Eliminates Scale Buildup - Hard water causes a white flaky build up (called scale) to form on appliances, faucets, and just about anything that it comes in regular contact with. By removing the hard water, this scale build up is stopped in it's tracks, so you don't have to worry about scrubbing it off any more. In addition, without the added wear and tear of scale buildup, your appliances and fixtures will last longer! Removes Ferrous Iron - this system is able to remove ferrous (clear water) iron, and some ferric iron. Removes Manganese - Manganese is commonly seen as a black "slimy" stain or build up. Meter Based Regeneration - This system uses a meter based regeneration process. This means that the water you use is measured and the system only regenerates when it needs to. If water needs increase the system regenerates more often to keep up. If less water is being used, the system regenerates less often to conserve water.
