Today's protective masks are mostly disposable masks, melt blown nonwovens is mainly used as a filter layer, which is a thermoplastic and easily causes white pollution. Starting from the concept of recyclability, we have developed a new generation of microporous —— Filter film, which has good chemical stability, can be washed and disinfected, reused, and still maintain a high level of filtration efficiency.

We have developed a new generation of high-rate, low-resistance nano microporous film that can be used as mask filter materials, namely expanded polytetrafluoroethylene films (ePTFE films). The film is only 3 microns thick and consists of nodes and fibers. The network structure is used to filter fine particles by physical structure. It has become a traditional melt-blown cloth as a substitute for blocking fine dust. The surface of the microporous filter filmhas a spider-web-like microstructure, with hundreds of millions of micropores per square centimeter,  and the diameter of fiber filaments can reach the nanometer level.

In the Series 5 performance edition, we use fluorine-free super-hydrophobic technology for the outer fabric, which can prevent splashing and can withstand washing up to 100 times. The drying method does not affect the durability of the outer layer waterproof. After the new technology is processed, the outer layer fabric can still maintain a natural touch, which is unmatched by the existing technology. At the same time, the inner layer is made of antibacterial bamboo-fiber fabric, which has excellent antibacterial effect, keeps both the mask and the cavity of the nose and mouth hygroscopic, breathable, and comfortable, and also fits the face.

In the Series 7 luxury edition,we have developed a detachable and foldable three-dimensional skeleton through ergonomic design and 3D printing technology, which effectively supports and shapes three-dimensionally, which can increase the mouth and nose cavity area and increase the breathing space.
