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

The NWS Control Flow AIO 13"x54" Iron System is a large-capacity, salt-free iron filter from , built for homes with heavy iron staining or high water demand. Its 13" x 54" polyglass tank holds 2 cubic feet of iron-reduction media for powerful, dependable whole-house treatment of iron-laden well water.
Treatment is entirely chemical-free, relying on air injection oxidation. An air pocket maintained in the tank converts dissolved iron into filterable particles, the media bed captures them, and Control Flow Technology meters backwash to actual household usage — flushing iron and renewing the air supply only when the household has used enough water to warrant it. There is no salt or chemical feed to manage.

High-Demand Performance
The 13-inch diameter delivers strong service flow rates, making this system ideal for larger households or wells with significant iron problems and several fixtures in use at once. Installed at the point of entry, it shields plumbing, water heaters, fixtures, and laundry from the rust-colored buildup and staining that untreated iron causes. Metered regeneration keeps water use efficient over the long term. Supplied by Water Softener Plus, the unit arrives nearly complete — just add the plumbing adapters that fit your connections — for dependable, salt-free, low-maintenance iron control.
For best results, plan the installation near the point where water enters the home, ahead of any softener or under-sink filtration, so iron is removed before it can foul downstream equipment. A nearby drain is needed to carry away backwash water, and a standard electrical outlet powers the control head. Once commissioned, the system runs on its own schedule, and a quick periodic glance at the valve display is typically all the attention it requires from the homeowner.
From the control valve to the media bed, every part of this Water Softener Plus system is selected to work together reliably, so once it is installed and dialed in you can simply enjoy the improvement in your water without thinking about it.
