PROBLEM TO BE SOLVED: To enhance installation characteristics of a clean room, simplify work at the time of changing layout, enhance transportation characteristics of an air-cleaning device, and reduce material cost for ceiling grids and installation cost by employing a simple ceiling grid frame and the air-cleaning device. SOLUTION: A packing 3 made of a soft material capable of avoiding air leakage by making a gap as small as possible by self-weight of the air-cleaning device is used between a top face of the ceiling grid frame 11 and a bottom face of the air-cleaning device 2. A hook for transportation is provided on a side face of a main body, and the air-cleaning device can be transported by hooking a tip end of a handle. An air-cleaning system has the longitudinal direction of the ceiling grid frame aligned with the longitudinal direction of each area for the respective areas of the clean room.
