AFW Filters Fleck 5600SXT
Score: 86/100Rankings

The AFW Filters Built Fleck 5600SXT is a comprehensive whole-house water softening system that combines 48,000-grain softening capacity with an upflow carbon filter for superior water quality. It features NSF-approved components and a digital metered valve for efficient operation. It is best suited for households seeking both soft water and filtration for chlorine and organic contaminants.

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.
