Abstract

The invention relates to a fluid filter (10) for filtering a fluid, in particular air, comprising a filter housing (12) having a central support tube (22) which extends along a longitudinal axis (16) of the filter housing (12) within the filter housing (12) and a primary filter element (24) arranged inside the filter housing (12) in an exchangeable manner. There is a secondary filter element (26) positioned inside the filter housing (12) which serves as a safety-element during a replacement of the primary filter element (24). A sealing between a first end portion of the secondary filter element (26) and the filter housing (12) is effected partially or solely by the filter medium (28) of the secondary filter element (26). The first end portion of the secondary filter element may engage in a groove-shaped retaining structure of the filter housing (12). The invention further relates to a secondary filter element (26) for such a fluid filter (10).
