ion exchange to soften, and softened water contains a lot of sodium ions, is absolutely not drinkable!
Look, your home is a salt water softener or a salt free water softener.
