Publication number: 20230390688Abstract: The present invention relates to a washable fine dust filter module using nano fibers, the filter module comprising: a filter member (10) having a multi-layered structure that includes a nano fiber layer using nano fibers and is corrugated at regular intervals; and a water-repellent treated filter frame (20) for accommodating the filter member (10). The filter module manufactured using the nano fibers according to the present invention can remove fine dust in the nano fiber layer and an MB filter layer, and thus increase filter efficiency. Also, the filter frame is treated so as to be water repellent, and a hot melt coating layer is applied to only a portion of the thickness of the upper and lower sections of the filter member, such that a user can use the filter module by freely and repeatedly washing the filter module with water (a washable function is imparted).Type: ApplicationFiled: July 9, 2021Publication date: December 7, 2023Inventors: Se Gil SONG, Sung Wook YANG
