Antiviral medical face masks offer an easy breathing, comfortable design for your face along with safe, high-barrier protection. Curad BioMask inactivates 99.99 percent of tested influenza viruses within five minutes contact with the surface of the facemask. Tested on specific seasonal flu viruses Pandemic H1N1, Avian, Swine and Equine, this universal, standard flat mask with pleats has a hydrophilic plastic coating that rapidly absorbs aerosol droplets away from the outer surface of the mask. The first and second layers of the mask are treated with different compounds that inactivate influenza viruses. Rapid absorption ensures the influenza A and B viruses are wicked away from the outer surface. In the outer active layer, viruses are inactivated by exposure to a low pH environment. BioMask meets ASTM F2100-07 standard: High-Barrier surgical facemask.
