Adhesive is provided between the fluted sheet and the facing sheet at the first end or the second end, and wherein the fluted sheet and the facing sheet are pushed together and adhered together at the location of the adhesive to provide a seal between the fluted sheet and the facing sheet. At least 25% of the flutes of the fluted sheet comprise at least one ridge extending along at least 50% of the flute length between adjacent peaks. Filtration media packs, filter elements, and methods for forming a single facer media are provided.
