The filter contains activated carbon extracted from coconut shell, which improves the taste of water by significantly reducing chlorine, chlorine derivatives, and organic compounds that cause odors and taste.

Polyphosphate is incorporated into coal to process scale and reduce its crystallization on heating elements.

Suitable for a refrigerator, minibar, coffee maker, drinking machine or under-tub purification system (except for reverse osmosis systems, which remove limescale at the highest level, so no polyphosphate is needed).
