A mask with at least one filtering layer that includes a fabric made of non-conductive polymer fibers embedded with nanoparticles of two different metals is provided. The population density of the nanoparticles of the two metals on the surface of non-conductive polymer fibers is configured such that the adjacent nanoparticles of the two metals have an average distance of two micrometers or less. The two different metals are selected such that the electric field intensity generated between the nanoparticles of the two different metal through the aerosol particle inactivates the microorganisms that may be inside the aerosol particle. When an aerosol particle comes into contact with the nanoparticles of the two metals, the aerosol acts as an electrolyte between the two metal types and a potential difference and an electric field is generated, through the aerosol particle, between the nanoparticles of the two metals.

Using facial masks and shields are so important for those who work in conditions that should use masks and shields to protect themselves from diseases. To put an end to a respiratory ailment like covid-19 pandemic, ordinary people should wear masks or shie lds all day long, too. Thus, using masks and shields may arise different challenges for individuals. HAMED GMSH can help reducing the difficulties related to these circumstances and enhancing protective effects of masks and shields of any kinds, like general, surgical, respiratory, deodorant and so on. The idea of this invention is to use glues, liquids, solids or other sticky materials, for the purpose of holding masks and shields on humans' faces in replace of straps/bands or only nose wires. Key words: mask, shield, facial, face, surgical, deodorant, general, glue, stick, adhesive.

A system and method for implementation of an improved weld pattern for the retention of straps to a face mask, configured to maintain maximum strength of the strap(s) without the use of glue or complete encapsulation via fabric welds. Proximal welds are positioned above and below ends of the straps without contacting the strap itself. The proximal welds are horizontal welds along the primary axis of the straps. The proximal welds are configured to reinforce primary vertical welds disposed along the very ends of the straps. A strip of weldable material is disposed atop the ends of the straps to facilitate the implementation of the horizontal and vertical welds.
