  "textContent": "The invention relates to a main filter element (22) for a filter device (10), in particular an air filter for an internal combustion engine, which can be arranged in a filter housing (12). This is to be flowed through by a fluid to be filtered. The main filter element (22) is designed as a multiple bellows filter with at least two radially nested filter bellows (32, 34), wherein at least one of the filter bellows (32, 34) is to be flowed through in the radial direction. Between the filter bellows (32, 34), a flow space (44) for the fluid is formed. This communicates with an end face of the main filter element (22), wherein each of the filter bellows (32, 34) is designed as a star filter with star-shaped arranged filter folds. On at least one end face of the main filter element (22), there is a seal (36) for sealing against a filter housing (12, 104).",
