CS AIO 13"x54" Sulfur System

The CS AIO 13"x54" Sulfur System is a high-capacity odor-control filter from Nelsen's Connected Series AIO™ Plus line, built for larger homes contending with hydrogen sulfide in their well water. The 13" x 54" tank provides the bed depth and flow capacity needed to keep rotten-egg odor in check across a busy household with multiple bathrooms and appliances.

Bluetooth control through the free Legacy View app for iPhone and Android™ makes the metered Connected Series valve easy to program and monitor. The AIO Plus design offers independently programmable air-draw and backwash cycles, so a fresh air pocket can be drawn daily without an added backwash, saving thousands of gallons of water each year, and the air charge is released slowly to protect the drain line. The system includes the Connected Series Air Draw Meter Control Valve, bypass valve, black polyglass mineral tank, and all media and support bed for sulfur reduction.

Air injection oxidizes hydrogen sulfide so it is captured in the bed and flushed to drain, restoring fresh, odor-free water without chlorine dosing. The larger tank suits bigger homes and heavier sulfur loads, and the metered valve regenerates only as water use requires. With media and support bed included, setup is mainly plumbing the tank and programming the valve via the app. Choose plumbing connections separately to match your supply lines, and add the optional chrome tank jacket for a finished look in exposed locations.

At the high-capacity end of the sulfur lineup, the 13" x 54" tank gives large households the contact time and flow to keep rotten-egg odor under control even during peak demand. Air injection oxidizes hydrogen sulfide at the source for genuinely fresh water with no chlorine feed. The metered Connected Series valve regenerates on demand, the daily air-draw cycle saves water, and the Legacy View app puts monitoring and adjustment within easy reach for hands-off, chemical-free odor control.
