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 | 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 |

The parcel-shippable CS AIO 10"x54" Katalox System packages 's Connected Series AIO™ Plus multi-contaminant filter for convenient delivery. Built around high-performance Katalox-Light® media, it targets iron, manganese, and hydrogen sulfide in a single tank, an excellent fit for well water carrying more than one nuisance problem. The parcel-ready packaging makes this capable system easier to handle and ship.
The Connected Series design connects over Bluetooth to the free Legacy View app for iPhone and Android™, simplifying setup and monitoring. Its AIO Plus valve provides independently programmable air-draw and backwash cycles, letting you refresh the air pocket daily without a separate backwash to save water, and it releases the compressed air charge slowly to protect the drain line. The 10" x 54" build includes the Connected Series Air Draw Meter Control Valve, bypass valve, black polyglass mineral tank, plus Katalox-Light® media and support bed.

Air injection delivers the oxidation that Katalox-Light® relies on to turn dissolved metals into filterable solids, eliminating the need for chlorine or potassium permanganate. The system draws a daily air pocket, oxidizes iron, manganese, and sulfur, and backwashes the bed to drain on a metered schedule for hands-off operation. Add plumbing connections separately, and choose the optional chrome tank jacket for a clean look in visible utility spaces. The result is comprehensive, chemical-free treatment in one app-controlled tank.
Multi-contaminant wells often defeat single-purpose filters, so consolidating iron, manganese, and sulfur treatment into one Katalox-Light® tank simplifies both installation and ownership. The parcel-shippable packaging makes this capable system practical to deliver anywhere, and the Legacy View app keeps programming and diagnostics within easy reach. With the daily air-draw cycle reducing backwash frequency, the unit also keeps water and operating costs down while delivering clear, odor-free water throughout the home. Consolidating treatment this way reduces the number of components that can fail or need service, making the system both simpler to live with and easier for technicians to maintain over the long run.
