Detachable/disposable face shield for surgical mask
An electro-mechanical electrostatic air cleaner that combines a low air resistance dielectric fibrous filter material positioned between and electrically charged by two electrically resistant carbon coated screens. The screens are charged by a remotely mounted bi-polar power supply. A pair of post ionization electrodes charge particles in the air with opposite charges, causing the particles to agglomerate. A plurality of screens may be placed in an array for increased one-pass filtration.
