Abstract
An air filter insert including at least one filter element () and a seal () extending along outer edges of one side of the filter insert () and via which the filter insert is sealingly seated against housing sections () of a surrounding filter housing. The filter insert () is configured such that the air can easily flow into or out of the structural space on the one side of the filter element with a minimum pressure drop. The filter insert () may be at least partially covered on the inflow and/or discharge side by a semi-permeable component (), which at least partially equalizes the pressure distribution in the air stream. The filter element also may be supported in the filter housing via a circumferential seal () which is disposed on the outer periphery of the filter insert and received in a seat () of a lower housing section (), and a sealing pressure is applied by an upper housing section (), so that the overall height of the filter insert is decreased and the surface of the seal () is substantially co-planar with the surface of the filter insert ().
