Score: 78/100Rankings
The Brondell RF-20 is a three-stage sediment and carbon block filter replacement pack designed exclusively for the Brondell Circle RO system. It offers comprehensive contaminant reduction with multiple NSF certifications but requires frequent bi-annual replacements. It is best suited for households with existing Brondell Circle systems needing regular maintenance.
The GE FQK2J is a high-performance dual-flow replacement filter certified to reduce lead, mercury, and pharmaceuticals. Its low capacity (300 gallons) is a notable drawback, requiring frequent replacements. It is best suited for households with existing compatible GE refrigerator systems seeking advanced contaminant reduction.
