Abstract: 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.
