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

Efficient Iron Removal
The system relies on air injection oxidation rather than chemicals. An air pocket in the tank oxidizes dissolved iron into a solid form, the media bed filters it out, and Control Flow Technology meters backwash to real household water use — conserving water while keeping the bed clean and active. There is no salt to haul and no feed chemicals to replenish, which keeps ownership both simple and affordable over time.
The generous 12-inch diameter boosts service flow and treatment capacity, making this a fitting choice for larger homes or wells with heavy iron content. Installed at the point of entry, it protects appliances, plumbing, and fixtures from staining and buildup throughout the home. Supplied by Water Softener Plus, it ships nearly complete; simply add the plumbing adapters that fit your setup for a clean install and reliable, low-maintenance iron control delivered conveniently by parcel.
Before installation, it is worth testing your water to confirm iron concentration and pH, since air injection performs best within typical residential ranges. Position the unit on a level surface near your main supply line and a suitable drain, and allow clearance above the tank so the control valve can be serviced. Many installers pair an AIO iron filter with a downstream sediment filter or softener for the most polished result, and this platform integrates easily into such a treatment train.
Whether you are upgrading aging equipment or treating a new well for the first time, this system from Water Softener Plus offers a proven, low-fuss path to cleaner water, backed by the trusted engineering behind every component in the package.
