NuvoH2O Home Duo system maintains the healthy 'hard' minerals in your water. Instead of removing and replacing hard water minerals, including Calcium and Magnesium, with sodium or potassium like old-fashion softeners do, our Home Due system uses a citrus-based softening formula, CitraCharge®, which bonds to these minerals making them incapable of sticking to pipes and surfaces.
