Trash, keep looking...
These are complete trash, please continue to look for other masks if needed.  2 of three had several holes 1-2mm in the front where you would exhale, so mostly useless.  They are made from the thin foam that you would see over a picture frame.  If you find ones without holes, you might be able to use it 2x.  Do the rest of the world a solid and don't think anyone is protected by this garbage.  I am normally not as irritated by poor quality, as I realize there are levels, but you could not strain coffee with these, and I can see through them
