Abstract: A filter element includes a single seamless media pack having first and second opposite ends and first and second lateral sides extending between the first and second ends. The media pack also has pleats extending between the first and second ends and a first cross-section defined between the first and second lateral sides. The first cross-section having at least one outward projection that defines an internal radius of at least ¼ inch wherein a plurality of pleats of the media pack are fanned around the internal radius. A first end cap is secured to the first end of the media pack while a second end cap secured to the second end of the media pack. Additionally, a frame member is secured to the first end cap, second end cap, the first lateral side, and the second lateral side. A pre-filter is usable with described filter arrangements.
