Water softeners come in an array of sizes. While it might seem that bigger is better, this is not necessarily true. The WaterMax® system utilizes smaller beads and a fine mesh resin that provides more filtration surface area to soften water. The vacuum-packed resin provides maximum capacity in a minimal amount of space. The patented Directional Flow Screen system is another feature that makes the most efficient use of the resin beads. With the WaterMax®, the resin bed is protected by screens and the whole-house dirt and sediment filter so space is not wasted on freeboard, the empty area in conventional water softeners that allows a churning of resin during regeneration.
