GE FQK2J

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.
