Abstract: A filter, for insertion into an inlet duct of a water filtration system, has an annular upper end delimiting an opening around a longitudinal axis and defining a filter diameter. A side wall extends, around the longitudinal axis, between the annular upper end and a bottom wall that extends opposite the opening. The side and/or bottom walls have orifices to allow water to flow therethrough while retaining solid elements. The sidewall wall comprises a plurality of arms that each extend between a lower edge, connected to the bottom wall, and an upper edge forming part of the annular upper end. Each arm extends along an adjustable inclination so that the filter diameter is variable according to the inclination of each arm. When the filter is inserted into the inlet duct, the inclination of the arms is adjusted so that the filter diameter is adapted to the inlet diameter.
