Ok, here is my solution for a face mask that has way more protection than a bandanna, and only requires scissors to make. Start with an M-13 air conditioning filter. It filters out viruses and is very hard for covid19 to get through. 1/4

Remove the filter paper and wire. It’s a pain in the ass but not that difficult. 2/4

Cut a piece of the filter material about 6x9 or so. Maybe a third of this piece here. 3/4

Open your bandanna and put your paper in there it will stick all by itself.

Then just fold up your bandanna and tie it on.

Hey it’s better than a scarf. Make sure to tuck it into your collar, and if it fogs up roll up some tin foil in a thin strip and put in the fold so you can shape it around your nose.
