In daily life, when many people buy masks, we may see the non-sterilization words on the outer packaging, and many people often feel that these masks do not provide protection for ourselves. But in, this view is wrong. Today, Musk Medical will tell you in detail the difference between sterilization and non-sterilization masks. After reading this article, I will understand when you buy a mask.

1) sterilization and non-sterilization problems, into the standard "microbial index", are divided into sterilization and microbial limit index, that is, the packaging logo with "sterilization" or "sterile", non-sterilization mask refers to the mask that is not processed in the sterilization process. According to the current national management of medical device aseptic SAL(aseptic assurance level) to 10-6

2) sterilization and non-sterilized masks are also done in a dust-free workshop of 100,000 levels, other indicators such as filtration efficiency or airflow resistance are the same requirements, the difference is whether the final sterilization process of the finished product. At present, the sterilization of medical masks is sterilized by ethylene oxide EO. Because ethylene oxide is flammable and explosive, carcinogen and respiratory protective products, it must be 7-14 days after EO sterilization, until the residual amount of ethylene oxide drops to 10ug/g.

3) non-sterilization normally can meet the microbial limit index after the above 100,000 dust-free workshop. In other words, non-sterilization masks are also strictly managed in accordance with the medical device management methods, which is safe enough to meet the protection needs of the daily public.

Why does 4) have sterilization types is mainly because the things that need to strictly control the microbial environment, such as the ICU, operating room, are sterile and do not cause other bacterial infections in the patient.

 Both 5) sterilization type and non-sterilization type are managed and produced in the dust-free workshop according to the second-class medical equipment, the difference is only whether the final sterilization process, this difference has no impact on the use of the public and other places that do not need to strictly control the microbial environment, as long as the product meets the corresponding standards.

In addition, Musk Medical wants to remind its friends here that the epidemic has not passed, and the school is about to protect its own health and safety is to wear a mask and take precautions.
