An air treatment system which includes a wire-like corona electrode and an air permeable target electrode arranged concentrically around the corona electrode with the electrodes connected to a d.c. voltage source having a voltage causing a corona discharge at the corona electrode and an ion wind through the target electrode. The target electrode may have a substantially cylindrical configuration, in which case air flows axially into the target electrode through one or both of the open ends thereof and exits from the target electrode radially through its air permeable wall. The target electrode may also be divided into two or more separate parts arranged essentially concentrically around the corona electrode in mutually uniform spaced relationship.
