There are a variety of face mask products, many of which are claimed to have antibacterial, haze prevention, safety protection and other functions, and even steam heating masks and other functions. Many people buy them for daily protection. Then, can these products meet the COVID-19 protection standards? 

 

In the case that ordinary masks cannot meet the requirements of novel coronavirus protection, medical masks have come into our sight and become an indispensable daily item. So, how does this thin layer of medical mask help us keep out the Novel Coronavirus?

 

Disposable medical masks and surgical masks labeled on the outer package of the product need to meet dozens of standards such as particle filtration efficiency, bacterial filtration efficiency, synthetic blood penetration, fabric flame retardant, gas exchange pressure difference, and even nose clip length. Both masks are widely used in novel Coronavirus containment scenarios, but the efficiency of virus filtration is not mentioned in laboratory testing standards for both products. So can medical masks be used for COVID-19 prevention and control? Wang Baojun, director of the National Center for Quality Supervision and Inspection of Textile Products, said: "Because this virus cannot exist alone, it must be parasitic on an object, a substance, such as my particle, or our saliva droplets. When we sneeze, if we're carrying the virus, it's on our saliva droplets, and the mask blocks the droplets, and when it blocks the particles, it actually blocks the virus.
