ABSTRACT:
A filter assembly for a flexible, portable bottle having a sealing cap including a filter attached to the interior of the cap to filter out substantially all INORGANICS, ORGANICS, RADIOLOGICAL CHEMICALS AND MICROBIOLIGY. The filter assembly also may include a second filter or Iodinator sealed in the flexible bottle to further remove micro-organisms from water passing therethrough. The filter assembly is designed so that the flexible bottle must be pressurized, as by being hand pressed, after it is filled with water to force flow of water through the either or both of the filters. The filter in the cap includes a check valve to allow the bottle to be repressurized after water has been dispensed from the bottle.
