Shamwow cloths are a 100% viscose/polypropylene thermally bonded non-woven cloth which is the material type used in medical grade masks such as the hard to find N95 and surgical masks. In addition to the Shamwow non-woven outer shell we have added a 100% cotton inner shell to provide extra comfort which also blocks any inert fibers from entering through the mouth.
Please see the links below for additional information which supports the Shamwow polypropylene viscose non-woven material as the same material type as what’s used in medical grade products.
