Filter element of novel air filter

The utility model discloses a filter element of a novel air filter, which consists of a filter paper, an inner net and an outer net wrapped on the inner and outer surfaces of the filter paper, and an upper cover and a lower cover arranged at the upper and lower ends of the filter paper. The key point of the filter element is that one or more threads are fixedly adhered between the filter paper and the inner and outer nets. The threads are high-temperature cotton ones, and are adhered on the filter paper by hot melt glue. Therefore, the position of the filter paper is axially fixed on one hand, and the looseness of the filter paper can also be prevented in the radial motion process on the other hand. The entire designed structure is simple and firm, and the filtering performance of the filter is not affected so as not to need frequent replacement of the filter paper, so that the service life of the filter is prolonged.
