This anti-scale filter is easily installed between the faucet and the appliance's water supply hose, allowing it to have a direct impact on the incoming water. The filter uses a granulate specifically designed to reduce limescale, thereby extending the lifespan of the appliances. Regular use of the Wpro CAL300 can improve the efficiency of the appliances, leading to better cleaning performance. The packaging unit includes one filter designed for single use. This product is particularly recommended in areas with hard water, where limescale buildup is a common issue. The Wpro CAL300 is thus a practical solution for anyone looking to optimally protect their household appliances and maintain their functionality.
