During the epidemic, the amount of masks was relatively tight. At that time, if you wanted to buy masks, you almost had to grab them. There was little information about masks. Later I learned that there are many types of masks, such as: Disposable face mask ordinary masks, medical masks, disposable masks, etc.
So what is the protective effect of ordinary masks? What pollutants can be isolated?
1. Ordinary masks can be used to block the splashes exhaled from the oral cavity and nasal cavity, and can be used for one-time hygiene care in ordinary medical environments with low protection levels. It is suitable for general health care activities, such as sanitation, liquid preparation, cleaning bed units, etc., or barrier or protection of particles other than pathogenic microorganisms such as pollen.
2. At present, there are many kinds of masks on the market, and the name of the mask is written with medical, protective, etc., which may not have the effect described, so how do we judge? Regardless of whether it is a medical protective mask or a surgical mask, ordinary medical masks are medical devices and are included in the management of medical devices. my country's production and management of medical devices are quite strict. Therefore, if conditions permit, try to choose mechanical brand products. Masks with medical device production license and medical device product registration certificate.
3. When purchasing, you should also pay attention to the implementation standards of masks. Different implementation standards have different protection effects. Don't just pay attention to the product name. If the implementation standard on the packaging is YY 0469-2011, this kind of mask is a medical surgical mask, which has a higher protective effect than ordinary medical masks. Ordinary medical masks generally implement the relevant registered product standards.
