What is the breathability and waterproof performance of ptfe reusable mask filter membrane?

PTFE reusable mask filter membrane is mainly due to its use of materials with smaller fiber diameter compared with traditional masks.

Generally speaking, the fiber diameter of the ordinary non-woven material used in our traditional masks is more than 1000 nanometers, while the fiber diameter of the PTFE membrane is between 100 and 200 nanometers, which is much smaller than the above diameter. Therefore, it can very effectively block PM2.5 in the air, as well as some viruses, bacteria and particles that are invisible to the human eye.

It is a high-tech enterprise integrating the production, research and development, and sales of polytetrafluoroethylene membranes. It has a complete set of domestically advanced production lines and a complete service system.
