1. An air purification filter comprising:
a filtering layer configured as a dielectric;
a pair of electrode layers provided at opposite sides of the filtering layer, respectively, and configured to receive power so as to generate an electric field in the filtering layer; and
a connection module including:
a coupled portion that is coupled to at least one of the pair of electrode layers and is insulated from an outside of the connection module, and
a module terminal that electrically connects the coupled portion of the connection module with a power supply,
wherein the connection module includes a module housing that comprises a first housing having a connection space, and a second housing configured to cover the connection space when coupled to the first housing and at least one of the pair of electrode layers is inserted into the connection space and is electrically connected to the module terminal.
