Abstract: A filter package having a long shelf-life and containing substantially no contaminants comprises a filter cartridge, a flexible bag surrounding the filter cartridge having walls comprising a polymeric material impervious to microorganisms and liquid water, a venting mechanism formed in a wall of the flexible bag, and sanitized water sealed inside the flexible bag and immersing substantially 100% of a volume of the filter cartridge. 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.
