Nelsen AIO 13" x 54" Katalox Filter

The Nelsen AIO 13" x 54" Katalox Filter is the flagship of the AIO Katalox line, pairing the largest tank with premium Katalox Light media and an efficient Enpress Vortech tank. Built for large homes confronting iron, manganese, and sulfur, this single-tank air injection system delivers high-capacity, multi-contaminant treatment without chemicals, addressing several of the toughest well-water problems in one comprehensive unit.

Katalox Light media excels at removing oxidized iron, manganese, and hydrogen sulfide, the trio responsible for discolored, smelly, and staining well water. The system's air pocket oxidizes these contaminants as water enters the tank, and the Katalox Light bed then captures them. The Enpress Vortech tank improves backwash efficiency with its internal plate design, helping conserve water during the automatic daily regeneration managed by the Fleck 2510SXT valve.

With its 13" diameter tank, this premium system provides the greatest service flow and media capacity in the AIO Katalox range, making it the right fit for large families or properties with heavy, mixed contaminant loads. Katalox Light's versatility is invaluable where manganese accompanies iron and sulfur. The Vortech tank keeps regeneration water-efficient, and the included bypass valve eases service. Installing on the main line at the point of entry, this top-tier Nelsen AIO Katalox filter offers comprehensive, low-maintenance whole-house treatment for the most challenging well water.

As the flagship of the AIO Katalox line, this 13-inch system is built for the most demanding situations: large homes with high water use and complex chemistry involving iron, manganese, and sulfur together. Katalox Light's versatility and the Vortech tank's efficient backwash make it both capable and reasonably economical to run. A complete water test before purchase ensures this top-tier capacity is correctly matched, after which the system delivers comprehensive, chemical-free, whole-house treatment with the low maintenance the AIO platform is known for. Over time, treating three contaminants in one tank saves both effort and the cost of running separate systems.
