KN95 and N95 masks are the best type 2 masks. We often see medical and non-medical words printed on the type 2 masks. So what are the differences between medical masks and non-medical masks? As a professional medical product manufacturer, I will introduce it to everyone.

What is the difference between medical and non-medical masks in KN95 / N95 masks
 

The main difference is that the outer surface of medical type masks is treated with hydrophobic treatment. The medical surgical masks GB19083-2010 and YY0469-2011 clearly put forward the requirement of "synthetic blood penetration", and the parameter index of "surface moisture resistance" clearly defines the medical protective mask Protective effect on blood and other fluids. In general, it is like water droplets will roll off on the lotus leaf. The liquid cannot penetrate on the surface of the mask, which can prevent medical staff from often touching alcohol and blood to prevent it from penetrating quickly; instead of medical type KN95 The / N95 mask does not undergo this special treatment.

The most protective function of KN95 and N95 protective masks is the filter layer. This filter layer uses polypropylene meltblown microfiber electret material. The outer surface of the mask has not been treated with hydrophobic treatment. Contact with water and alcohol during application will destroy the material. Structure, greatly reducing the filtering effect. What's more, the blood often contains bacteria and viruses, and the application of the hospital determines that medical personnel are most likely to be exposed to the patient's blood environment. Therefore, hydrophobic treatment on the surface of medical masks is essential. However, the probability of ordinary people encountering alcohol and blood is not high. As long as the masks are changed regularly, it will not hurt the outside without this treatment.
