Abstract: Battery-powered smart electronic Air Filter Module (AFM) adapted for retention in an orifice of a face mask and adapted to be positioned in front of the user's mouth for prevention of transmission to or from the wearer of harmful particulates, bacteria, and viruses with less impediment of the wearer's breathing or speaking, comprising: an electrostatic field (EF) generator, an electromagnetic field (EMF) generator under intelligent breath sensor control adjacent the EF generator and adapted for providing directional polarization to particles ionized by the EF generator, anterior and posterior porous frame portions retaining the EF generator, and an electronic microcontroller system operatively connected with, and adapted to selectively energize, the EF generator and the EMF generator.
