Nowadays, there are hundreds of masks produced. Among so many mask manufacturers, what aspects should be paid attention to when choosing a good mask? Today we will explain.
1. Degree of tightness
The anti-side leakage design of the mask is to prevent air from passing through the gap between the mask and the face, and not being inhaled through the mask filter. Technical considerations. When the shape of the mask is not close to the human face, dangerous objects in the air will leak in from the non-closed place and enter the human respiratory tract. So, even if you choose a mask with the best filter material, it cannot protect your health. At present, the double-core nose bridge mask has a very good fit and can minimize the air passage rate.
2. Dust blocking efficiency
The dust blocking efficiency of a mask is based on its blocking efficiency for fine dust, especially for respirable dust below 2.5 microns. Because dust of this particle size can directly enter the alveoli, it has the greatest impact on human health. It is recommended to choose non-woven masks, especially KN95 masks (5mm nose wire), those respirable dust less than 2.5 microns can be filtered out in the process of passing through this filter material.
3. Comfortable to wear
In this way, workers will be willing to insist on wearing them in the workplace and improve their work efficiency. The maintenance-free masks in foreign countries do not need to be cleaned or replaced. When the dust barrier is saturated or the mask is damaged, it will be discarded. This not only ensures the hygiene of the mask, but also saves the workers the time and energy to maintain the mask.
The KN95 mask using 5mm nose wire is soft and comfortable. It fits well on the human face. It has a beautiful appearance and is comfortable to wear.
