The Kenmore Elite 520 Hybrid System delivers the best of both worlds—softened and filtered water from one space-saving unit. With a 31,000-grain capacity, it reduces hardness up to 100 gpg and clear water iron up to 3 ppm, while its built-in carbon media filter tackles chlorine taste and odor for fresher, better-tasting water. NSF certified, the system also reduces barium and radium for added peace of mind. Unlike traditional filters, the carbon media is self-cleaning, so there are no replacement cartridges to buy or change. IntelliSoft Technology adapts to your household’s usage, conserving salt and water while ensuring a steady supply of soft water. Compact yet powerful, the Elite 520 fits in tight spaces and uses a 1? high-flow valve to keep water pressure strong throughout your home. Backed by Kenmore’s trusted warranty with up to 5 years of full coverage available, it’s the complete whole-home solution for healthier water, softer skin and hair, and longer-lasting appliances.
