Kenmore Elite 520
Score: 82/100Rankings
The Kenmore Elite 520 is a versatile 2-in-1 hybrid system that combines 31,000-grain softening with carbon filtration, offering NSF certification and self-cleaning capabilities. Its primary trade-off is a lower grain capacity compared to dedicated softeners and higher water usage per regeneration. It is best suited for households seeking a single unit for both softening and filtration without the hassle of filter replacements.
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.
