Make Your Own N99 Masks Without Sewing

This video shows how to make masks that help protect the wearer against harmful particles in their environment as well as help protect others from any harmful particles that the wearer might emit. The process uses a hot glue gun instead of sewing, and 2 layer HEPA vacuum bags that claim 99.7% effectiveness against microscopic particles, as well as commonly available tools and materials like a crimper/stripper, wire, pliers, tape measure, elastic bands, scissors, and electrical butt-splice connectors.
