Abstract: An ostomy bag (10) with a filter assembly having a gas filter (18) and a pre-filter (14) for preventing or delaying solid/semisolid matter and liquid from reaching the gas filter (18). The pre-filter (14) is at least substantially flat and comprises a number of constrictions (28), such as ribs extending along and between two inner surface parts (24, 26) of the channel (22). These constrictions/ribs (28) form narrower and wider passages where the gas may more quickly pass a narrow passage and where the wider passages tend to receive and hold the liquid, solid matter and semisolid matter. The constrictions (28) may be provided as a single, monolithic element, such as an extruded element.
