Abstract
A method is disclosed for making a catalyzed particulate filter with high clean filtration efficiency which may include applying a catalyst material to a filter body having porous filter walls, wherein filtration material comprising filtration particles are disposed on or in or both on and in porous filter walls, and the filtration material is hydrophobic while the catalyst material is applied. A catalyzed particulate filter with high clean filtration efficiency is also disclosed wherein the filter includes porous filter walls with filtration particles disposed on or in or both on and in the porous filter walls, and catalyst material disposed on or in or both on and in the porous filter walls, and wherein the catalyst material substantially does not touch the filtration particles.
