Abstract: A composite filter includes a filter unit including a filter member having filtering parts, at least one filter module arranged in parallel with at least one of the filtering parts, and a bracket supporting the filtering parts disposed adjacent to each other and the filter module so that the filtering parts disposed adjacent to each other are rotatable. The bracket includes a folded portion that is selectively folded according to the relative rotation of the filtering parts, and attachment portions connected to the folded portion with the folded portion interposed therebetween, and attached to the side surfaces of the filtering parts disposed adjacent to each other. The folded portion and the attachment portions are provided integrally and are formed of a flexible material, and the attachment portion extend to the side surface of the filter module adjacent thereto to seal a gap between the filtering part and the filter module.

Abstract: An air purifier is disclosed. The air purifier according to an aspect of the present invention may include a housing that forms an external shape and has a housing space therein that communicates with the outside; and an air purification unit that is coupled to the housing, comprises a fan member that provides a conveying force to allow external air to be introduced into the housing space of the housing, and a filter member that filters external air introduced into the housing space, and purifies the external air introduced into the housing space and then discharges it to the outside, wherein the housing includes a clean inlet part partially surrounding the housing space, formed through one or more surfaces of the housing, and communicating the housing space and the outside; and a dust inlet part partially surrounding the housing space, formed through one or more surfaces of the housing, and communicating the housing space and the outside at a position different from the clean inlet part, wherein the clean inlet part is configured to be open or closed, and when the clean inlet part is closed, the speed of external air introduced into the dust inlet part is increased by the fan member.
