Abstract
A method of manufacturing a media assembly comprises winding a filter media about a center axis into a media roll and cutting the media roll along at least two cut lines and into at least two media packs of at least two media assemblies. The media roll is cut along at least one plane that is parallel to the center axis.

A method of manufacturing a media assembly, the method comprising:
- winding a filter media about a center axis into a media roll;
- and
- cutting the media roll along at least two cut lines and into at least two media packs of at least two media assemblies, the media roll being cut along at least one plane that is parallel to the center axis.
A media assembly comprising:
- a media pack comprising a plurality of layers of filter media, the media pack defining an inlet flow face, an outlet flow face, a first side wall, a second side wall, a radially inner edge, and a radially outer edge, the first side wall and the second side wall each extending axially between the inlet flow face and the outlet flow face and radially between the radially inner edge and the radially outer edge;
- a first side panel positioned along and forming a seal with the first side wall such that fluid entering through the inlet flow face cannot exit the media pack through the first side wall;
- and
- a second side panel positioned along and forming a seal with the second side wall such that fluid entering through the inlet flow face cannot exit the media pack through the second side wall,
- the media pack being formed by winding the filter media around a center axis into a media roll and cutting the media roll along at least two cut lines to form the first side wall and the second side wall.
