The projection, projects either into or out of the chamber, preferably at a base region of the filter cartridge. In particular, the plurality of orifices may be formed as a plurality of slits provided on one or more faces of each projection. The outlet configuration is configured to prevent clogging of the outlet by the granular filter material and may be useable with or without a mesh to cover the plurality of orifices. |
