Filter for air and intended for use in wet environment of folded filter material (1) that is held together by glue strips (2,3) on the front and rear side of the filter material. The glue strings on the front side of the filter are interrupted at the bottom of the folds turned forwards so that transport channels (4) for water (5) are obtained at each forwards turned fold. Furthermore the filter folds are oriented vertically to facilitate for the water to run off.

[ What is claimed is:] [1.] An air filter of folded filter material that is held together by glue strings on a first surface and a second surface of the filter material, wherein the glue strings on the first surface of the filter material are discontinuously positioned on the first surface of the filter material such that when the filter material is folded into a zigzag configuration awater transport channel uninterrupted by glue is formed between the zigzag configuration and the glue string on the first surface of the filter material.
