ABSTRACT:
A flexible water bottle is provided that includes an approach for filtering unfiltered water within the bottle. The bottle includes a filter assembly located within the cap of the bottle such that the filter assembly need not descend into the bottle cavity when the cap is screwed on, thereby not displacing water while screwing on the cap. The filter assembly has an axial flow orientation. An illustrated filter assembly includes paper filters covering the upper and lower ends and can include an activated charcoal filter in between the paper filters. Water is filtered when pressure generated by squeezing the bottle forces water from the bottle cavity through the filter along an axial flow path and out through a spout.
