CS AIO 10"x54" Sulfur System

The CS AIO 10"x54" Sulfur System uses Nelsen's Connected Series AIO™ Plus air-injection design to clear hydrogen sulfide odor from well water, with the added freeboard of a taller 10" x 54" tank. Bluetooth control through the free Legacy View app lets you manage settings from an iPhone or Android™ device. The extra tank height improves backwash expansion, making it a refined fit for homes with moderate sulfur.

The AIO Plus control valve supports independently programmable air-draw and backwash cycles, allowing a fresh air pocket to be drawn each day without forcing a backwash, which saves thousands of gallons of water annually. A slow release of the compressed air charge ahead of backwash avoids the explosive surge that can dislodge drain lines on conventional units. This configuration 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 trapped in the bed and flushed to drain, leaving water fresh and odor-free without chlorine dosing. The taller tank improves backwash expansion and contact time, helping the bed regenerate thoroughly each cycle. Because the media and support bed are included, installation is mostly a matter of setting the tank, plumbing it, and programming the valve via the app. Choose plumbing connections separately to match your piping, and add the optional chrome tank jacket for a polished installation.

The taller 54-inch tank gives this sulfur filter extra contact time and backwash expansion compared with the 44-inch model, which helps it handle stronger odor and keep the bed clean. Air injection oxidizes hydrogen sulfide at the source, so the rotten-egg smell is removed rather than masked, with no chlorine to dose. Add the Connected Series app control and water-saving daily air-draw cycle, and you have an efficient, low-maintenance odor solution well matched to typical family homes.
