Abstract
A filter element includes a filter media having an array of filter media panel members which are oriented at an angle of about 45° with respect to the air stream and are spaced so that the upstream edges of the panels overlap the downstream edges. Consequently, the air stream must pass through two panel members before exiting the filter element. The filter element may also include a secondary filter media in the form of a mat disposed over the downstream edges of the panel members. The filter element is used for filtering cabin air for vehicles or for other similar purposes as well as for filtering engine combustion air.

A filter media configuration for a filter element having a frame, wherein the filter media configuration filters a stream of gas moving transversely with respect to an opening in the frame in which a filter media is disposed in order to remove particulates from the stream, the filter media comprising:
- an array of filter media panels having upstream and downstream filter media faces defined within first and second ends and upstream and downstream edges;
- supports mounting the filter panels in the frame at an angle with respect to the air stream and with a spacing sufficient to overlap the upstream edges of single filter media panels with the downstream edges of an adjacent single filter media panels, whereby air impinging on one filter panel and passing therethrough in the direction of the air stream impinges on and passes through another filter panel before exiting the filter media.
A filter element adapted to filter an air stream flowing in a selected direction comprising:
- a frame having an opening therethrough adapted to extend transversely to the direction of the air stream;
- a first filter media disposed in the frame, the first filter media comprising an array of filter media panels having upstream and downstream filter media faces defined within first and second ends and upstream and downstream edges;
- the filter media panels being mounted in the frame at an angle and with a spacing sufficient to overlap the upstream edges single filter media panels with the downstream edges of adjacent single filter media panels whereby air impinging on one filter panel and passing therethrough in the direction of the air stream impinges and passes through another filter panel before exiting the filter media;
- and
- a second filter media mounted by the frame downstream of the first filter media.
