C-Series AIO Katalox Filter

A complete whole-house air-injection filter. One price includes everything listed below.

What's in the box

• Control valve: Connected Series air-draw metered valve with Bluetooth app with built-in air injection.
• Bypass: bypass valve (included).
• Mineral tank: black fiberglass-wrapped mineral tank with support bed and distributor.
• Media: Katalox Light catalytic filter media, sized to the tank.
• Also included: 1" plumbing adapters, install and service manuals.
• Ships pre-built, ready to install, free in the US.

How it works

The valve draws a pocket of air into the top of the tank. Water passes through the air, which oxidizes iron, manganese and hydrogen sulfide into particles, and the media bed filters them out. Every day the valve backwashes the bed, sends the trapped particles to drain and refreshes the air pocket.

Media benefits

• Removes iron, manganese and hydrogen sulfide (rotten-egg smell) in one tank
• Handles high flow rates in a compact tank
• Long media life
• Backwashes the trapped particles to drain automatically
• Air injection oxidizes iron, manganese and sulfur with plain air, so no chemicals or chlorine are added

The CS AIO 10"x54" Katalox System combines 's Connected Series AIO™ Plus air-injection control with premium Katalox-Light® media for multi-contaminant well-water treatment. Katalox-Light® is a catalytic media effective on iron, manganese, and hydrogen sulfide, making this a strong choice when water carries more than one nuisance contaminant and a single dedicated filter will not cut it.

Smart Bluetooth connectivity through the free Legacy View app lets you program and monitor the system from an iPhone or Android™ device. The AIO Plus valve features independently programmable air-draw and backwash cycles, so the air pocket can be replenished daily without an extra backwash, saving thousands of gallons of water per year, while a slow release of the air charge before backwash protects the drain line. The 10" x 54" configuration includes the Connected Series Air Draw Meter Control Valve, bypass valve, black polyglass mineral tank, plus Katalox-Light® media and support bed.

• 10" x 54" black polyglass mineral tank
• Katalox-Light® catalytic media for iron, manganese, and sulfur
• Connected Series Air Draw Meter Control Valve with Bluetooth
• Free Legacy View app for iPhone and Android™
• Programmable air-draw and backwash, gentle air release
• Shipping weight: approximately 166.93 lbs

Air injection supplies the oxidation that Katalox-Light® uses to convert dissolved metals into filterable particles, all without potassium permanganate or chlorine. This makes the system ideal for homes facing combined iron and manganese staining along with sulfur odor in one tank. Each cycle draws a daily air pocket, oxidizes the contaminants, and backwashes the bed to drain automatically. Choose plumbing connections separately, and add the optional chrome tank jacket for a finished appearance in visible spaces.

Katalox-Light® is a premium catalytic media valued for tackling several contaminants at once, which makes this configuration especially efficient for wells that suffer from iron, manganese, and sulfur simultaneously. Rather than installing two or three separate filters in series, the homeowner gets comprehensive treatment from one smart tank. The Connected Series app and daily air-draw cycle round out the package with convenient monitoring and meaningful water savings over conventional backwash-to-recharge designs. By handling several contaminants in a single backwashing tank, the system also saves valuable floor space in the utility area compared with a multi-filter train.
