Laurastar Anti-Scale Cartridges - SMART - Package of 3

The limescale filter cartridge, specially designed by Laurastar Swiss engineers, allows you to filter tap water before it is used for ironing.

By preventing limescale, they ensure a longer life cycle for your iron. They also prevent salt to improve steam quality. Anti-corrosive, they also prevent damage to boiler components.

The limescale filter cartridge should be replaced when anti-scale granules turn completely brown.
