Air conditioner with selective filtering for air purification

A split air conditioner system including an indoor mounted unit, the indoor unit comprising:

• a cabinet for mounting to a wall of a structure near the ceiling, the cabinet including an air inlet at the top and an air outlet at the bottom;
• an evaporator positioned within the cabinet;
• a fan positioned in the cabinet for admitting untreated air into the cabinet through the air inlet and discharging conditioned air from the outlet of the cabinet;
• and
• a filter positioned on the cabinet at the air inlet for filtering air, wherein the filter is selectively moveable between different positions that provide variably adjustable amounts of filtering of air.

A split air conditioner system including an indoor mounted unit, the indoor unit comprising:

• a cabinet;
• an evaporator positioned within the cabinet;
• a fan positioned in the cabinet;
• an air inlet formed in the cabinet for drawing untreated air into the cabinet to allow the fan to move air in an airflow path from the air inlet through the evaporator and out of the cabinet;
• one of a filter or a stacked filter movably positioned in the cabinet in the air flow path between the air inlet and the outlet at different positions in the air flow path and wherein the different positions provide variably adjustable amounts of filtering of air;
• and
• at least one movable damper positioned in the cabinet for selectively changing the airflow path to selectively bypass the filter.
