Kenmore Elite 520
Score: 82/100
EcoPure EP31
Score: 75/100Rankings
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.
The EcoPure EP31 is a demand-initiated regeneration water softener designed for households of 1-4+ people, utilizing predictive technology to minimize salt and water consumption. It is NSF-certified against Standard 44 for hardness reduction and efficiency, and compatible with both municipal and private well water systems. However, its limited iron capacity and specific salt requirements may be drawbacks for some users.
