What is the difference between sterile and non-sterile disposable masks?

Both sterile and non-sterile masks are made in a 100,000-level dust-free workshop. Other indicators such as filtration efficiency or airflow resistance are all required to be the same. The difference is that the final sterilization process of the finished product without. At present, the sterilization of medical masks is EO sterilization with ethylene oxide. Because ethylene oxide is flammable, explosive and carcinogen, it is also a respiratory protection product. It must be 7-14 days after EO sterilization. Resolver until the residual amount of ethylene oxide drops below 10ug/g.
Non-sterile masks can meet the microbial limit indicators after being made in the above-mentioned 100,000-level dust-free workshop. In other words, non-sterile masks are also managed strictly in accordance with the medical device management method, and they are safe enough to meet daily routines. The protection needs of the public.
Why is there a sterile type? It is mainly because the things that need to be entered in medical places such as ICUs and operating rooms that need to strictly control the microbial environment are sterile, and will not cause other bacterial infections in patients.
As for whether the non-sterile masks we buy outside can be sterilized by themselves, my opinion is that it is not necessary. The key to the protective effect of the mask is the layer of polypropylene melt blown cloth in the middle, which is used to block particles. Or the virus vector works by two principles, one is achieved by the radial gap of the fiber, that is, if it is too large, it will not pass, accounting for about 30%, and the other is through the electrostatic adsorption of the electret melt blown cloth. Effect to achieve. For example, ultraviolet sterilization, steam sterilization, and even irradiation sterilization can reduce the electrostatic effect of masks, and this decline is more obvious. The repeated use of masks under special circumstances can be handled by the following news method.
