🌊 Product Overview

The LiquaGen 4.5” x 10” Birm / KDF85 Filter Cartridge is a Big Blue refillable cartridge designed to reduce iron, manganese, and hydrogen sulfide (rotten egg smell) in residential and light commercial water systems. By combining Birm media and KDF85 granules, this cartridge provides powerful dual-stage filtration that protects your plumbing, fixtures, and appliances from staining, odors, and metallic taste.

Engineered for Big Blue 4.5" x 10” housings, this cartridge is ideal for households that experience low to moderate levels of iron or hydrogen sulfide (<5 ppm) and need a higher flow rate and capacity than slimline cartridges can provide.
