3. Medical protective mask (KN95 mask)
Medical protective masks are generally used in environments with respiratory infectious diseases. They can filter particles in the air and block pollutants such as droplets, blood, body fluids, secretions, etc. The filtration efficiency of non-oily particles can reach more than 95%.

For people working in epidemic prevention and other departments, it is recommended to wear medical N95 masks, which can filter more than 95% of bacteria or viruses in the air and avoid invading the human respiratory system, while ordinary masks have no filtering effect, only for prevention and warmth. effect.
