We, as filtration specialists, have developed and provided medical-grade* masks
made with YAMASHIN NANO FILTER™, a healthcare product,
created by utilizing our proprietary technologies.
|“Medical grade” refers to a mask grade meeting the N95 standard set by the National Institute for Occupational Safety and Health (NIOSH). This standard is cited in the Guideline on Maintenance of Medical Equipment and Materials in Medical Systems for new influenza and other infectious diseases,” issued by the Ministry of Health, Labour and Welfare, as one of effective mask standards. The results of PFE tests by the Kaken Test Center and BFE/VFE tests by Nelson Labs demonstrate that the filtration performance of YAMASHIN filter masks is comparable to that of N95 masks.|
In recent years, the risk of health damage has been increasing due to infectious diseases, including the new coronavirus, and fine particulate matter (PM2.5).
Under the circumstances, to make a social contribution as a filter manufacturer, YAMASHIN has commercialized medical-grade* masks and replacement inner sheets made using YAMASHIN NANO FILTER™. In response to the ever-increasing demand for masks, we are thus helping to reduce the risk of health hazards.
