Ordinary medical masks are used to block sprays from the oral cavity and nasal cavity. It can be used for one-time sanitary care in a general medical environment, with the lowest level of protection. It is suitable for general sanitation and nursing activities, such as sanitation, liquid preparation, cleaning bed units, etc. Or the barrier or protection of particles other than pathogenic microorganisms such as pollen.
It meets the relevant registered product standards, and generally lacks filtration efficiency requirements for particles and bacteria. Or the filtration efficiency of particles and bacteria is lower than that of medical surgical masks and medical protective masks. Only aerosols with a diameter of 0.3μm can achieve a protective effect of 20.0%-25.0%. Can not reach the filtration efficiency of particles and bacteria. It cannot effectively prevent pathogens from invading through the respiratory tract, and cannot be used for clinically invasive operations. Nor can it protect against particles and bacteria and viruses. It is limited to a certain degree of mechanical barrier to dust particles or aerosols.
Instructions
1. Use a mask to carefully cover the mouth and nose and tie them firmly to minimize the gap between the face and the mask.
2. When in use, avoid touching the mask-after touching the used mask, for example, to remove or clean the mask, wash your hands with soap and water or use an alcohol-based hand sanitizer.
