Evaluating the protective performance of masks mainly focuses on two aspects: first, the quality of the material of the mask itself, the filtration efficiency of the filter elements, and the durability within the validity period of use.
The second is the adaptability of the mask to the wearer’s face.
Therefore, excellent filter materials are very important. The editor here recommends disposable medical mask filter materials to everyone.
Disposable medical mask filter material is mainly due to its use of materials with smaller fiber diameters compared with traditional masks.
Generally speaking, the fiber diameter of the ordinary non-woven material used in our traditional masks is more than 1000 nanometers, while the fiber diameter of the PTFE membrane is between 100 and 200 nanometers, which is much smaller than the above diameter. Therefore, it can very effectively block PM2.5 in the air, as well as some viruses, bacteria and particles that are invisible to the human eye.
? It has a complete set of domestic advanced production equipment and adopts advanced production technology. Its products have passed ISO9001 quality management system certification. The testing standards strictly follow the EU standard EN1822. Membrane products are tested using the MPPS method.
