The Ultimate High Efficiency "FE" Twin is an exclusive Vern Dale Water Experts softener that can remove more iron than a standard water softener. This system uses a special resin with an increased surface area to remove more iron and uses less water to clean itself. The Twin "FE" also has an iron-out additive system that helps rinse the iron off the resin bed during cleaning. The twin tank "FE" cleans with softened water to prevent iron and hardness buildup in the tanks during cleaning and is the most efficient softener we sell.
