Masks made of ptfe nanomask filter membrane can better block fine dust from entering the filter material, just like a first layer of artificial dust, achieving surface filtration (accumulated dust can be easily removed through mechanical vibration or wiping) ), the dust removal efficiency reaches 99.9%~99.999%, and even has a high dust removal efficiency for fine particles of PM2.5~PM10, which can achieve a level close to “zero emission” and meet the needs of sub-efficient, high-efficiency, and ultra-high-efficiency air filtration. filter efficiency level requirements.
