Abstract
A filtration device of an airflow includes at least one porous filtering medium, at least two conductive elements arranged on either side of the filtering medium, at least one dielectric element interposed between the conductive elements, and at least one capacitor electrically coupled to the conductive elements. The device is configured to electrostatically polarize the filtering medium by capacitive charge storage.
