ClearTAC uses template-assisted crystallization to reduce the formation of hard water deposits. It can be used where conventional water softeners are banned. No chemicals or salts are needed, and there is no brine discharge. The system uses long-lasting media and is virtually maintenance free. Carbon reduces or eliminates chlorine taste and odor, while beneficial minerals remain in the water. The system passes the W-512 standard for physical water treatment devices, and two independent lab tests confirmed results of 90% or more effectiveness in reduction of scale buildup.
