Aquasana SimplySoft
Score: 88/100Rankings
The Pentair 64k Fleck 5600SXT is a robust whole-home water softener designed for larger households with high water consumption. It features a high-capacity resin tank and a reliable digital metered valve that optimizes regeneration based on actual usage. While it requires significant space and a 24V power source, its durability and efficiency make it a top choice for demanding applications.
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.
