An air filtration system for purifying an air stream, such as the intake air for an internal combustion engine, including a system plate (10), an unfiltered air zone (13), a filter housing (12) containing a filter element (16), and a filtered air zone (19). The filter element hermetically seals and separates the unfiltered air zone (13) from the filtered air zone. The unfiltered air zone (13) is configured by a first half shell (11), which is connected to the system plate (10) in a fixed, hermetically sealed manner. The filter housing (12) is also connected to the system plate in a fixed and sealed manner. The permanent, air-tight connection of the first half shell to the system plate allows the air filtration system to be manufactured in a simpler, more rapid and more cost effective manner by obviating the need for seals and connecting elements, as well as the need to assemble such parts.
