The invention relates to a filter cartridge (46) for a safety workbench (10) and a safety workbench (10). The filter cartridge (46) comprises a hollow cylindrical filter body (48) of a filter material which surrounds an interior space (56) in the radial direction, an open lid (50) attached to one end of the filter body (48), which has an interior space (54 ) opening inflow opening (70) surrounds, as well as a at the opposite end of the filter body (48) arranged closed lid (54). To make it possible to reduce the pressure difference between the inflow side (36) and the outflow side (38) and / or to increase the flow rate of the air flowing through the filter body (48) without adversely affecting the filtering action and without changing the filter material According to the invention, the inlet opening (70) has a nozzle-like flow cross-section decreasing in the direction of the interior (56) and / or a projection (86; 92; 94) tapered towards the inlet opening (70) in the interior space on the closed cover (54) (56) survives.
