An electrostatic air cleaning device includes an array of electrodes. The electrodes include corona electrodes connected to a suitable source of high voltage so as to generate a corona discharge. Laterally displaced collecting electrodes include one or more bulges that have aerodynamic frontal “upwind” surfaces and airflow disrupting tailing edges downwind that create quite zones for the collection of particulates removed from the air. The bulges may be formed as rounded leading edges on the collecting electrodes and/or as ramped surfaces located, for example, along a midsection of the electrodes. Repelling electrodes positioned between pairs of the collecting electrodes may include similar bulges such as cylindrical or semi-cylindrical leading and/or trailing edges.
