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 dissolved iron: clear water with no orange or brown stains
- Protects fixtures, laundry, water heaters and appliances
- Daily automatic backwash sends the trapped iron to drain
- Air injection oxidizes iron, manganese and sulfur with plain air, so no chemicals or chlorine are added

This CS AIO 12"x52" Iron System is the parcel-shippable version of 's larger Connected Series AIO™ Plus iron filter, sized for homes with higher demand or stronger iron in the well water. The 12" x 52" tank delivers added capacity, and the package is prepared for convenient parcel truck delivery, sparing you the hassle of freight handling.
The system pairs over Bluetooth with the free Legacy View app for iPhone and Android™, so programming and monitoring are simple. Its AIO Plus valve features independently programmable air-draw and backwash cycles, letting you draw a fresh air pocket daily without a separate backwash to save water, while the air charge is released slowly to protect the drain line from the surge common on older systems. Included are the Connected Series Air Draw Meter Control Valve, bypass valve, black polyglass mineral tank, and the iron-reduction media and support bed.

- Bluetooth Connected Series valve with Legacy View app
- Programmable air-draw and backwash conserve water
- Gentle air-charge release protects the drain line
- Includes media, support bed, and bypass valve

Air injection oxidizes dissolved iron so it can be filtered and rinsed away, ending rust stains on fixtures and laundry without chemical feed. The larger tank handles bigger homes and heavier iron, while the parcel-ready packaging eases handling and delivery. In service the valve draws a daily air pocket, oxidizes incoming iron, and backwashes the bed to drain on a metered schedule. Add plumbing connections separately, and an optional chrome tank jacket is available for visible installations.
This parcel-ready 12" x 52" iron filter gives bigger homes ample capacity while sidestepping the logistics of freight delivery. The metered valve ties regeneration to real water consumption, and the daily air-draw option keeps oxidation strong between backwashes to conserve water. Through the Legacy View app, the homeowner can monitor status and fine-tune settings without a service call, making this a convenient, efficient choice for households that demand more iron-removal capacity from a smart system. The combination of generous capacity, smart controls, and convenient shipping makes this an excellent fit for growing families whose water demand has outpaced a smaller filter.
