Kenmore Elite 520 Hybrid Water Softener & Whole House Filter - NSF

In this review of the Kenmore Elite 520 Hybrid Water Softener & Whole House Filtration System the bottom line is simple: it is best for households that want consistent soft water and improved taste throughout the home while avoiding frequent filter swaps. The reviewer found the integrated carbon media and softening resin combine to reduce hardness and chlorine taste and odor, and the system's IntelliSoft Technology and self-cleaning regeneration make ownership low-effort for a typical 1-4 person household.

Key Features

• Carbon Media Filter: Provides whole-home improvement in taste by reducing chlorine taste and odor so drinking and cooking water tastes cleaner.
• Hardness Reduction: Softens water up to 100 grains per gallon, which helps prevent scale buildup on fixtures and improves appliance longevity.
• Clear Water Iron Reduction: Reduces clear water iron up to about 3 ppm, helping reduce staining and improve water clarity.
• No Regular Filter Changes: The system cleans itself during regeneration, so homeowners do not need to replace filters on a schedule.
• IntelliSoft Technology: Automatically adjusts regeneration to actual water use, saving salt, water and energy compared with fixed-cycle systems.
• Advanced Display Board: Lets you monitor salt levels, flow and average daily water usage for easier maintenance planning.

Who It's For

This unit is best for single-family homes of about one to four people that want a combined softener and whole-home carbon filter without ongoing cartridge replacements. Homes with detectable chlorine taste or moderate hardness will see immediate benefits in water feel and taste.

Those who should look elsewhere include households needing specialized high-iron treatment beyond clear water iron, very large families with heavy flow demands that exceed typical residential units, or buyers seeking an ultra-durable commercial-grade tank where durability questions are a primary concern.

Pros & Cons

Pros

• Integrated softening and carbon filtration delivers softer, better-tasting water without separate devices.
• Self-cleaning regeneration removes the need for routine filter replacements, lowering maintenance hassle.
• IntelliSoft controls reduce salt and water use by matching regeneration to actual demand, saving on operating costs.

Cons

• Some users report durability concerns such as tank or lid damage, so long-term reliability may vary by installation and handling.
• Not intended for heavy industrial or very high-iron applications that need specialized treatment beyond the stated capabilities.
