We use this granule for the In-Ta-Fil using our Saeco Fully automatic unit. The granulate is well suited for and provides soft water. The machine must be decalcified only rarely, although we just switch the granules every two months. Daily water flows for about 4 average cups of coffee by. Man should only ensure that the granules are always covered with water, otherwise there is here faster to contamination. The granules are far more favorable than the original Saeco (quite apart from the cartridge), but for a "little powder" still a lot of money.
