🌊 Product Overview
The LiquaGen 4.5” x 10” GAC + KDF-55 + KDF-85 + Cation Resin Filter Cartridge (Chlorine & Iron Reduction) is a multi-media Big Blue cartridge designed to tackle a wide range of contaminants in household water. Combining Granular Activated Carbon (GAC), KDF 55, KDF 85, and Cation Resin, it effectively reduces chlorine, iron, hydrogen sulfide, heavy metals, hardness minerals, unpleasant odors, and bad taste.
With its Big Blue 10” format, this cartridge provides larger media volume, higher flow rates, and longer service life compared to slimline cartridges—making it ideal for whole-house filtration or point-of-entry water treatment systems.
