The Wpro 484000008410 is a magnetic descaler designed to prevent limescale buildup in your household appliances. By utilizing a magnetic strength of 20500 Gs, it treats the water flow to protect the internal components of washing machines, dishwashers, and tumble dryers from mineral deposits. This device features a durable metal construction with a chrome-finished exterior, allowing it to blend in with standard plumbing. You can easily install it between the water tap and the appliance inlet hose, making it a practical choice for those using Whirlpool or Indesit machines who want to maintain their equipment without using chemical additives.
