In daily life, when many people buy masks, they often find these non-sterile words. When many people see these words, they often think that these masks are defective products and cannot play a protective role. In fact, this view is also wrong. Below, I will briefly introduce the classification of medical masks and the difference between sterile masks and non-sterile masks.
In fact, there are three main types of medical masks, one is disposable medical masks, the other is medical surgical masks, and the last is medical protective masks. The three types of medical masks have requirements for microbiological indicators. The indicators include two situations: one is non-sterile masks (some companies mark "non-sterile"), which should meet the microbiological control standards, that is, a certain amount of bacteria is allowed, but it must be Within the scope of control; the second is to sterilize masks, which do not allow bacteria to exist. Both non-sterilized medical masks and sterilized medical masks have protective functions, which can block droplets and achieve the purpose of preventing cross-infection. Both sterile and non-sterile disposable medical masks meet the YY/T0969-2013 "Disposable Medical Masks" standard and can be used.
