摘要： A filter core (120) includes a tubular body (170) that has a first end (180) and a second end (190). The tubular body includes a plurality of surface features (230) spaced longitudinally along the tubular body between the first and second ends. Each of the surface features includes a first portion (260) for flow area and a second portion (270) for bridging across an opening for strength.
