We ca n’t ignore some problems when choosing a mask. Here are some mask manufacturers to introduce to you:
First, the filtering effect
The dust-blocking efficiency of gauze masks is based on its ability to block fine dust, especially respiratory dust less than 2.5 microns. Because this kind of granular dust can directly enter the alveoli, it has a great impact on human health. The dustproof mask has a filter material of activated carbon fiber mat or non-woven fabric, and respirable dust smaller than 2.5 microns passes through the filter material.
Second, the degree of tightness
The anti-side leakage design of the gauze mask is a technical requirement to prevent air from being sucked in through the gap between the gauze mask and the human face without filtering. Air is like water flowing to a place with little resistance. When the shape of the gauze mask is not suitable for the face, dangerous substances in the air can also enter the human respiratory tract.
Three, breathable and comfortable
Many masks are arched, which can not only ensure a good fit with the face shape, but also maintain a certain space at the mouth and nose for comfortable wearing.
If the medical gauze mask has good breathability, both the medical staff and other wearers can wear the mask more comfortably.
