  In this brief report we propose a new design of a medical mask with a plasma
layer, which provides both additional air filtration from microdrops, bacteria
and viruses due to the electrostatic effect and self-disinfecting of surfaces
by a pulsed barrier discharge. The key features of the mask are the mutual
arrangement of the layers, the direction of air flows and the synchronization
of the discharge with respiration, which ensures the safe wearing of the mask
and high degree of protection against pathogenic microorganisms.
