Claim 15:
16. An air conditioner comprising:
a housing comprising an outlet;
a power supply disposed inside of the housing;
a panel assembly attachable to or detachable from a lower side of the housing, the panel assembly configured to be moved in an up and down direction with respect to the housing;
a lifter disposed inside of the housing and configured to lift or lower the panel assembly in a vertical direction while maintaining a horizontal state of the panel assembly; and
a guide configured to guide at least a part of the panel to move along the guide upon being in contact with the guide during the lifting of the panel,
wherein the panel assembly comprises:
a panel comprising an inlet to introduce air therethrough and configured to cover the lower side of the housing;
a first filter installable to the panel and configured to filter the introduced air; and
a second filter installable to the panel and configured to further filter the introduced air using an electrostatic force, the second filter comprising a contact portion configured to be in contact with the power supply, and

wherein:
in response to attaching the panel to the lower side of the housing, the contact portion contacts with the power supply so that the power supply supplies power to the second filter to generate the electrostatic force to filter the introduced air; and
in response to detaching the panel from the lower side of the housing, the contact portion is not in contact with the power supply so that no power is supplied to the second filter; and
in response to the lowering of the panel to a maintenance position by the lifter, one or more of the first filter and the second filter are accessible for maintenance.
