WATER PURIFICATION DEVICE

This invention concerns a fluid purification device. The device has container, a nozzle and a removable filter element. The container is preferably a bottle and has at least partially flexible sidewalls so that it is collapsible from a first, operative condition into a second, inoperative condition. The nozzle is connectable to the container and defines a first fluid flow path along which fluid flows when, in use, filling the container and a second fluid flow path along which fluid flows when, in use, dispensing fluid from the container. The removable filter element is carried by the nozzle such that it is positioned in the first fluid flow path so that the fluid is filtered when filling the container and positioned outside the second fluid flow path so that the flow of fluid is unobstructed by it when dispensing fluid from the container. The invention also concerns a method of filtering a fluid.
