31,000 Grain Water Softener (EP31)

The EcoPure 31,000-Grain Water Softener is ideal for families of 1 to 4 looking for a reliable way to soften their water. It eliminates embarrassing mineral stains, uses less detergent in the wash for cleaner, brighter and softer fabrics, and helps your water-using appliances last longer by allowing them to run more efficiently.

For peak performance in your high-efficiency EcoPure water softener, evaporated salt pellets or solar salt crystals with less than 1% impurities are recommended. It is not recommended to use any kind of block salt in EcoPure water softeners. Learn more
