The Aqua-Pure AWS100M Water Softener is ideal for smaller homes with up to 1.5 baths. The Aqua-Pure AWS100M Water Softener removes scale causing minerals that are commonly found in hard water areas, including hardness caused by minerals and salts dissolved in water. It gives you brighter clothing, cleaner dishes, and less detergent usage. The AWS100M utilizes smart electronics with a 9 volt backup. It monitors water consumption and adjusts to changing water usage and has a metered control valve. This minimizes the use of electrical energy and cuts down on wastage of water. The AWS100M scrubs the ion exchange resin during backwash. This helps to maintain maximum resin and system performance. The multi-level salt shelf traps dirt (sediment) and debris away from the brine draw area, enabling the use of inexpensive types of water treatment salt reducing maintenance.
