A filter comprising: first and second filter media packs (702, 704) extending from a first end (716, 718) to a second end (712, 714), the first end having a length dimension and a width dimension that extend transversely, the width dimension being defined by the first and second media packs (702, 704), the first and second filter media packs converging at the first end (716, 718) and diverging when moving away from the first end toward the second end (712, 714) to define an air flow cavity therebetween; a housing seal system at the second end (712, 714); a handle at the first end (716, 718); a shield element (777, 781, 783) projecting at the first end (716, 718) over the first and second media packs (702, 704) a span in the width direction of at least 40% of the width dimension defined by the first and second media packs (702, 704) and projecting a span in the length direction of at least 5% of the length dimension defined by the first end; and a bridge element at the first end (716, 718) spanning across the first and second media packs (702, 704) along the width dimension less than the width dimension of the first end, characterized in that: the shield element (777, 781, 783) comprises a first wing panel and a second wing panel, the first and second wing panels extending outward from the bridge element along the width dimension in opposite directions such that the first wing panel extends over the first filter media pack to a farther extent than the bridge element and the second wing panel extends over the second media pack to a farther extent than the bridge element, the first and second wing panels extending along the length dimension less than the bridge element extends along the length dimension. first and second filter media packs (702, 704) extending from a first end (716, 718) to a second end (712, 714), the first end having a length dimension and a width dimension that extend transversely, the width dimension being defined by the first and second media packs (702, 704), the first and second filter media packs converging at the first end (716, 718) and diverging when moving away from the first end toward the second end (712, 714) to define an air flow cavity therebetween; a housing seal system at the second end (712, 714); a handle at the first end (716, 718); a shield element (777, 781, 783) projecting at the first end (716, 718) over the first and second media packs (702, 704) a span in the width direction of at least 40% of the width dimension defined by the first and second media packs (702, 704) and projecting a span in the length direction of at least 5% of the length dimension defined by the first end; and a bridge element at the first end (716, 718) spanning across the first and second media packs (702, 704) along the width dimension less than the width dimension of the first end, characterized in that: the shield element (777, 781, 783) comprises a first wing panel and a second wing panel, the first and second wing panels extending outward from the bridge element along the width dimension in opposite directions such that the first wing panel extends over the first filter media pack to a farther extent than the bridge element and the second wing panel extends over the second media pack to a farther extent than the bridge element, the first and second wing panels extending along the length dimension less than the bridge element extends along the length dimension.
