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.

The AFW Filters Built Fleck 5600SXT is a comprehensive whole-house water softening system that combines 48,000-grain softening capacity with an upflow carbon filter for superior water quality. It features NSF-approved components and a digital metered valve for efficient operation. It is best suited for households seeking both soft water and filtration for chlorine and organic contaminants.
