The ptfe reusable mask filter membrane can filter more than 95% of bacteria and PM2.5 particles in the air, reaching the filtration standard of KN95 masks.
The extremely high porosity and ultra-thin thickness of <5μm give it better air permeability, small breathing resistance, comfortable wearing, and no attenuation of the interception rate due to moisture in the exhaled breath.
The filtration efficiency of the melt-blown cloth itself is only 30%. It can reach more than 80% after electret treatment and charging. Therefore, the melt-blown cloth mask is disposable and has an aging limit. It will be damaged if washed or stored for too long. Causes the charge to disappear and reduces the filtering effect.
It is a polytetrafluoroethylene material manufacturer specializing in R&D, production and sales.
Has a complete set of domestically advanced production lines and a complete service system.
