An air treatment system having an improved control system. The control system may include a dynamic dead front display that varies the display based on mode of operation. The display may include capacitive touch sensors and include an array of capacitive film segments or traces integrated into the display. The control system may include a self-contained electronics module that can be tested and calibrated before installation in the ATS. A dust sensor assembly may be integrated into the electronics module. The front cover may be attached with a mechanical attachment at the top and a magnetic attachment on the bottom. The ATS may include a filter retainer assembly with a rotating clip configured to perform in a cam-like manner to firmly clamp the particulate filter and carbon filter in place.

Provided is an inverter apparatus provided with a dust collecting unit. The inverter apparatus provided with the dust collecting unit according to an exemplary embodiment of the present disclosure comprises: a housing having an air inlet port formed on one surface and an air discharge port formed on the other surface; an electrical element for inverter, which is arranged in the housing; a first suction member arranged in the housing; and the dust collecting unit arranged on one side of the air inlet port.
