Aquasana SimplySoft
Score: 88/100Rankings

The Aquasana SimplySoft® 40,000 Grain Water Softener is a highly efficient, certified whole-house system designed for households up to five people, featuring metered regeneration to save salt and water. Its main limitation is a low iron reduction capacity (1 ppm) and lack of power backup. It is best suited for users with city or well water who prioritize efficiency and certified performance over high iron removal.

NuvoH2O is a salt-free water conditioning system that utilizes CitraCharge, a citrus-based citric acid formula, to bind hard minerals like calcium and magnesium. This process prevents scale buildup on pipes and appliances while retaining beneficial minerals in the water, offering an eco-friendly alternative to traditional ion-exchange softeners. However, it does not produce true soft water for soap lathering and requires regular cartridge replacements.
