How shall you select FFP2 masks?

First, the dust resistance efficiency of the mask should be high. The dust suppression efficiency of a mask is based on its effect on fine dust, especially on 5 μ The dust suppression efficiency of the respirable dust below 5 m is standard. The general gauze mask, its dust resistance principle is mechanical filtering, that is, when the dust collides with the gauze, through a layer of barrier, some large particles of dust are blocked in the gauze. However, fine dust, especially less than 5 μ M of dust, will pass through the mesh of gauze, into the respiratory system. There are some anti particulate masks on the market, whose filter media are made of fibers charged with permanent static electricity, those less than 5 μ M of respirable dust in the process of passing through the filter material, it will be attracted by static electricity and adsorbed on the filter material, really play the role of dust resistance.


Second, the mask and the face shape are close to each other. When the mask is not close to the face, the dust in the air will enter the respiratory tract from the gap around the mask. Therefore, people should choose the anti particle mask suitable for their own face shape and wear it correctly.


Third: comfortable to wear, including small respiratory resistance, light weight, hygienic to wear, convenient maintenance, such as wearing arched anti particle mask.
