ABSTRACT:
A filter is disclosed which employes two panels of single-faced corrugated paperboard cut into strips or runs, each strip or run glued in an overlaying fashion relative to the one juxtaposed thereto so that the longitudinal axis defined by each corrugation, lies at an angle relative to the plane of the panel of between 45.degree. and 75.degree.. Two such panels are reversingly juxtaposed into an abutting relationship in one embodiment, and against a medial gauze media in another embodiment, to form a novel filter media suitable as a paint arrestor, coating arrestor or the like.
