What are the differences between sterile masks and non-sterile masks?
In daily life, when many people buy masks, everyone may see the words "non-sterile" on the outer packaging. Many people often think that these masks are defective and cannot provide protection for ourselves. But in fact, this view is wrong. Today, the editor will tell you in detail about the classification of medical masks and the differences between sterile masks and non-sterile masks. After reading this article, I will understand when I buy masks.
In fact, there are three types of medical masks, one is a disposable medical mask, the other is a medical surgical mask, and the last is a medical protective mask. Three types of medical masks have requirements for microbiological indicators. The indicators include two situations: one is a non-sterile mask, which should meet the microbiological control standards, that is, a certain number of bacteria are allowed, but must be within the control range; the second is a sterile mask, which does not allow bacteria to exist. Both non-sterile medical masks and sterile medical masks have protective functions, which can prevent droplets and achieve the purpose of preventing cross-infection.
It is worth mentioning that the sterile and non-sterile medical masks on the market are actually legally sold. There is no problem with defective products, but it should be selected according to different application scenarios. We know that sterile masks must be used in medical environments to prevent patients from infecting bacteria. These medical environments mainly include ICUs, operating rooms and other places where strict control of the microbial environment is required. On the contrary, in our daily use, this kind of sterile mask is actually not needed. You only need to wear non-sterile masks to meet the requirements of safety protection, because their protection levels are made in a 100,000-level dust-free workshop, which can meet the safety of use.
