Can I take off my mask in March 2023?

According to the news, masks can be taken off in March after the Spring Festival, because the resistance of people after the Spring Festival has become stronger, and the virus toxicity has also weakened after the spring blossoms. At this time, you can take off your mask.

In the summer of 2023, it should be possible to take off the mask, because the weather is hot and the virus has a short survival time. It should be possible to take off the mask after the epidemic is basically over, but it is suitable for the crowd, and some people can take care to defend themselves with masks.

Mask filter material:

A good filter material for protective mask should meet the following three conditions: first, the filter efficiency is high when the mask is in good contact with the user's face; Second, the respiratory resistance is low; Third, users feel comfortable. There are many kinds of filter materials for dust masks, including ordinary fabrics, animal hair, non-woven fabrics and so on. An activated carbon felt material is very popular in the national standard.

The structure of the mask is not close to the human face. Many harmful fine particles will enter the respiratory tract and lungs through the gap between the mask and the face. The filter material of the mask is usually some mechanical fabrics. The way to achieve high dust resistance is to increase the thickness. The negative effect of increasing the thickness is to make users feel great respiratory resistance and uncomfortable.

After electrostatic treatment, non-woven fabrics can not only block larger dust particles, but also adsorb fine dust through electrostatic attraction, thus achieving higher dust blocking efficiency. However, the thickness of the filter material is very thin, which greatly reduces the user's respiratory resistance and meets the three necessary conditions for a good filter material. Through the scientifically designed mask structure, an efficient and high-quality mask is formed.
