The Wpro anti-limescale magnet C00375499 helps to reduce the build up of limescale on the heating element of your appliances. As the water passes through the powerful 20.500 Gauss magnets, the calcium molecules are prevented from forming into limescale, resulting in less build up on the heating element without the use of chemicals. It also optimizes washing results for laundry and kitchenware. It is easy to install on any brand of washing machine, washer dryers or dishwasher.
