Reusable Protective Face Masks With Antimicrobial Copper Mesh-Based Filters

The Defense Systems Information Analysis Center (DSIAC) was asked about the development of tactical and surgical/medical reusable face masks that use Environmental Protection Agency (EPA)-approved copper mesh antimicrobial filters. DSIAC coordinated with the developer to obtain references on the effectiveness of the copper mesh, determine an estimate of production capability, and produce a white paper. DSIAC researched recent developments involving the use of copper and copper/silver, nanoparticle, embedded fabrics for antimicrobial purposes, as well as previous uses of and issues with silver, nanoparticle, and embedded fabrics. All materials were provided to an Information Analysis Center representative, the COVID-19 White House Task Force, and the U.S. Army Combat Capabilities Development Command Manufacturing Technology office.
