Abstract: A sealed air purifier is disclosed. A housing is formed by connecting a first shell and a second shell. The first shell and the second shell communicate via separable connecting base and connector. A retractable bag encloses the connecting base and the connector. A sealing structure is provided between both ends of the bag. The first shell has an air inlet connecting the inside and the outside and a gate to control the airflow. A compression assembly is disposed in the first shell. The second shell has an air outlet connecting the inside and the outside and a blocking element to control the air outlet. The second shell has a sterilizing device and a super ULPA filter. When the gate closes the air inlet, the compression assembly, sterilizing device, and the air outlet close correspondingly, so that the inside of the housing is isolated. Thus, the viruses remaining therein do not spread with air.
