How the media works

The secret weapon inside this system is Katalox Light oxidizing media—a powerful, high-performance filtration material specially formulated to tackle dissolved iron and manganese that cause metallic-tasting water. When the control valve injects air into the tank, iron and manganese change from dissolved forms into solid particles through oxidation. Katalox Light then filters out these oxidized particles with remarkable efficiency, removing them from your water supply before they reach your taps. This process not only erases the bitter metallic taste but also clears the water of contaminants that stain and corrode your home’s plumbing.
