What details do I need to pay attention to when wearing a mask?
- Apr 09, 2020 -

The filtering performance of the mask is mainly determined by the filter material in the middle layer. The filter material currently used is a melt-blown non-woven fabric made of polypropylene microfibers. It is light and thin, has good air permeability, and can filter the air efficiently. particulates. The filter material is not as thick as possible. The performance of the melt-blown non-woven fabrics produced by different manufacturers varies greatly, and the specific performance needs to be measured by professional equipment. Only masks containing this kind of filter material can have good filtration efficiency. If it is just ordinary needle-punched non-woven fabric and spunlace non-woven fabric, and there is no melt-blown non-woven fabric, good filtration effect cannot be achieved. In addition to good filter materials, protective masks should also have good shape design and nose clip design. The better the mask fits the wearer's face, the better the protective effect. This prevents contaminants from entering the mouth and nose through the gaps on the edges of the mask, especially on the sides of the nose. Medical surgical masks and medical protective masks can block the pollution caused by the splash of blood and body fluids, but if you really need to block the pollution of airborne particles and pathogenic microorganisms, please choose to wear a medical protective mask.
