Along with the continuous improvement of the living quality level of people, the requirements of people on the air quality are also continuously improved, and therefore, the air treatment equipment has higher and higher standards for air purification. In the prior art, bag type filter screens used by air treatment equipment are mostly only provided with air inlets and air outlets, which can result in large purification resistance. Meanwhile, as shown in fig. 1, most of the bag filters used in the prior art air treatment apparatuses are planar, which results in insufficient filtering area. Therefore, the bag filter screen in the prior art has poor filtering effect and cannot meet the high-standard purification requirement.
