[0002] Air purifier, also known as "air cleaner", air refresher, or purifier, refers to a product that can absorb, decompose or transform various air pollutants and effectively improve the cleanliness of the air.

[0003] In the prior art, outside air is generally sucked into the air purifier through a blower. The air first passes through an outer steel wire mesh to filter larger particles, and then the air is filtered twice through a fiber mesh. Thereafter, the odor is filtered through an activated carbon plate, and then sterilized through an ultraviolet lamp. The air is then discharged to the outside through a blower to achieve the purpose of purifying the air. After long-term use, the filter component will produce odor and the filtration efficiency will decrease, and it needs to be cleaned regularly. For this reason, the utility model proposes a high-efficiency air purification filter component. Utility Model Content
