Abstract
A rigid filter for capsules suitable for extracting beverages, comprising a flat body having a plurality of through filtering holes, which are sized so as to block the passage of solid particles and allow passage of brewed water or beverage, wherein the holes have a substantially symmetrical shape with respect to the middle plane of the flat body, so that the filter can be inserted into a capsule without taking care of the orientation of such holes with respect to the powdered substance within the capsule.
