A diesel particulate filter assembly, and methods for use of such filter assembly, including a housing having an inlet end and an outlet end, a particulate filter portion consisting essentially of mullite fibers and positioned in the housing, an array of honeycomb channels in the filter, a porous wall between adjacent channels, and an exhaust path extending through the inlet end, through the particulate filter portion and though the outlet end.
What is claimed is: 1. A method of removing particulate matter from an exhaust gas, comprising: receiving an exhaust gas into a first channel of a honeycomb porous filter; passing at least some of the exhaust gas through a wall to a second channel of the honeycomb porous filter; trapping the partic
What is claimed is: 1. A method of removing particulate matter from an exhaust gas, comprising: receiving an exhaust gas into a first channel of a honeycomb porous filter; passing at least some of the exhaust gas through a wall to a second channel of the honeycomb porous filter; trapping the particulate matter in the porous filter, the porous filter having pores at least partially defined by intertangled mullite fibers, the intertangled mullite fibers bonded into a nonwoven rigid porous matrix; and exhausting the cleaned exhaust gas from the second channel. 2. The method according to claim 1, further including the step of regenerating the walls at a temperature in the range of about 200 degrees Celsius to about 500 degrees Celsius. 3. The method according to claim 1, further including the step of regenerating the walls at a temperature in the range of 150 degrees Celsius to about 750 degrees Celsius. 4. The method according to claim 1 wherein the wall is a cylinder substantially made up of intertangled mullite fibers. 5. The method according to claim 1 wherein the wall is housed within a housing member and separates the first channel from the second channel.
