Descripción del producto

The efficiency of respirator is based on its barrier efficiency to fine dust, especially to respirable dust under 2.5 μ M. Because this particle size dust can directly enter the alveoli, which has the greatest impact on human health.

Gauze mask, its principle of dust prevention is mechanical filtering, that is, when the dust collides with gauze, through layer upon layer of barrier, some large particles of dust are blocked in the sand cloth. For some fine dust, especially dust less than 2.5 microns, it will pass through the mesh of gauze and enter the respiratory system. Dust mask is composed of filter material active carbon fiber felt pad or non-woven fabric. The respirable dust less than 2.5 μ m is blocked in the process of passing through the filter material and plays the role of filtering air.
