Additional care for household appliances. The Wpro anti-scale magnet provides a magnetic force that prevents the formation of scale in the water flowing through the machine systems. By breaking down calcium carbonate molecules (which make up the scale) into small ions, the magnet prevents them from settling, which usually happens when water is heated. This saves on electricity and detergent and has much better washing results. An easy-to-install magnet offers an ecologically cleaner alternative to chemical descalers.
