Filter assemblies and elements utilizing multilayered and wrapped filter media

A filter element, comprising:

• a core having a non-circular core cross-sectional shape;
• and
• a filter media pack comprising a plurality of filter media layers stacked on an outer periphery of the core such that the filter media pack has a filter media pack cross-sectional shape that corresponds to the non-circular core cross-sectional shape, an edge of a first filter media layer of the plurality of filter media layers is aligned with a corresponding edge of a second filter media layer of the plurality of filter media layers,
• wherein the filter media pack includes a plurality of sidewalls, and wherein at least one sidewall of the plurality of sidewalls is formed by corresponding edges of the plurality of filter media layers to define a curvature.

A filter element, comprising:

• a core having a non-circular core cross-sectional shape, the core comprising:
• a central shaft extending from a first shaft end to a second shaft end;
• and
• a plurality of circumferential ribs each protruding radially from the central shaft;
• and
• a filter media pack comprising a plurality of filter media layers stacked on an outer periphery of the core such that the filter media pack has a filter media pack cross-sectional shape that corresponds to the non-circular core cross-sectional shape.
