The limescale protection cartridge was specially developed by Swiss engineers at Laurastar and allows you to filter tap water for ironing. Thanks to its limescale protection, the lifespan of your iron is extended. The salt protection improves steam quality. The rust protection helps maintain the components of the steam generator. The limescale protection cartridge needs to be replaced as soon as the limescale protection granules have completely turned brown.

Note: A compatible filter insert is required for the use of this cartridge.
