Abstract
A portable vessel for fluids has an integrated filtration system. A pressing assembly fitted to the vessel includes a stopper, a rod having a top end and a filtration assembly. A vessel top receives the pressing assembly such that the rod of the pressing assembly is slidably attached to a bearing of the vessel top. A gasket attached to the filtration element maintains a seal between the inner surface of the vessel and an outer perimeter of the filtration assembly and the orientation of the rod is maintained by the gasket and the bearing. In use, pressure applied to the pressing assembly drives the filtration assembly through the vessel causing water to be filtered as it passes through the filter element.
