Filter elements and methods of manufacturing filter elements are provided. Examples of filter elements include a media pack and a frame attached thereto. In one example, the frame includes a side panel that is or includes a foldable portion. The foldable portion is folded away from the media pack and an adhesive is located therebetween during assembly. In other examples, a media support member is provided that includes at least one side support panel that supports a side of the media pack. A portion of the side support member is positioned between adjacent pleat panels of the media pack.

Filter frame with foldable sealing flap

In an embodiment, a filter media support frame for supporting first and second panels of filter media in a spaced apart relation is provided. The filter media support frame includes a first panel support, a second panel support and a connection portion. The first panel support has a first inner side and a first outer side. The second panel support has a second inner side and a second outer side. The second inner side faces the first panel support. The first connection portion hingedly connects to the first panel support by a first hinge portion and hingedly connects to the second panel support by a second hinge portion. Filter elements including the filter media support road filter media are provided.

Filter with shield features

An air filter element and air filter system are provided. The filter element has an annular gasket that has multiple portions. A first portion provides axial sealing while a second portion provides only radially sealing. The filter element includes a frame with a radial abutment for engagement with a tooth on a filter housing for providing lateral biasing to the portion of the gasket that provides radial sealing.

Gasket and frame assembly for air filter

Filters and filter assemblies including one or more shield elements to protect the filter media of the filters during installation of the filters into a filter housing of the filter assembly are provided. A filter includes first and second media packs, a housing seal system, a handle and a shield element. Filter media packs extend from a first end to a second end in a diverging manner. The first end has a length dimension and a width dimension that extend transversely. A shield element projects over the first and second media packs at the first end a span in the width direction of at least 40% of the width dimension defined by the first and second media packs and projecting a span in the length direction of at least 5% of the length dimension defined by the first end.

A filter element and multi-component holding assembly for a filter element is provided. The filter element includes first and second media panels, a support frame, a base frame and first and second end cap structures. Each filter media panel defines first, second, third and fourth sides. The first and second sides extend between the third and fourth sides. The support frame maintains the first and second filter media panels in a spaced orientation forming a cavity therebetween. The base frame defines a first opening in fluid communication with the cavity. The first end cap structure seals the third side of the first and second filter media panels and the second end cap structure seals the fourth side of the first and second filter media panels. The base frame has a first portion captured in the first end cap structure and a second portion captured in the second end cap structure.
