Ordinary cloth will not keep viruses out -— they are 0.03 MICRONS in size. The rest of your instructions are good. Buy a high end furnace filter that will filter viruses, and remove the fabric from the frame. Use it instead of cloth. Staple, tape or sew a “tuck” in the sides to conform it to the shape of your face.
