An air conditioner comprising:

• a housing
• a fan provided in the housing and configured to generate an air flow;
• and
• an electrostatic filter provided in the housing and configured to clean air in the housing,
• wherein the electrostatic filter comprises:
• a plurality of first electrostatic films to which a first voltage is applied;
• a plurality of second electrostatic films provided, respectively, between the plurality of first electrostatic films and to which a second voltage is applied, the second voltage being relatively smaller than the first voltage;
• a case defining a space in which the plurality of first electrostatic films and the plurality of second electrostatic films are received, the case having a first contact space in which end portions of the plurality of first electrostatic films are exposed and a second contact space in which end portions of the plurality of second electrostatic films are exposed;
• and
• a contact bracket provided in the first contact space or the second contact space and electrically connecting the plurality of first electrostatic films or the plurality of second electrostatic films to each other, and
• wherein the contact bracket contacts the end portions of the plurality of first electrostatic films or the end portions of the plurality of second electrostatic films, and the contact bracket is slidingly coupled to the case.
