A flexible, loose-fitting mask designed to be placed over the mouth and/or nose of a healthcare worker to permit normal breathing while protecting the patient and wearer from the transfer of large particles (e.g., blood, body fluids, and airborne particulate materials). It does not include an antimicrobial/antiviral agent(s) and 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) and/or transparent face/eye visor. This is a single-use device.
