Abstract
An air cleaner is provided that may include a main body having at least one cylindrical filter and at least one filter frame that forms a mounting space for the at least one filter, and a cylindrical case coupled to an outside of the main body, the cylindrical case having at least one suction inlet through which air is suctioned toward the at least one filter, so that air may be suctioned in 360-degree directions. If the cylindrical case is opened, the at least one filter may be extracted to the outside in a radial direction from the mounting space, thereby facilitating attachment/detachment of the at least one filter.
