The EcoWater Systems ERR 3000 is more than a water softener, more than a conditioner and more than a water filter. It's a water refining system designed specifically for municipal water applications. It will clean, soften, filter and reduce chlorine taste and odor in your water. This comprehensive, state-of-the-art water treatment system features an internal computer that monitors the amount of water you use and prompts system regeneration for actual and predicted future use.
