L'invention concerne un soufflet de filtration (12), en particulier pour un système de filtre à air, composé d'un milieu filtrant (14) plié en zigzag, des arêtes de pliage (26) s'étendant chacune entre les surfaces (20a, 20b) opposées d'arêtes frontales faites d'arêtes frontales (22a, 22b), et dans chaque cas un pli frontal (24) présentant une arête de pliage (26) et un bord frontal (30) libre opposé étant agencé sur les faces frontales (36, 38) opposées et les arêtes de pliage (26) étant situées sur une surface côté fluide brut (44) dans l'état d'utilisation monté et une surface côté fluide propre (46) opposée, dans l'état d'utilisation monté. Un passage (50) est constitué entre la surface côté fluide brut (44) et la surface côté fluide propre (46), lequel comprend une ouverture côté fluide brut (60) présentant une section transversale côté fluide brut (54) et une ouverture côté fluide propre (62) présentant une section transversale côté fluide propre (56), l'une des sections transversales (54, 56), dans le cas d'une projection des ouvertures (60, 62) les unes sur les autres, étant située au moins en partie à l'extérieur de l'autre section transversale (56, 54). L'invention concerne en outre un élément filtre (10) comportant un soufflet de filtration (12) de ce type et l'utilisation de l'élément filtre (10) comme filtre à air plat, en particulier comme filtre à air plat d'un moteur à combustion interne, et un système de filtration (100) équipé d'un élément filtre (12) remplaçable de ce type.
