This coffee filter replacement fits your filter by entering your model number. This applies to CA6903, not CA6702. Effective filing: Lone exchange resin effectively prevents limescale deposits. Besides, the high-quality activated carbon from coconut shells can absorb residual chlorine, which improves the taste of your coffee. No limescale removal: you do not need to descale the coffee machine. This coffee machine filter prevents limescale deposits by replacing the calcium and magnesium ions contained in the water. Extending the maintenance interval of your coffee machine to 3 months also reduces heavy metals and other potentially harmful contaminants in the water tested by a third party laboratory.
