How To Choose Face Mask

I believe everyone is aware of the harm of smog, and it has always been one of the key topics of the National People's Congress. Of course, this is to be discussed and resolved at the national leadership level. Our little people's response is undoubtedly to go out wearing masks. Of course, there are some tricks to wearing a mask. There are many kinds of mouthpieces, and each has its own function.

1. Dust blocking efficiency

The dust blocking efficiency of the mask is based on its blocking efficiency against fine dust and respiratory dust below 25 microns. Because dust of this particle size can directly enter the alveoli, it has the greatest impact on human health. Dust Mask, its filter material is composed of activated carbon fiber felt pad or non-woven fabric, and the respirable dust smaller than 25 microns passes through this filter material.

2. the degree of tightness

The anti-side leakage design of the mask is to prevent the air from being inhaled through the gap between the mask and the human face without being inhaled through filtering. Air is like water, where there is less resistance, it flows first. When the shape of the mask does not fit closely with the face, the dangerous substances in the air will leak from the non-fitted place and enter the respiratory tract of the person. So, even if you choose a mask with the best filter material. Nor can your health be guaranteed. Many foreign regulations and standards stipulate that workers should regularly test the tightness of masks. target
The purpose is to ensure that workers choose the right size mask and wear the mask according to the correct steps.

3. Comfortable to wear

In this way, workers will be willing to stick to wearing them in the workplace and improve their work efficiency. The current foreign maintenance-free masks do not need to be cleaned or replaced. When the dust resistance is saturated or the mask is damaged, it is discarded, which not only ensures the hygiene of the mask, but also saves the time and energy of workers to maintain the mask. And many masks are in the shape of an arch, which can not only ensure a good fit with the shape of the face, but also retain a certain space at the mouth and nose, making it comfortable to wear.
