“Are these HEPA bags or do they contain fiberglass material? I am thinking of using as a filter in a face mask but I want to know if”

• The box doesn’t specify the material but I can’t imagine there is asbestos in them. The Covid 19 virus is 1 micron and the filters only capture 3 microns so I’m not sure if it would work anyway. I read that an air conditioner filter that is supposed to capture among other things, virus particles may help. It specifically states virus’s on the box. Again, not sure if it actually works either.
