Abstract
An air ionizing apparatus that produces both positive and negative ions has a housing with air inlet and outlet passages, a plurality of spaced apart air ionizing electrodes and a high voltage supply which applies positive and negative voltages to separate electrodes. A fan creates an airflow that carries the ions out of the housing, the fan preferably being between the electrodes and the outlet passages to promote intermixing of positive and negative ions.
