Fluid Penetration Resistance Final Report

PURE-MSK is FDA 510(k)-cleared for use as a surgical mask to provide a physical barrier to fluids and particulate materials.   It is intended to be worn by operating room personnel during surgical procedures to protect both the surgical patient and the operating room personnel from transfer of microorganisms, body fluids, and particulate matter. 

PURE-MSK is being marketed as a face mask under the Emergency Use Authorization for use as source control by the general public as well as by HCP in healthcare settings as to help prevent the spread of infection or illness during the COVID-19 pandemic.  It is not an N95 mask (also known as a filtering facepiece respirator), and it is not NIOSH-approved.
