Abstract
The present invention relates to an air filtering system capable of enhancing inspection convenience, which is disposed in the ceiling and comprises a housing, a filter, a first sampling tube, and a second sampling tube. On both ends of the housing, an intake and an outtake are disposed opposite to each other. The filter is disposed in the housing, and has an intake surface and an outtake surface opposite to each other. The filter divides the inner space of the housing into a first sampling zone and a second sampling zone. A first end of the first sampling tube is fixed on the housing, and communicates with the first sampling zone. Likewise, a first end of the second sampling tube is fixed on the housing, and communicates with the second sampling zone. Besides, a second end of the first sampling tube and a second end of the second sampling tube are both fixed on the wall. Thereby, the inspection convenience for the inspection staffs can be enhanced.
