A window type air conditioner includes an indoor heat exchanger, an outdoor heat exchanger and a motor disposed in the shell. Rotating shafts at two ends of the motor are provided with an indoor fan and an outdoor fan. A thermal insulation partition is disposed on a bottom plate of the shell and divides the shell into an indoor side and an outdoor side. The thermal insulation partition includes a front clapboard fixed on the bottom plate of the shell and a thermal insulation volute disposed on the front clapboard. The indoor heat exchanger and the indoor fan are located in the thermal insulation volute. An integrated bracket is provided with a first mounting part for mounting and fixing the outdoor heat exchanger, a second mounting part for mounting and fixing the motor, and third mounting parts for connecting and fixing the front clapboard.

A symmetric pair of mounting brackets for mounting one of a plurality of air filters to a mounting plate of an air conditioner unit are provided. The mounting brackets each define a plurality of mounting surfaces with equidistantly space mounting holes. The mounting surfaces are spaced apart from a plurality of retention surfaces, with the distance between each respective mounting surface and retention surface varying to accommodate a different filter size such that the air conditioner may operate using different filter sizes by simply changing the installation orientation of the mounting brackets.
