Although these masks have not been tested medically, we have followed all guidelines we could find to be sure they are functional and not just fashion masks.
 
-NO METAL NOSE PIECE (we have found that the nose piece can be a problem for some users and the fit is the same without it. The filter lining is stiff and holds the contoured shape of the mask on its own)
 
-Silky black fabric outer and lining
-Recommended polypropylene filter enclosed inside
-Elastic ear straps- tie where you want them
-machine washable with like colours
-Tapered bottom edge for smoother fit at ear
