Water softener/anti-limescale filter for domestic coffee machines, reduces limescale in the feed water.

• Works by ion exchange: traps the calcium and magnesium ions responsible for limescale, replacing them with sodium ions
• Fits directly inside the machine's water tank
• Before use, rinse it under cold running water to activate the resin

Protects the machine's boiler and hydraulic circuit from limescale build-up, while also preserving the taste and aroma of the coffee. Replace it periodically (roughly every 3-6 months, or after a given volume of water has passed through it) to keep it effective.
