When the water is hard, when there is limescale in the water, it requires a greater quantity of laundry or dishwasher soap, therefore more water.
Each ball is equipped with a magnetic steel core to prevent crystallization and limescale deposits in the washing machine.
It reduces limescale deposits and therefore protects your machine from limescale for longer.
It reduces the amount of laundry soap by 50% by reducing the hardness of the water.
It reduces the amount of water needed for rinsing.
This ball is therefore economical and ecological.
The magnet loses its effectiveness after 5 years.
