Since the outbreak of new coronavirus in 2020, the demand for epidemic prevention materials, especially masks, has been in short supply. Mask production enterprises have expanded their production scale, and new and expanded enterprises have sprung up like mushrooms.

About two years ago, Yingzong Pharmaceutical, which specializes in the production of medical and health care products, saw that there are business opportunities for masks with filter function. They believed that the protection of general surgical masks is insufficient; the general N95 masks have poor air permeability and it is difficult to have viruses at the same time. Two requirements, filtering function and high air permeability; bring blue ocean business opportunities. The company thus cooperated with NAMI to produce NASK and seek technological breakthroughs.

Global public awareness of health protection has increased. For example, people who wear flu will wear masks. In addition, air pollution has become more serious in recent years, and cities in the Mainland have become more serious. Therefore, patented functional masks have a market.
