The invention discloses an air conditioner. The air conditioner comprises a shell and at least one filter net. An air outlet is formed in the shell. Each filter net is adaptive to moving between the first position state when the filter net is located in the shell and the second position state when the filter net is at least partially located outside the shell. According to the air conditioner, by moving the filter nets from the first position state when the filter nets are located in the shell to the second position state when the filter nets are at least partially located outside the shell, the filter nets can at least partially extend out of the shell, and users can directly clean the filter nets or firstly dismount the filter nets from the shell and then clean the filter nets, so that the using demands of the users are met.
