The invention relates to a gas filter structure for filtering particulate-laden gases, of the honeycomb type and comprising an assembly of longitudinal adjacent channels of mutually parallel axes separated by porous filtering walls, said channels being alternately blocked off at one or the other of the ends of the structure so as to define inlet channels and outlet channels for the gas to be filtered and so as to force said gas to pass through the porous walls separating the inlet and outlet channels, said structure being characterized in that the inlet and outlet channels share between them at least one wall of constant average thickness d over the entire length of the filter structure, in that the inlet or outlet channels share between them at least one wall of constant average thickness e over the entire length of the filter structure and in that the e/d ratio is strictly greater than 1.
