The invention relates to a particle-loaded gas filtration structure, of the honeycomb type, comprising a set of longitudinal adjacent channels of mutually parallel axes separated by porous filtering walls, in which: each outlet has a common wall with six input channels, each common wall constituting one side of said output channel, each output channel consists of six sides of width a substantially identical, so as to form a substantially hexagonal and regular section channel at least two adjacent sides of each input channel have a different width, at least two input channels, sharing a wall with the same output channel, share with each other a common wall of width b and in which the ratio of widths b / a is greater than 1 and less than 13. |
