  "textContent": "The invention relates to a cabin air filter element for a cabin air filter for the driver's cab of agricultural and work machines, in particular with spray or spraying devices for plant protection or fertilizing agents, comprising a filter frame, a pre-filter layer, an adsorption filter layer, a fine filter layer in particular for the separation of aerosols, wherein the filter layers are substantially flowed through along a flow direction. The cabin air filter element according to the invention is characterized in that the filter element frame has a first region with a first effective cross-sectional area perpendicular to the flow direction and a second region with a second effective cross-sectional area perpendicular to the flow direction as well as a circumferential seal for separating the raw side from the clean side in the installed state, wherein the first region is arranged upstream of the seal and the second region is arranged downstream of the seal and the second effective cross-sectional area constitutes only a portion of the first effective cross-sectional area.",
