The invention relates to an intake arrangement ( ) for the combustion air ( ) of an internal combustion engine ( ) of a handheld portable work apparatus ( ), such as a cutoff machine, motor-driven chain saw or the like. An air filter ( ) is provided for purifying the combustion air ( ). Dust-laden combustion air is directed onto the air filter via openings ( ) of a filter housing ( ). The combustion air ( ) is purified by the air filter ( ) and is drawn by suction by the engine ( ) via an intake pipe ( ) of a carburetor ( ). A carrier airflow ( ) is provided in a flow channel ( ) for continuously or intermittently transporting away dust ( ) deposited on the air filter ( ). The combustion air ( ) and the carrier airflow ( ) are spatially separated via a discharge tube ( ). In this way, a minimization of the dust load of the air filter ( ) is ensured on the one hand and a continuous transport away of the dust ( ) from the air filter ( ) is ensured on the other hand. The removal transport of the dust ( ) ensures continuous operation of the work apparatus ( ).
