Abstract
A device for removing airborne contaminants and inhaled biopathogens, particularly particulate or aerosol contaminants, from respired air that can be either stationary or incorporated into a garment or accessory worn upon the body. In a preferred embodiment, a negative electrode is connected to voltage multiplier and modulation circuit and then to a discharge electrode having an electron emissive surface disposed near the wearer's airway. The positive (counter) electrode is similarly disposed away from the airway such as, for example, near the forehead. Electrons, ejected from the electron emissive surface, transfer a negative charge to airborne particulate contaminants which are accelerated toward, and collected by, the counter electrode.
