  • Method for enhancing collection efficiency and providing surface sterilization of an air filter
    Patent number: 6245126
    Abstract: A method of filtering air includes the steps of providing a filter element, providing a pair of electrodes sandwiching the filter element, applying a DC electrostatic field to the electrodes to produce attracting forces between particulates and micro-organisms contained in the air and the filter element, and intermittently applying a sterilizing electrical field concurrently with the electrostatic field. An RF, DC pulse, or AC power supply can be used to generate the sterilizing electrical field.
