Everyone knows that now is the critical moment for the prevention and control of the new crown epidemic, and various information about protection frequently appears. Especially those masks such as medical masks, N95, KN95, etc. can effectively block the distance of virus transmission. There are also some non-medical, suchKN95 non-medical mask, One-time non-medical, etc. Slowly, many types of masks were produced, and they frequently appeared in our sight. So how to distinguish between non-medical masks and medical masks? Next, the editor will explain to you.

Let me explain to you the medical masks first. First of all, a medical mask is composed of a mask face and a tension band. It is made of one or more layers of non-woven fabric. It has the main production processes of needle punching, spunbonding, hot air or melt blowing, and it also has the equivalent of resisting liquids, filtering particles and bacteria.

Let me tell you about non-medical masks.
