An air filtration system includes a main body having a flow path; a first filter portion provided on the flow path and having a first body portion; a plurality of protrusions distributed and disposed on the first body portion; and a plurality of first through holes passing through the first body portion and interposed between the adjacent protrusions; wherein when an external fluid flows in the flow path, the external fluid passes through the protrusions first and then passes through each of the first through holes, so that the flowing external fluid is hindered by the protrusions, and thus a flow velocity at a position adjacent to the protrusions is lower than a flow velocity flowing through the first through holes, thereby vortices are respectively generated between orifices of the first through holes and the adjacent protrusions.
