A flexible, loose-fitting mask designed to be placed over the mouth and/or nose of a member of the general public to permit normal breathing while protecting the wearer from the transfer of large particles (e.g., blood, body fluids, and airborne particulate materials) from the environment; it is not a form-shaped filtering device (i.e., not a respirator). It is made of a flexible, porous fabric or paper material and is typically secured using elastic head straps or ties; it may incorporate a forming nosepiece (metal wire). This is a reusable device.
