[Problem] To provide an air purifier in which the structure for attaching and detaching a dust collection unit is simplified. [Solution] When a first electric dust collector (22a) and a second electric dust collector (22b) are removed, a front panel (13) and a prefilter (21) are first removed from an air purifier (1), and each of a top stopper (16j), a middle stopper (16k), and a bottom stopper (16m) are then turned 180 degrees (so that the long sides are substantially parallel to the installation surface of the air purifier (1)). The first electric dust collector (22a) is removed from a first accommodating part (16a) by using fingers to hook and pull forward on the left and right side surface parts of the first electric dust collector (22a) exposed in left and right first finger insertion parts (16c), and the second electric dust collector (22b) is removed from a second accommodating part (16b) by using fingers to hook and pull forward on the left and right side surface parts of the second electric dust collector (22b) exposed in left and right second finger insertion parts (16d).
