ScaleBlaster is an innovative, state-of-the art, electronic water conditioner that is installed on the incoming waterline entering the home. A signal cable is wrapped around the outside of the pipe and is connected to the enclosure. The unit produces a unique sound wave that alters the calcium molecules in the water, causing them to lose their “adhesive” properties. This removes existing limescale and keeps it from forming again. ScaleBlaster requires absolutely no maintenance, salt, chemicals nor any filters to replace.
