TOKYO -- Yamashin-Filter, a Japanese manufacturer of filters for construction machinery, has developed a high performance replaceable face mask insert boasting extended particle-blocking performance and plans to ramp up mass production of its own mask next month as demand for protection soars with the spread of the novel coronavirus.
Yamashin has adapted its manufacturing technology for filters in construction machinery to applications in clothing and farming, but now is aiming to expand its consumer-oriented business amid a critical shortage of face masks.
