The next generation of respiratory protective masks is expected to have lower burden filters with increased protection for the Warfighter. A market survey was conducted to identify novel commercial filtration media with low-pressure drop and high efficiency. Performance requirements for the filtration media included a pressure drop of or = 5 mmH2O and a particulate filtration efficiency of high-efficiency particulate air (99.97%) or better. Three companies had products that met the performance criteria, and their representatives will be contacted for samples. Six companies had promising technologies, and their representatives will be contacted for more information. These novel aerosol filtration media and technologies will be characterized in-house to determine if they could be included in the next generation respirator., Prepared in collaboration with Battelle Memorial Institute, Columbus, OH.
