Kenmore 350
Score: 72/100Rankings

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.

NuvoH2O is a salt-free water conditioning system that utilizes CitraCharge, a citrus-based citric acid formula, to bind hard minerals like calcium and magnesium. This process prevents scale buildup on pipes and appliances while retaining beneficial minerals in the water, offering an eco-friendly alternative to traditional ion-exchange softeners. However, it does not produce true soft water for soap lathering and requires regular cartridge replacements.
