Morton 25 lb. Clean & Protect Water Softening Pellets are sized right for smaller households with lower water consumption. They are easier to lift and handle, featuring a comfort grip handle, easy open tear strip, strong graphics, and product detail. These pellets contain resin cleaning additives that keep the softener running better and longer, reduce iron build up, extend softener life with continuous use, and help improve appliance and water heater efficiency. Endorsed by many leading softener brands and the only water softening salt to earn the Good Housekeeping Seal, they eliminate messy tank clean up and are NSF certified to NSF/ANSI/CAN 60.
