The filter cartridge includes a porous filter medium having a plurality of pores through which a fluid can pass between an upstream side and a downstream side of the filter cartridge and the sanitized water substantially permeates the pores of the filter medium. The venting mechanism includes a vent filter preventing the passage of microorganisms into the flexible bag.
