The present utility model discloses a multi-layer air purifying filter, including a square grid disposed on an outer layer, and a cellular grid sandwiched between two square grids, a layer of fiber cloth including activated carbon arranged between the square grid and the cellular grid, said cellular grid provided with a fiber mesh and a layer of molecular sieve. The first square grid according to the present utility model is provided with fiber mesh used to filter filamentous dust. The cellular grid containing the fiber and the layer of molecular sieve can absorb water, and filter methanol, ethanol, hydrogen sulfide, sulfur dioxide, ethylene, propylene and other harmful substances. The black activated carbon fiber cloth has an excellent effect of sterilizing and removing harmful chemicals. The product as a whole plays an effect of multi-layer filtering, and improving the efficiency of air purification. In addition, the product has a wide application, for example, which is used in a variety of air purification device, and cleaning human living space including car interior space.本新型公開了一種多層空氣淨化過濾器,包括設置在外層的方格網以及夾在兩個方格網之間的蜂窩網,方格網與蜂窩網之間設置有包含活性炭的纖維布層,所述蜂窩網內設置有纖維網以及分子篩層。本新型的第一層方格網含有纖維網,可以先過濾絲狀灰塵。含有纖維網及分子篩層的蜂窩網能吸附水,過濾甲醇,乙醇,硫化氫,二氧化硫,乙烯,丙烯等對人體有害物質。黑色活性炭纖維布具有極佳的殺菌去除有害化學物質的作用。產品整體起到多層過濾的功效,大大提高了空氣淨化效率,而且用途廣泛,可用於各種空氣淨化設備,淨化人類生活空間場所,包括小車內部空間。61‧‧‧上端蓋62‧‧‧下端蓋
