Tru-Soft® COM-PAC Solar Salt Pellets for water softening are produced from naturally evaporated solar salt. These are grown and selectively harvested from a salt lake in Carlsbad, New Mexico, then washed and compacted to produce large oval-shaped pellets. A competitive choice for water softening, Tru-Soft® COM-PAC Solar Salt Pellets can help reduce scale buildup from hard water, thereby helping increase the lifespan of pipes, fittings, heaters, boilers and other appliances. Since scale buildup can impair the efficiency of your appliances, our water softening products could even help lower your energy bills! The Water Quality Research Foundation found that softened water can effectively clean your clothes with 50% less detergent on the cold water setting.
