Abstract
Air ionization apparatus includes a plurality of air ionizing electrodes connected to a source of high ionizing voltages, and includes a bias source connected to supply bias voltage to a reference electrode positioned near the air ionizing electrodes to alter the field gradients thereabout to selectively enhance production of positive or negative air ions in response to levels and polarity of bias voltage supplied to the reference electrode.
