NWS Control Flow AIO 14x65 Sulfur Sys

The NWS Control Flow AIO 14x65 Sulfur System is the largest residential sulfur filter from Nelsen Water Treatment Solutions, designed for big homes or wells with intense hydrogen sulfide odor. Its 14" x 65" polyglass tank holds 3-1/2 cubic feet of sulfur media for maximum whole-house odor reduction — all without salt or chemicals.

Air injection oxidation powers the treatment: a maintained air pocket oxidizes dissolved hydrogen sulfide, the deep media bed captures the resulting particles, and Control Flow Technology meters backwash to actual household usage. The system regenerates only when needed, flushing sulfur to drain and renewing the air cushion automatically, with nothing to refill between cycles.

Highest Flow in the Range

The wide 14-inch diameter and tall 65-inch body deliver the strongest service flow among the residential sulfur systems, making this a fitting choice for large families, multi-bath homes, or wells with severe rotten-egg odor and heavy simultaneous demand. Installed at the point of entry, it ensures fresh, odor-free water reaches every fixture in the home. Supplied by Water Softener Plus, the unit arrives nearly complete — just add the plumbing adapters that match your connections — for powerful, chemical-free, low-maintenance sulfur control.

When planning the install, locate the system at the point of entry ahead of any softener so hydrogen sulfide is removed before it reaches other equipment or the water heater. A nearby drain handles backwash discharge, and the control head plugs into a standard outlet. Because sulfur problems can fluctuate seasonally on some wells, the scheduled backwash keeps odor control steady even as conditions change throughout the year.

Supplied and supported by Water Softener Plus, this Nelsen-built system reflects the quality and consistency homeowners and installers have come to expect from the brand, giving you confidence in a long, dependable service life treating your home's water. It is a sound, lasting choice for any household ready to put its water-quality problems behind it for good.
