NWS Control Flow AIO 10"x44" Sulf Sys

The NWS Control Flow AIO 10"x44" Sulfur System is a compact, salt-free solution for the rotten-egg odor caused by hydrogen sulfide in well water. Built by Nelsen Water Treatment Solutions, it combines air injection oxidation with metered Control Flow Technology to deliver efficient, whole-house odor reduction from a small-footprint tank that fits tight spaces.

An air pocket maintained in the polyglass tank oxidizes dissolved sulfur as water passes through, and the specialized media captures the resulting particles. With Control Flow Technology, regeneration is based on measured water usage, so the system backwashes precisely when needed rather than on a rigid timer — saving water while keeping the media fresh and the air draw effective. There are no feed pumps or chemicals to replenish.

Where It Fits

The compact 10" x 44" tank is ideal for homes with limited mechanical-room space that still need dependable sulfur control at the point of entry. Because it relies on oxidation rather than feed chemicals, there is nothing to refill and no salt to haul, which keeps ownership simple and inexpensive. Supplied by Water Softener Plus, the system arrives ready to install once you add the matching plumbing adapters, providing fresh, odor-free water to every tap with very little ongoing maintenance required.

Testing your water for hydrogen sulfide and pH before setup helps confirm that air injection is the right approach and that the system is sized correctly for your conditions. Once installed and programmed, the unit requires very little hands-on care: the air pocket renews itself with every backwash and there is nothing to refill. Over the long term, only an eventual media replacement is needed to keep odor reduction at full strength.

As part of the Water Softener Plus catalog of well-water treatment equipment, this unit is chosen and assembled to deliver consistent, real-world results, helping you protect your plumbing investment while enjoying noticeably better water at every fixture in the house.
