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 hydrogen sulfide: no rotten-egg smell
- Stops black staining on fixtures and silverware
- Daily automatic backwash keeps the bed clean
- Air injection oxidizes iron, manganese and sulfur with plain air, so no chemicals or chlorine are added

The AIO 13" x 54" Sulfur Filter System parcel-delivery edition combines top-tier sulfur-removal capacity with the convenience of carrier shipping. This large single-tank air injection oxidizing filter removes hydrogen sulfide from well water chemical-free, ending rotten-egg odor throughout high-demand homes that need the maximum treatment capacity a 13-inch tank provides for their water usage.
How the System Works
During service, the system holds an air pocket at the top of its 13" x 54" mineral tank. Water rising through this oxygen-rich zone gives up its hydrogen sulfide to oxidation, and the filter media bed captures the resulting particles. The Fleck 2510SXT control valve runs an automatic daily backwash, sending trapped sulfur to the drain and refreshing the air pocket so treatment carries on uninterrupted without chemicals or salt to monitor.

As the largest tank in the standard AIO sulfur series, this parcel-ready system suits big households or homes where pronounced sulfur odor demands maximum capacity and service flow. It installs at the point of entry on the main water line, treating every faucet at once for whole-house odor control. The parcel-ready packaging simplifies delivery and handling for many installations. With automatic daily regeneration and chemical-free operation, this AIO requires little ongoing attention, giving homeowners a dependable, high-capacity solution to sulfur-tainted well water.
Despite its size, the parcel-delivery packaging lets a standard carrier deliver this high-capacity sulfur filter to homes without freight access, expanding where it can be installed. Once in place, the 13-inch tank supplies the maximum service flow and media capacity in the standard AIO sulfur line, with the trusted Fleck 2510SXT valve automating the daily backwash. Verify your water's sulfur concentration to confirm the sizing, and you'll have a convenient, chemical-free, low-maintenance system that keeps rotten-egg odor out of your home's water. Over the long run, the chemical-free design spares you the cost and handling of sulfur-treatment chemicals altogether.
