[0002] Most car or indoor air purifiers use a filter + activated carbon method to remove particulate matter and harmful substances in the car. However, after actual use, this type of purifier was found to have the following problems: 1. The effect of removing chemical pollutants such as formaldehyde, benzene and odor is poor; 2. The sterilization effect is poor; 3. After the filter is saturated with adsorption, the formaldehyde removal effect drops sharply; 4. The filter is prone to breeding bacteria, which may cause secondary pollution.

[0003] Therefore, how to solve the above technical problems and develop an air purifier that can efficiently remove chemical pollutants such as formaldehyde, benzene and odor while abandoning the filter structure is a topic that technicians in this field need to focus on.
