摘要：
A liquid filtration method and device, for example a drinking straw with a mouthpiece, and a bundle of hollow fibres. The open ends of the fibres are embedded in a base and provided in a compartment between the base and a liquid outlet. Water or other liquid flows into the inner volume of the hollow fibres and from there through their filtering membrane walls and into the compartment before the liquid flows out through the liquid outlet, for example the mouthpiece.
