Nelsen AIO 13"x54" Sulfur Filter System

The Nelsen AIO 13" x 54" Sulfur Filter System is the highest-capacity sulfur unit in the standard AIO line, designed to clear hydrogen sulfide from well water in large, high-demand homes. This single-tank air injection oxidizing filter eliminates rotten-egg odor chemical-free, using oxygen and an automatic control valve to keep water fresh and pleasant at every tap throughout even the busiest household.

While in service, the system maintains an air pocket at the top of its large 13" x 54" mineral tank. As sulfur-laden water passes through the pocket, hydrogen sulfide is oxidized and captured by the filter media bed. The Fleck 2510SXT control valve automatically backwashes the system daily, flushing accumulated sulfur to the drain and replenishing the air pocket so treatment continues without intervention, salt, or chemicals for the homeowner to manage.
