N95 masks can prevent new coronary pneumonia. n95 masks are named because of their filtration efficiency of 95% of particulate matter under standard conditions. Some infectious diseases such as new coronary pneumonia are mainly spread through respiratory droplet transmission, and N95 masks can effectively block viruses and prevent droplet transmission caused by splashing of patients’ body fluids or blood, thus preventing viruses from entering the respiratory tract and causing the occurrence of new pneumonia.
The protection effect of N95 masks is better than medical surgical masks and single-use medical masks. When people with suspected symptoms go to the hospital, they need to wear particle protection masks without exhalation valves or medical protection masks.
