AIR-CLEANING FILTER HAVING DUST COLLECTING AND DEODORIZING FUNCTIONS AND PREPARATION METHOD THEREFOR
Publication number: 20240226790Abstract: An air-cleaning filter includes a non-woven fabric for dust collection and a non-woven fabric for deodorization having activated carbon particles combined therewith. By adjusting the particle diameter and content of the activated carbon particles and laminating with a non-woven fabric coated with an absorber for other gases, a dust collecting function and a deodorizing function can be imparted at the same time while also creating a structure with a low differential pressure.Type: ApplicationFiled: January 27, 2022Publication date: July 11, 2024Applicant: COWAY Co., Ltd.Inventors: Hyun Jun YUN, Byong Hyoek LEE, Jong Cheol KIM -
Publication number: 20240189747Abstract: An antibacterial filter, a method for manufacturing the filter, and an air purifier comprising the filter. The antibacterial filter contains a specific range of active copper particles bound to the surface of fibers, and thus can effectively prevent microorganisms, such as bacteria, fungi, and viruses, harmful to the human body, from proliferating on or contaminating the filter surface, and further improve antibacterial performance and sustained antibacterial performance. Additionally, when the antimicrobial filter is applied to an air purifier, it is possible to supply purified air and, at the same time, further improve the durability and lifetime characteristics of the filter.Type: ApplicationFiled: February 17, 2022Publication date: June 13, 2024Applicant: COWAY Co., Ltd.Inventors: Hyun Jun YUN, Hyun Kyu LEE, Hu Min LEE, Jong Cheol KIM, Byong Hyoek LEE, Kyung Hwan LEE

Publication number: 20240033674Abstract: The tube-shaped pleated filter member may comprise: a filter body having a tube shape such that a filter medium is pleated and is wound; and a support unit. The filter body may comprise outer pleated portions corresponding to the outside of the tube shape, and inner pleated portions corresponding to the inside of the tube shape. An inner virtual line connecting corners of the inner pleated portions may have the shape in which a unit wave shape recessed in the outward direction is repeated. Assuming, that the thickness at a part having the maximum distance between the inner virtual line and the outer virtual line is a first thickness (T1), the first thickness (T1) may have a range defined by [equation 1] with regard to the diameter (D) of the outer virtual line. D/15?T1?D/6.Type: ApplicationFiled: September 15, 2020Publication date: February 1, 2024Applicant: COWAY CO., LTD.Inventors: Hyun-Jun YUN, Byong-Hyoek LEE, Jong-Cheol KIM, Jin-Min KIM, Sang-Hyeon KANG
