PURPOSE:To provide an air filter with a longer life which has a sufficient cleaning effect even in a limited space while preventing a drop in pressure loss. CONSTITUTION:This air filter 17 is arranged between a prefilter 13 provided at an air suction port of an air conditioner 3 and a heat exchanger 5. The air filter 17 is so shaped that the shape of the unevenness of a pleat 14 matches the contour of a space between the prefilter 13 and the heat exchanger 5 as a whole. |
