During the epidemic period of Covid-19, it is important to guard against the epidemic situation and wear the mask correctly. What kind of mask to wear should be considered based on the individual's risk of exposure to the disease. Therefore, before choosing the mask, let's start with your risk level.

Persons at higher risk of exposure, such as health care workers working in emergency departments, public health practitioners conducting epidemiological investigations of close contacts, environmental and biological sample testers associated with outbreaks, etc. , wear a particulate matter respirator that complies with N95/KN95 and above.
Medical and nursing staff working in general outpatient clinics and wards; staff working in hospitals, airports, railway stations, supermarkets, restaurants and other relatively closed places; Those engaged in epidemic-related administrative management, police, security, express delivery, isolation at home and living with them are classified as middle-risk exposed persons and can wear medical surgical masks
People at Lower Risk are the public in crowded areas such as supermarkets, shopping malls, vehicles, elevators, indoor office environments, patients attending medical institutions (except fever clinics) , and children in child care institutions and school students who focus on learning and activities, to wear is advised to use a surgical mask only once, and children should opt for a protective product with comparable performance.
Indoor activities and scattered residents belong to low-risk exposed persons and may not wear masks at home; in well-ventilated and low-density places, non-medical masks such as cotton yarn, activated charcoal and sponges, also has a certain protective effect.
