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 Kenmore 350 is a compact, whole-home water softener designed for households of 1-4 people, featuring IntelliSoft technology to optimize salt and water usage. It offers a high-flow valve and NSF certification, making it suitable for moderate hardness levels. However, its limited grain capacity and iron reduction capabilities make it less ideal for larger families or homes with very hard water.
