Channel flow filtration media possessing high efficiency and low pressure drop is formed from a plurality of filtration layers at least some of which include a multi-dimensional channel pattern having a plurality of continuous, tortuous channels and a multi-dimensional edge at each end of the plurality of channels formed therein. The filtration medium is configured as a stack with the multi-dimensional edge of the channel pattern forming a plurality of inlets open through a first face of the stack, a plurality of outlets open through a second face of the stack, and a corresponding plurality of disruptive fluid pathways passing from the inlets through the stack to the outlets. The filtration layers may be formed from a non-woven material, such as a carbon loaded multi-layer BMF web capable of adsorption of undesired vapors and odors from a fluid.
