• Control valve: Fleck 2510SXT air-injection valve with built-in air injection.
• Bypass: 3/4" 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

Why this system costs what it does

	This system	Typical lower-priced kits
Iron and sulfur treatment	Air injection: oxidizes with plain air, no chemicals	Often chlorine or permanganate feed, or no oxidation step
Filter design	Automatic daily backwash keeps the media bed clean	Often a non-backwashing upflow head or a cartridge housing
Bypass valve	3/4" bypass included	Often not included or an extra option
Media	Named media, sized to the tank	Media type or amount often not stated
Delivery	Ships pre-built, ready to install	Often ships in pieces for you to assemble and load
Shipping	Free in the US	Free only above a minimum, or extra

Ships preloaded and ready to install. The Katalox-Light media is already loaded in the tank and the control valve is mounted and set up at the factory, so there is no media to pour. Set it in place, connect it to your plumbing and plug it in.

Multi-contaminant well-water filtration with Katalox Light media

Some wells carry a combination of iron, manganese, and sulfur at once — and that is exactly what the AIO Katalox Filter is built to handle. It pairs air-injection oxidation with Katalox Light, a high-performance catalytic filter media, to tackle several nuisance contaminants in a single tank without any chemicals.

The problems it targets

Iron leaves orange rust stains; manganese leaves darker brown-to-black staining and a bitter taste; hydrogen sulfide brings the rotten-egg odor. Many wells suffer from two or three of these together, which is where a single-purpose filter falls short. Katalox Light is chosen precisely because it addresses this cluster of contaminants at once.

Air injection plus a catalytic media

As water enters, it passes through a pocket of air held in the top of the vessel, where dissolved iron, manganese, and hydrogen sulfide are oxidized. The Katalox Light bed then does double duty: its catalytic surface helps drive that oxidation along while the bed physically filters the particles out. The result is clear, odor-free water and reliable removal of the metals that stain fixtures and darken laundry. A scheduled backwash flushes the captured contaminants and renews the air pocket automatically.

Why owners choose Katalox Light

• Handles more than one problem — iron, manganese, and sulfur — in one system.
• Robust catalytic media that supports strong oxidation and filtration performance.
• Chemical-free operation with automatic backwash renewal.
• Single-vessel design for a compact, easier install.

Because well chemistry varies, correct sizing and, where needed, staging with a neutralizer or softener make all the difference in long-term results. The system installs on the main line ahead of the water heater and needs a drain for backwash. Send us your water test and flow requirements and we will confirm the right build. Ships free in the US with manuals and expert setup help.

Confirm your configuration

Because this filter can address iron, manganese, and sulfur together, the ideal media depth and backwash schedule depend on how much of each your well carries. A current water analysis lets us verify Katalox Light is the right choice and tune the setup, and our team stays available afterward to help you keep it performing at its best.
