A capsule (1) for making beverages comprises a powdered food substance, and comprises a body (2) having a lower wall (3) and a side wall (4), and a lid (6) fixed to an edge (5) of the side wall (4). Between the lid (6) and the inner surface of the body (2) there is a chamber in which a rigid or semi-rigid filter (10) is positioned, coupled at a coupling portion (14) located on the side wall (4) close to the edge (5). The filter (10) extends between a rim (12) positioned close to the lid (6) and coupled to the coupling portion (14), and a bottom portion (13) positioned close to the lower wall (3), and separates the chamber into a first compartment (15), containing the substance, delimited at least between the filter (10) and the lid (6), and into a second compartment (16) partly positioned between the side wall (4) and the filter (10), delimited between the filter (10), the lower wall (3) and the portion of side wall (4) located between the lower wall (3) and the coupling portion (14). The second compartment (16) comprises openings (11) at the part of it positioned between the filter (10) and the side wall (4).
