ABSTRACT:
A honeycomb filter includes a honeycomb structure and a zeolite. The honeycomb structure has cell walls to define cells between the cell walls. The zeolite is supported on the cell walls. An amount of the zeolite is from about 80 g/L to about 150 g/L. A porosity of the cell walls is from about 55% to about 65%. A cell density in a cross section perpendicular to the longitudinal direction is from about 46.5 pcs/cm2to about 62.0 pcs/cm2. A thickness of the cell walls is from about 0.2 mm to about 0.3 mm. The cells include a large volume cell and a small volume cell. An area ratio of a cross sectional area of the large volume cell relative to a cross sectional area of the small volume cell is from about 1.4 to about 2.4.
