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 Aquasure Harmony Series 64,000 Grain Water Softener is a salt-based ion exchange system designed for larger households with high water usage. It effectively removes calcium and magnesium to prevent scale buildup and protect appliances, featuring an automatic digital metered control head for efficient regeneration. It is best suited for larger households with 5-7 people and 4 or more bathrooms needing scale prevention.
