<p>Filter media, filter elements, and method of forming filter media and filter elements are provided. The filter media and filter elements require filtered fluid to pass through filter media twice. The filter media and filter elements generally relate to fluted or similar style filter media. The filter media is formed from convoluted sheets coupled to face sheets to form first and second sets of flutes. At least one of the flute sets includes inlet and outlet seals and the other one of the flutes includes an intermediate seal interposed between the inlet and outlet seals of the other flute set. This forces the fluid to pass through the filter media at least twice.</p> |
