The mask is composed of three layers. The inner and outer layers are non-woven fabrics, and the middle layer is melt-blown cloth called the “heart” of the mask. The three layers of cloth block dust and viruses through the principles of physical barrier and electrostatic adsorption. role.
Disinfection methods such as high temperature, alcohol, and radiation will destroy the inner structure of the melt-blown cloth, causing it to lose its filtering effect. Therefore, ordinary masks cannot be reused.
The ptfe reusable mask filter membrane adopts a surface filtration mechanism to easily remove dust. The membrane pore size is small, small and uniform, and can effectively remove dust accumulated on the surface. Washing with water or backflushing can restore performance and extend service life.
