Abstract: An air filter comprising a sheet of filter material folded in a zig-zag configuration. A hardenable material is dispensed in a flowable state onto the sheet. The hardenable material has a varying thickness such that upon hardening, it holds the folds of the sheet apart in a selected orientation. The hardenable material may comprise glue to also secure the folds together. An air penetrable sheet can be secured to the fold edges at one or both sides of the filter.

Abstract: A filter is made by the folding of a filter media to pleats after the application of strings of glue thereon and the glue serves as distance elements and fixing for the filter media. The glue contains an expandable filler, that when heated expands to a larger size that is then permanent. When the glue has set the filter is heated and the filler expands and expands the filter pleats.
