🌊 Product Overview

The LiquaGen 4.5” x 10” Cation Resin Filter Cartridge is a high-capacity water softening solution designed for whole-house use. Made with premium 10% cross-link strong acid cation exchange resin, this refillable cartridge effectively removes hardness minerals like calcium and magnesium—the main culprits behind scale buildup.

By exchanging these hardness ions with sodium (Na⁺) or hydrogen (H⁺), this cartridge delivers softer water throughout your home, helping to protect plumbing, fixtures, and water-using appliances from limescale and mineral damage. Built for Big Blue 10” housings, it’s perfect for households struggling with hard water.
