Liquid to be purified (e.g. insulating oil for capacitors or from an X-ray tube) is admitted at 4 and flows between a tubular filter body 3 of sintered glass particles and a cylindrical, earthed cathode 2. A direct voltage of, e.g., from 40-70 kV is applied to a central anode 8, e.g. of aluminium. Purified liquid is withdrawn at 5. Preferably the filter body is removable.
