Abstract: The present invention is directed to a water container. The water container comprises a fluid path defined by a rigid fluid reservoir, a filter and a water outlet having an open position and a closed position; a fluid inlet, and a pump coupled to the fluid inlet. The pump comprises a non-return valve and a piston shaft through which a piston head may be moved, the piston head being coupled to a piston rod slidably moveable through an orifice at a first end of the piston shaft, wherein the orifice is sealed about the piston rod such that, in use, operation of the pump pumps fluid from a fluid source in communication with the fluid inlet, through the non-return valve and into the fluid reservoir so as to pressurise the fluid reservoir such that, when the water outlet is in the open position, a pressure differential induces a flow of water along the fluid path through the filter to the water outlet. The piston shaft is substantially surrounded by the filter.

Abstract: A portable water filtration device is provided. The portable water filtration device comprises a housing defining an interior volume, said housing comprising; an input port for receiving water under pressure from an external source, and; an output port having an open position and a closed position. The device further comprises; a filter comprising an an array of hydrophilic capillary fibre membranes, said filter being positioned within the housing so as to form a fluid path between the interior volume of the housing and the output port such that, in use, when the output port is in the open position, water received at the input port flows under a pressure differential induced by the external source through walls of the capillary fibre membranes to respective open ends of the capillary fibre membranes to the output port, and further wherein; the filter fills at least 65% of the interior volume of the housing.
