Wear it when in contact with patients with airborne or close-range droplet-borne respiratory infections. It can filter particles in the air and block droplets, blood, body fluids, secretion droplets, etc. It is a one-time-use product. Medical protective masks can prevent most bacteria, viruses and other pathogens. WHO recommends medical personnel to use protective masks against particulate matter to prevent virus infection in the hospital air. Important technical indicators include non-oily particle filtration efficiency and airflow resistance. The specific indicators are as follows:
1. Filtration efficiency: Under the condition of air flow (85±2) L/min, the filtration efficiency of sodium chloride aerosol with aerodynamic median diameter (0.24±0.06) μm is not less than 95%, which is in line with N95 ( or FFP2)... less
