Mask Filter Material

- Apr 04, 2020-

For the filter material of a good protective mask, the following three conditions should be met. One is that the filtering efficiency is high when the mask is in good contact with the user's face, the second is that the breathing resistance is small, and the third is that the user feels comfortable. There are many kinds of dust mask material, including ordinary fabric, animal hair, non-woven fabric, etc. Very popular in the national standard is an activated carbon felt material.

The structure of the gauze mask is poorly adhered to the human face. Many fine particles that are extremely harmful to us will enter the respiratory tract to the lungs through the gap between the mask and the face. Its filter material is generally some mechanical fabric. This filter The only way to achieve high dust blocking efficiency is to increase the thickness, and the negative effect of increasing the thickness is to make the user feel great resistance to breathing and feel uncomfortable. And the non-woven fabric treated with static electricity can not only block large dust particles, but also the electrostatic charge attached to its surface can attract fine dust by electrostatic attraction, and achieve high dust blocking efficiency. The thickness of the filter material is very thin, which greatly reduces the user's breathing resistance and feels comfortable, thereby achieving the three necessary conditions of the good filter material we mentioned earlier. With good filter material and scientifically designed mask structure, it constitutes an efficient and high-quality mask.
