Abstract

The disclosure relates to an air filter assembly for cleaning an air stream for a commercial vehicle, including a pre-filter communicating with an air intake and a first fine filter which is provided downstream of the pre-filter in the direction of the air stream and, together with the pre-filter, is associated with an air filter part which extends vertically in a predetermined installation position. A redundant second fine filter, which is associated with an air filter part which extends horizontally in the predetermined installation position, follows the first fine filter in the direction of the air stream, the horizontally extending air filter part being a component of a syphon-like conduit region which rises in a curved manner in the direction of an air outlet, starting from the redundant second fine filter.
