The present invention relates to a structure for filtering gas filled with particles, the honeycomb type, comprising an assembly of longitudinal adjacent channels having parallel axes separated by a porous filtration wall, each outlet channel having six inlets. A wall having a common wall with the channel, each common wall forming a face of the outlet channel, each outlet channel comprising six faces having substantially the same width (a) and having a substantially regular hexagonal cross section. Wherein two or more adjacent surfaces of each inlet channel have different widths, and two or more inlet channels sharing a wall with the same outlet channel share a common wall having a width b, where the ratio of widths (b) / a) is equal to 1 |
