A honeycomb filter having improved particulate capacity is provided by forming the filter from a matrix of thin interconnected porous walls defining a plurality of cells extending between opposing inlet and outlet end faces and closed near the outlet end face and, preferably, a porous outer skin surrounding the matrix of thin walls and extending between the inlet and outlet end faces of the filter. The thin walls and porous skin, if provided, have interconnected open porosity of a volume and size sufficient to enable the fluid to pass into and through the thin walls and skin to and through the outlet end face of the filter and/or to pass across the thickness of the porous skin (if provided) between the interior and exterior of the filter, while entrapping at least a significant portion of the solid particulates present in the fluid. The described filters may be formed from ceramic materials having primarily cordierite crystal phases for moderately high (up to at least 1200°C.) temperature filtering applications.

In an apparatus for removing solid particulates from fluids, a filter of honeycomb structure comprising: a matrix of thin porous interconnected walls defining an open inlet end face and an opposing outlet end face of the filter and a multiplicity of cells extending substantially longitudinally between the inlet and outlet end faces, all of the cells being open at the inlet end face and closed near the outlet end face, the thin walls having interconnected open porosity of a volume and size sufficient to enable fluid to enter and flow within the thin walls to and through the outlet end face of the filter and to prevent at least a significant portion of the solid particulates in the fluid from flowing through the thin walls to and through the outlet end face of the filter.
