ABSTRACT:
A coreless and spirally wound non-woven filter element is provided. The filter element includes at least one band of base media having a selected porosity and an interlay having a different porosity within at least one band of base media. The presence of the interlay in the filter element can create additional surface area within the contiguous construction of a filter element for filtration. This interlay can also create the ability to change direction of flow and to increase the deposition of specifically sized contaminants.
