A device for cleaning of an air stream ( 40 ) from electrically charged particles (aerosols), the air stream passing through the device, the device including at least two electrode elements ( 20, 21 ) that are arranged in planes parallel to each other and at a gap distance (d) between adjacent electrode elements ( 20, 21 ). The electrode elements ( 20, 21 ) are connected to a respective terminal of a high voltage source, and spacers ( 11 ) are provided between adjacent electrode elements ( 20, 21 ). It is significant of the device that the spacers ( 11 ) constitute electrically insulating material, through which material the air stream may pass, and that the spacers ( 11 ) are arranged in such a way that all air transport through the device must pass through the spacers ( 11 ). |
