A surgical or permeable mask are used to stop contaminants from entering the mouth and nose of patients and, people administering healthcare or working in other areas where there is a potential danger of airborne contaminants such as particulates, pollutants, bacteria, viruses, or other dangerous particles entering the oral and nasal passages. The Present Invention provides increased filtration efficiency of these masks by creating an electrostatic field that attracts and captures oppositely charged contaminants and repels similarly charged contaminants.
