Built with advanced Granular Activated Carbon (GAC) technology, the PureWash Pre-Filter helps reduce chlorine, iron, sediment, odors, and other impurities that can interfere with oxidation-based laundry systems. By conditioning the incoming water before it reaches your washer, the filter helps maximize cleaning performance while promoting fresher, cleaner-smelling laundry. Perfect for homes with mild hard water or elevated chlorine levels, the PureWash Pre-Filter supports improved laundry results while helping extend the life and efficiency of your purification equipment.
