An ostomy filter comprises a filter housing (24) having a cylindrical bore (28) within which is received a cylindrical filter element (36). The filter eleme nt (36) has an axial length greater than its radius, and is slid longitudinally into the bore (28). A user can select a filter element to use having appropriate flow rate characteristics to suit his or her needs. The filter may be a discrete filter mounted on the pouch wall, or it may b e incorporated into a stomal aperture coupling member (16) for the pouch. In one form, the filter element (36) can be replaced by inserting a new filt er element through the outer end (30) of the bore, to displace the previous filter element and eject it through the inner end (32) of the bore into the pouch. The filter element may contain superabsorbent for absorbing any liquid whic h leaks into the filter. The cylindrical filter element may be produced using conventional production facilities used in the cigarette filter industry. An elongate rod of superabsorbent, or superabsorbent containing, material i s also disclosed which can be inserted into a pouch, for example, a urostomy pouch, without the need for an additional applicator.
