ABSTRACT:
A high efficiency air filtration method and apparatus utilizes a fibrous filter medium that is polarized by a high potential difference which exists between two electrodes. The electrodes include an insulated electrode and an uninsulated electrode. A corona precharger is positioned upstream of the electrodes and filter. The corona precharger creates charged particles that have an opposite charge (e.g., a positive of negative charge) determined with respect to a polarization dipole proximal to the insulated electrode. These particles cancel a trapped charge that tends to accumulate on the filter surfaces proximal to the insulated electrode.
