Abstract
An air cleaner includes a first housing, a second housing, and a filter element. The first housing has an opening. The second housing has an opening that is opposed to the opening of the first housing. The filter element is arranged between the opening of the first housing and the opening of the second housing. At least one of the first housing and the second housing includes a corner portion, a sound reducing member, and an air chamber. The corner portion is constituted by at least two mutually intersecting inner surfaces of the housing. The sound reducing member includes a sound absorbing portion made of an air permeable material. The sound reducing member bridges the at least two inner surfaces and covers the corner portion. The air chamber is defined between the sound reducing member and the corner portion.
