Abstract

A filter arrangement for filtering the supply air of an engine, comprising a filter element with a folded filter medium, whereby the folded filter medium comprises longitudinal folds with fold walls and fold troughs, and a filter housing for receiving the filter element, whereby the filter housing comprises an upper part and a bottom part. A first insertion tongue is arranged on the upper part and a second insertion tongue is arranged on the bottom part, whereby at least one insertion tongue engages in a fold trough and whereby the insertion tongues press a fold wall between themselves is characterized in that, in regard to the problem of improving the sealing concept of the prior art and of preventing the passage of dust from the raw air side to the clean air side with a high degree of reliability, the filter element comprises side strips manufactured from a compressible material that can be compressed to at least 80% of its thickness in the unloaded state.
