Medical protective masks are one of the professional medical mask products, belonging to the category of medical masks. Manufacturers must comply with relevant regulations when producing medical masks, that is, they must produce in accordance with the national standard GB 19083-2010 'Technical Requirements for Medical Protective Masks'. In addition to the basic standards, medical masks must also cover the nose and the user’s mouth, and should Has good facial tension. The corresponding standards for disposable medical masks are: YY/T0969-2013 disposable medical masks, YY 0469-2011 medical surgical masks and GB19083-2010 medical protective masks. All copper mask
products must be produced in strict accordance with relevant standards. The size of the medical protective copper mask: If it is a rectangular mask, the length of the unfolded center size should be no less than 17 cm, and the width should be no less than 17 cm. If it is a dense arched mask, its horizontal diameter is not less than 14cm, and its longitudinal diameter is not less than 14cm. What is the filtration efficiency level of medical protective masks? At present, there are three main levels of filtration efficiency of medical protective masks, namely the first, second and third levels. Among them, the first stage must reach a filtration efficiency of 95, the second stage must reach a filtration efficiency of 99, and the third stage must reach a filtration efficiency of 99.97. N95 masks are relatively common in the market and are familiar to many people. They are first-class medical protective masks with a filtration efficiency of 95. In contrast, the filtration efficiency of medical surgical masks is low, and the production standard is above 70, which has a good effect on particle filtration efficiency. Use disposable masks for 4-6 hours. If they are used continuously for more than 4 hours, they need to be replaced. However, in special circumstances, such as taking them off and not wearing them in between, or temporarily unable to buy a new copper mask, there is nothing wrong with wearing an old mask without wearing a copper mask.
