A flexible water bottle is provided that includes an approach for filtering unfiltered water within the bottle, the system having a bottle cap, a nozzle formed in a first side of the bottle cap, a porous filter housing formed on a second side of the bottle cap, and a filter material located inside the porous filter housing, wherein the cap, nozzle and filter housing are formed as an integrated unit, which can be attached and removed from a water bottle as a unit. The system is preferably used with a disposable plastic water bottle. Water is filtered when pressure generated by squeezing the bottle forces from the bottle cavity through the filter along an axial flow path in design for the removal of a variety of biological, organic, or inorganic contaminants and filtered water comes out through a spout.
