Why are ptfe reusable mask filters popular?
The prevention and control of the new coronavirus pneumonia epidemic has become normalized, and masks have become a standard feature of daily life.
However, corresponding “mask questions” have also arisen, such as when to take off and when to wear masks, how to store masks, and whether disposable masks can be replaced by reusable masks, etc.
The PTFE reusable mask filter membrane made by mechanically stretching PTFE material can withstand repeated disinfection treatment with boiling water, alcohol, 84 disinfectant, etc., and its performance can still remain stable.
It has the characteristics of “high breathability + water impermeability”. For small particles with a diameter of 75 nanometers (0.075 microns), its filtration performance exceeds 95%, which means it meets the standards of N95 masks.
