Masks can really protect your health, you will understand after reading the introduction to mask filters!

The filter materials of protective masks are mainly divided into two categories, namely dust-proof and anti-virus. Their role is to absorb harmful aerosols, including dust, smoke, mist, poisonous gas and poisonous vapor, etc., through the filter material, and block them from being inhaled by people.
For the filter material of a good protective mask, the following three conditions should be met. One is that the filter efficiency is high when the mask is in good contact with the user's face, the other is that the breathing resistance is small, and the third is that the user feels comfortable. There are many materials for the filter material of dust-proof masks, including ordinary fabrics, animal hair, non-woven fabrics and so on. Currently very popular in the national standard is a synthetic, electrostatically treated non-woven material. Why use electrostatic treatment?
The structure of a gauze mask has poor adhesion to the human face. Many small particles that are extremely harmful to us will enter the respiratory tract to the lungs through the gap between the mask and the face. The filter material is generally some mechanical fabric. The way to achieve high dust resistance efficiency of the material is to increase the thickness, and the negative effect of increasing the thickness is to make the user feel that the breathing resistance is great and feel uncomfortable. The electrostatically treated non-woven fabric can not only block large dust particles, but also the electrostatic charge attached to its surface can absorb fine dust through electrostatic attraction, achieving high dust blocking efficiency. The thickness of the filter material is very thin, which greatly reduces the user's breathing resistance and feels comfortable, thus achieving the three necessary conditions for a good filter material we mentioned earlier. With a good filter material and a scientifically designed mask structure, a high-efficiency and high-quality mask is formed, which can make you feel convenient and comfortable to use, and can truly protect your health.
