Cargill Diamond Crystal potassium chloride is a low-sodium alternative to traditional water softener salts, designed for use in all types of residential water softening systems. This 40-pound bag contains up to 99.1% pure potassium chloride crystals that work by replacing hard water minerals with potassium instead of sodium.

The high-purity formula contains minimal insoluble content to help keep water softeners operating smoothly and efficiently. Potassium chloride functions identically to traditional sodium chloride salt in water softening applications, making it an easy swap for homeowners seeking to reduce sodium intake or those on sodium-restricted diets. The crystals dissolve effectively to regenerate water softener resin and maintain optimal system performance.
