Score: 72/100Rankings

The DuraWater Fleck 5600 SXT is a whole-house water softener featuring a 48,000-grain capacity resin tank and the industry-standard Fleck 5600 control valve. It utilizes meter-based regeneration to adjust cleaning cycles based on actual water usage, offering improved efficiency over traditional time-based systems. It is best suited for whole-house applications requiring comprehensive hard water treatment with a focus on reliability and efficiency.

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.
