A filter unit for removing particles from an air or gas flow, comprising:
- a filter body having a front side, a rear side, and an edge side between the front side and the rear side, and
- an edge strip arranged on the edge side, which edge strip extends at least the height of the edge side and at least the length of the edge side, for providing the edge side with a mounting support,
- wherein the edge strip comprises a foamed thermoplastic material, which is molded to the edge side of the filter body such that the edge strip thereby is formed and fastened directly to the edge side of the filter body, and such that the edge side is embedded in the edge strip for providing the edge side with a sealing against air leakage,
- wherein the foamed thermoplastic material is molded to the edge side of the filter body, such that the edge strip in its cross-section is U-shaped, and
- wherein the amount of gas in the foamed thermoplastic material is 40% to 80% by volume.
