Abstract: An improved air ionizing apparatus that may be used as part of an air filtering system. The apparatus consists of an air passageway with at least one negatively charged ionizing member therein and a conductive strip, positively charged with respect to the ionizing member extending around at least a major portion of the interior periphery of the outlet of the passageway. The conductive strip attracts the negative ions, causing them to disperse as air directed down the passageway propels them toward and through the outlet of the passageway.
