Zusammenfassung:	A filtering layer for an air purification device, comprising a first filtering layer (301) and a second filtering layer (302). The first filtering layer (301) and the second filtering layer (302) are provided with wavy fold straight lines formed by continuously forward and backward folding a fiber material containing a flocculent structure. The texture of the fold straight lines of the first filtering layer (301) and the texture of the fold straight lines of the second filtering layer (302) are arranged at different angles or directions. Une couche filtrante pour un dispositif de purification d'air, comprenant une première couche filtrante (301) et une seconde couche filtrante (302). La première couche filtrante (301) et la seconde couche filtrante (302) sont pourvues de lignes droites de pliage ondulées formées par pliage vers l'avant et vers l'arrière en continu d'un matériau fibreux contenant une structure floculante. La texture des lignes droites de pliage de la première couche de filtrage (301) et la tex
