Abstract: A mask assembly having antimicrobial properties is provided. The mask is preferably worn on a user's face and it comprises a material layer, preferably a polyester fabric, and an applied emulsion or combination of chemical components (a silver containing stabilized solution and a phosphorescent compound). The combination provides enhanced antimicrobial properties in the mask via the silver containing stabilized solution and the phosphorescent compound, which emits a controlled field around the mask of microbe destroying UV-C radiation, preferably in the 200-290 nm wavelength range. The emulsion may be applied to other surfaces wherever antimicrobial properties are desired.
