Abstract: The present invention concerns a water filter designed to be inserted into a drinking water circuit. The water filter has a support designed to house removably one or more different filters each having a different filtering property and adapted to be mounted either independently of each other or associated in a particular combination so as to effect a filtration of the drinking water according to its composition.

Abstract: Filter holder having a dish (1) designed to be mounted on an "espresso" coffee machine and having a cup (2) whose bottom wall forms a filtering surface (3) and which is designed to receive a quantity of coffee, the fineness of whose grounds may vary. The dish also has a collection chamber for froth (4) provided between its bottom (10) and the filtering surface (3), and communicating via an exit passage (5) with distribution funnels (6) enabling the infusion to flow out of the dish (1). The cup (2) has structure for partially blocking the filtering surface (3) of the bottom wall of the cup (2), this structure being formed by at least one blocking area (9) arranged in the bottom (10) of the dish (1) and distant from the bottom (10) at a certain level (A).
