A filter device for medical fluids comprises a plastics housing 24 having an inlet 28 and an outlet 30, a microporous filter membrane 26 in the housing between the inlet and outlet and a support screen 32 for the filter membrane downstream of the filter membrane, the screen and filter membrane being heat- sealed to the housing around their peripheries. The membrane and screen are sealed along a groove (36) formed in the housing around a flow passage between the inlet and the outlet. The housing includes a second membrane (58) serving as an air vent.
