For a mask to have a certain comfort, it must have a certain ventilation function. In theory, the difference between the ventilation function of a mask and the filtering power of the mask has a certain correlation. When the breathing function of the mask is extremely poor, the mask itself blocks the entry of foreign substances into the mask, and then plays a protective effect and does not depend on the filtering power of the mask(Nurse Face Mask Factory), but it also has the lowest comfort level and is not suitable for human wear. When the breathability of the mask is good, the material exchange in the surface of the mask is more frequent, which requires higher filtering efficiency of the mask, so as to satisfy the high-frequency material exchange, the mask can filter out the harmfulness in the air to the maximum limit Substances enter the human body, thereby providing a protective effect. The ventilation function of the mask and the filtering power must have a good matching degree in order to play a very good protective effect, and to establish a model between the ventilation function of the mask and the filtering power, it is particularly necessary to find the relationship between the two.
