Mask selection
Medical surgical masks and N95 masks can be selected to prevent COVID-19.
N95 mask has the best protective effect, followed by medical surgical mask and general medical mask, and the general protective mask has the worst protective effect.
To prevent COVID-19 from wearing masks, N95 masks should be the first choice. This mask is close to the face, with good air tightness, and can effectively prevent COVID-19 from infecting human body through respiratory tract.
Medical surgical masks are commonly used in surgical operations. They are divided into three layers, including hydrophobic layer, filtering layer and skin-friendly layer. The filtration rate of bacteria can reach 95%, which can effectively prevent the infection of bacteria and viruses.
Ordinary protective masks are not effective in preventing COVID-19, so they are generally not recommended.
