  As a result, when smoke is smoked in a room, the smoke rising from the cigarettes placed in the ashtray and the smoke exhaled from the person's mouth can be efficiently sucked in at the same time. It can be shortened. Therefore, the running cost of the air cleaner can be reduced, and the room can be used comfortably without worrying about the smell of tobacco after a short time.

   When there is no restriction on the installation area of the air cleaner, as shown in FIGS. 6 and 9, the leg 10 is rotated outward to tilt the leg 10 and tilt the main body case 4. As a result, since the lower front intake port 5a faces farther, the air at the lower front of the main body case 4 can be efficiently sucked in, and the upper lower intake port 5a is not drawn into the main body case 4 from the front intake port 5b. The amount of smoke that diffuses can be further reduced.

  In addition, since the front air inlet 5b faces upward, smoke diffused above the room can be sucked more efficiently. Therefore, the operation time of the air purifier can be further shortened, the running cost can be further reduced, and the room can be used comfortably without worrying about the smell of cigarettes in a shorter time. . By tilting the main body case 4 to the rear, the center of gravity moves rearward, so that the main body case 4 tends to fall backward.
