The present invention relates to a conducting filter ( 110 ) adapted for gas purification and a filter assembly ( 150, 200, 300, 400, 500, 600 ) comprising such filter. The conducting filter is made from a polymer which has received significantly increased electrical conductivity by a doping process. Such doped polymer are referred to as synthetic metals. Thanks to the electric properties of the synthetic metal, may the filter according to the invention, comprising such polymer, be supplied with electrical charge and whereby maintain its efficiency with regards to the electrostatic properties during operation. In the filter assembly according to the invention, the conducting filter is supplied with electrical charge by connecting it to an high voltage source.
