一种梯级过滤防尘面罩
By employing a tiered filtration design combining double-layer metal fiber cloth, electrostatic cotton, and meltblown fiber cloth, the KN100 dust mask addresses the issues of high breathing resistance and short filter layer lifespan in mining environments. This achieves efficient dust interception and the reuse of the filter layer, enhancing wearing comfort and protective effectiveness.

AI Technical Summary
The existing KN100 dust mask has high breathing resistance and low wearing comfort in high-concentration dust environments such as mines, making it difficult for workers to wear it continuously, and the filter cotton layer has a short service life.
The filter uses a double-layer metal fiber cloth for tiered filtration. The primary layer intercepts large dust particles, while the electrostatic cotton and meltblown fiber cloth provide fine filtration. The self-cleaning function of the metal fiber cloth extends the service life of the filter layer.
It achieves efficient interception of all dust and fine filtration of micro-dust, reduces breathing resistance, extends the service life of the filter layer, and improves wearing comfort and protective reliability.
