Filter element

A filter element comprising

• a fold pack of a folded filter medium having a plurality of folds, the fold pack including:
• an inlet flow face defined by filter medium fold peaks at a raw side of the fold pack;
• an outlet flow face defined by filter medium fold valleys at a clean side of the fold pack;
• a first fold pack side at a first fold ends of the folded filter medium;
• an opposing second fold pack side at opposing second fold ends of the folded filter medium;
• wherein the fold peaks and fold valleys extend across filter medium from the first fold pack side to the second fold pack side;
• at least one frame part secured onto fold ends at the first or second fold pack side of the fold pack;
• wherein the frame part in the area of the fold valleys at fold ends has openings extending through the frame part at least on one side of the fold pack.

An air conditioning device or cabin air supply device of a motor vehicle, comprising

• a flow passage;
• a filter element arranged in the flow passage;
• wherein the filter element includes a fold pack of a folded filter medium having a plurality of folds, the fold pack including:
• an inlet flow face defined by filter medium fold peaks at a raw side of the fold pack;
• an outlet flow face defined by filter medium fold valleys at a clean side of the fold pack;
• a first fold pack side at a first fold ends of the folded filter medium;
• an opposing second fold pack side at opposing second fold ends of the folded filter medium;
• wherein the fold peaks and fold valleys extend across filter medium from the first fold pack side to the second fold pack side;
• a side strip secured onto fold ends at the first or second fold pack side of the fold pack;
• wherein the side strip that connects fold ends on at least one of the fold pack sides of the fold pack;
• wherein the fold pack has a height defined by the distance between the inlet flow face and the outlet flow face;
• wherein the side strip is connected only about a portion of the height of the fold pack therewith in such a way that the fold valleys and/or fold ridges of the fold pack are not connected with the side strip, such that liquids are permitted to pass in a passage between the not connected fold valleys and/or fold ridges and the side strip;
• wherein the filter element is mounted at a slant to the horizontal plane in the flow passage in such a way that the fold valleys of a fold pack of the filter element are slanted so that water in the fold valleys can drain, following the force of gravity, to pass in the passage between the not connected fold valleys and/or fold ridges and the side strip;
• wherein the water can pass between the fold ends and the flow passage from a raw side in front of the filter element to a clean side downstream of the filter element.
