Technical Field

Background
Coronaviruses are a large family of viruses known to cause the common cold and more serious diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The novel coronavirus is a new strain of coronavirus that has not been previously discovered in humans. After people are infected with coronavirus, the common signs of the person are respiratory symptoms, fever, cough, shortness of breath, dyspnea and the like. In more severe cases, the infection can lead to pneumonia, severe acute respiratory syndrome, renal failure, and even death. There is currently no specific treatment for diseases caused by the novel coronavirus. However, many symptoms can be treated, so that the mask is worn according to the clinical condition of a patient, and the mask has an important effect of slowing down the spread of new coronary epidemic. German researchers find that effective wearing of masks can reduce the incidence of infection and growth of new crown diseases by 40%; yet another study published in the U.S. journal shows that masks are far more important than social distance and home isolation.
If the mouth mask is disinfected by using alcohol disinfectant which is available on the market, most people cannot bear sharp smell, even if the mouth mask is disinfected by using large-brand disinfectant such as Weilushi, hydrogen peroxide contained in the liquid can cause certain harm to human bodies, and the volatile smell can cause anaphylactic reaction to part of people.
