Compared with gauze masks and non-woven masks, non-woven masks have better dust-proof effects. In terms of mask material alone, the dustproof effect of gauze masks is much worse. The filter material of non-woven masks is electrostatically treated to block large-diameter particles and has excellent protection against small particles. The filter materials of gauze masks are all mechanical fabrics. , It can only protect large-diameter particles and cannot be used as a professional dust mask.
 
There are many materials for the filter material of dust masks, including ordinary fabrics, animal hair, non-woven fabrics and so on. It is a synthetic, electrostatically treated non-woven material that is very popular in the world. At present, well-known brands such as 3M dust masks and Shigematsu masks are highly efficient anti-smog masks developed using this technology.

What are the advantages of dust masks made of electrostatically treated filter materials?

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 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 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. However, the thickness of the filter material is very thin, which greatly reduces the user's breathing resistance and feels comfortable. With a good filter material and a scientifically designed mask structure, it constitutes a high-efficiency and high-quality mask, which can make you feel convenient and comfortable to use, and can truly protect your health.

For the filter material of a good dust mask, the following three conditions should be met:

1. The filtering efficiency is high when the mask is in good contact with the user's face.

2. The filter material has low breathing resistance.

3. The user feels comfortable.
