There are a few things we cannot ignore when choosing a mask. Here are some of them:

1. Filtering effect

The dust blocking efficiency of gauze respirators is based on their efficiency against fine dust, especially absorbent dust less than 2.5 microns. Because of this granularity of dust can be directly into the Alveoli, has a great impact on human health. The filter material of the dust-proof mask is activated carbon fiber mat or non-woven cloth, and the inhalable dust less than 2.5 microns passes through the filter material.

2. Degree of tightness

The anti-side leakage design of gauze mask is a technical requirement to prevent air from being sucked in without filtering through the gap between gauze mask and human face. Air is like water flowing where there is little resistance. When gauze masks are not fit the face, dangerous substances in the air can also enter the airways.

3. Breathable Comfort

Many masks are arch-shaped which not only ensures fit to the face shape, but also keeps a certain space in the nose and mouth for comfortable wearing.

If the medical mask has good air permeability. Both medical staff and other wearers are comfortable with the masks.
