Carolina Cotton Carbon Filter Face Mask - 50ct/box

Individual package, 98.8% BFE (Bacteria Filtration Efficiency)

These are a typical around-ear face mask, similar to what doctors and nurses wear. I opened one up to try it on. They feel well made. I can imagine tossing some of these in my various emergency kits--since they're individually wrapped they'll stay clean. I'm happy with the purchase and I recommend them.
