🌊 Product Overview

The LiquaGen 2.5” x 20” GAC/UDF + Phosphate Crystals Filter Cartridge is a dual-stage cartridge that combines Granular Activated Carbon (GAC/UDF) for chlorine, taste, and odor reduction with phosphate crystals to minimize scale buildup and corrosion.

With its 2.5" x 20” slimline design, this refillable cartridge provides longer life, greater capacity, and improved water flow compared to standard 10” cartridges. Compatible with all 2.5” x 20” slim housings, it’s the perfect add-on for reverse osmosis systems, under-sink setups, and light whole-house applications where both water quality and scale protection matter.


✨ Key Benefits & Features

  • 💧 Dual Action Filtration – GAC/UDF removes chlorine, bad taste, and odors, while phosphate crystals prevent scale and corrosion.

  • 🛡️ Scale & Corrosion Control – Protects plumbing, pipes, and heating systems by forming a protective barrier.

  • 🚿 Extended Capacity – Longer cartridge means fewer replacements and better performance over time.

  • 🔧 Universal Slim Fit – Designed for all 2.5” x 20” slimline housings.

  • 🏠 Appliance Protection – Extends the life of dishwashers, coffee makers, heaters, and other water-using appliances.

  • ♻️ Easy Maintenance – Drop-in replacement, recommended change every 4–6 months.
