WALL FLOW HONEYCOMB FILTERS AND METHOD OF MANUFACTURE
Method of making and filtration article comprising a plugged honeycomb filter body comprising: intersecting porous walls extending an axial length in an axial direction from a proximal end to a distal end of the honeycomb filter body and defining a plurality of axial channels comprised of inlet channels, which are plugged at the distal end of the plugged honeycomb filter body, and outlet channels, which are plugged at the proximal end of the plugged honeycomb filter body, the porous walls comprising: porous ceramic base portions with a plurality of pores and an average thickness and having inlet sides and outlet sides; inlet surfaces defining the inlet channels; outlet surfaces defining the outlet channels; and treated sides comprising hydrophobic material deposits disposed at one of the inlet sides or the outlet sides of the porous ceramic base portions.
