Abstract:
1. An electrostatic particle filter for removing particles from air, the electrostatic particle filter comprising a filter medium with first and second opposite sides, a first electrode and a second electrode, the first electrode and the second electrode being permeable for an air flow containing particles, and the first electrode and the second electrode being conformally provided on the first and second opposite sides of the filter medium, respectively, characterized in that the first electrode, the second electrode, and the filter medium are arranged to allow an electrical conduction current through the filter medium, and the first electrode is a moderately-conductive electrode having a sheet resistance in a range with a lower boundary value of about 10 6 Ohm per square and an upper boundary value of about 10 12 Ohm per square, at a relative humidity of 30%.
