NWS Control Flow AIO 13x54 Sulfur Sys

The NWS Control Flow AIO 13x54 Sulfur System provides large-capacity hydrogen sulfide control for high-demand households. Engineered by Nelsen Water Treatment Solutions, it uses air injection oxidation and metered Control Flow Technology to drive rotten-egg odor out of well water — entirely without salt or chemical feed of any kind.

With 2 cubic feet of sulfur media in a 13" x 54" polyglass tank, this is one of the most capable residential sulfur filters in the lineup. The air pocket oxidizes dissolved hydrogen sulfide, the media bed traps the resulting particles, and the NWS metered control backwashes based on real water usage rather than a timer, keeping both odor control and water efficiency consistently high over time.

• 13" x 54" black polyglass mineral tank
• 1" NWS metered control valve with Control Flow Technology
• Bypass valve included; plumbing adapters separate

For High-Demand Homes

The 13-inch diameter delivers strong service flow within this sulfur range, making it ideal for large families or wells with intense rotten-egg odor and multiple fixtures in use at once. Installed at the point of entry, it ensures fresh, odor-free water reaches every fixture in the home from a single connection. Metered regeneration keeps water consumption efficient by running only when needed. Supplied by Water Softener Plus, the system arrives nearly complete — just add the plumbing adapters that fit your lines — for dependable, low-maintenance, chemical-free sulfur treatment.

For the cleanest result, position the filter on a level base with room above the tank for valve service, near both the main line and a drain. Some homeowners with combined issues add this sulfur filter ahead of a water softener, treating odor first and hardness second. With no chemicals to handle and no feed pumps to prime, the unit settles into a quiet, reliable routine that keeps showers and drinking water free of that telltale rotten-egg smell.

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.
