1. An air conditioner comprising:
a main body including a heat exchanger and a first fan to move indoor air to pass through the heat exchanger; and
a ventilation apparatus mountable on the main body to ventilate a room,
wherein the ventilation apparatus comprises:
a case configured to accommodate a second fan;
a ventilation pipe including an inlet tube having a first end mountable to an outdoor air inlet formed in a building wall and a second end opposite to the first end so as to be positioned away from the building wall while the first end is mounted to the outdoor air inlet, and an extension tube to connect to the inlet tube at the second end of the inlet tube to thereby form a flow path between the case and the inlet tube, the extension tube being detachable from the inlet tube; and
a ventilation filter installable in the ventilation pipe through a connection portion between the inlet tube and the extension tube to filter out substances in air introduced through the outdoor air inlet, the ventilation filter including a support part having an outer diameter larger than inner diameters of the inlet tube and the extension tube.
