Some problems can't be ignored when choosing masks!

We can't ignore some problems when we choose masks. Here's a brief introduction from the manufacturer of masks:

1、Filtering effect

The dust blocking efficiency of gauze mask is based on its blocking efficiency for small dust, especially for respiratory dust less than 2.5 microns. Because this kind of particle size dust can directly enter the alveoli, which has a great impact on human health. The filter material of the dust mask is activated carbon fiber pad or non-woven fabric, and the inhalable dust less than 2.5 μ m 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 inhaled through the gap between gauze mask and human face without filtering. Air is like a stream of water, flowing where there is little resistance. When the shape of the gauze mask is not suitable for the face, dangerous substances in the air will also enter the human respiratory tract.

3、Breathable comfort

Many masks adopt arch shape, which can not only ensure a good fit with the face shape, but also maintain a certain space at the mouth and nose, and wear comfortably.

If the medical gauze mask has good air permeability, it can be worn comfortably by both medical staff and other wearers.
