In less than year, Servutas and his business partners shifted from making and selling vaping devices and accessories in a Virginia Beach industrial park to hearing the hum of 23 machines unspool, cut and fold material into 1.1 million disposable surgical masks a day. Of the more than 100 million masks they’ve made so far, 70 million were delivered to the U.S. government to be passed on to the Federal Emergency Management Agency. Most of the company’s customers are what one might expect: hospitals, health facilities, retailers.
