CS AIO 13"x54" Katalox System

The CS AIO 13"x54" Katalox System is a high-capacity, multi-contaminant filter from Nelsen's Connected Series AIO™ Plus line, rated at 80,000 grains. By combining air injection with premium Katalox-Light® media, it targets iron, manganese, and hydrogen sulfide together, making it a powerful all-in-one solution for challenging well water in larger homes.

The metered Connected Series valve pairs over Bluetooth with the free Legacy View app for iPhone and Android™, so you can program and monitor the system from your phone. Its AIO Plus design provides independently programmable air-draw and backwash cycles, letting you refresh the air pocket daily without an extra backwash to save thousands of gallons of water annually, and it releases the air charge slowly to protect the drain line. The system includes the Connected Series Air Draw Meter Control Valve, bypass valve, black polyglass mineral tank, plus Katalox-Light® media and support bed.

Air injection supplies the oxidation Katalox-Light® needs to convert dissolved metals into filterable solids, eliminating the need for chlorine or potassium permanganate. This high-capacity build is ideal for larger homes battling combined iron and manganese staining along with sulfur odor in a single tank. The metered valve draws a daily air pocket, oxidizes the contaminants, and backwashes the bed to drain as water use requires. Choose plumbing connections separately, and add the optional chrome tank jacket for a polished appearance.

Rated at 80,000 grains, this high-capacity Katalox-Light® system is built for larger homes whose wells combine iron, manganese, and sulfur in challenging amounts. Consolidating that treatment into one deep-bed tank simplifies both the installation and the homeowner's experience compared with chaining multiple single-purpose filters. The metered Connected Series valve, daily air-draw cycle, and Legacy View app together deliver comprehensive, chemical-free treatment with the efficiency and remote control that modern households expect. Consolidating iron, manganese, and sulfur treatment into one high-capacity tank also keeps the mechanical room uncluttered and the homeowner's maintenance routine simple.
