In the video, a man is seen kneeling down in front of a large air conditioning unit. He is holding a white filter in his hands and appears to be examining it closely. The man is wearing a white shirt and black pants. The air conditioning unit is gray and appears to be quite large. The background of the video is a plain white wall. The man seems to be speaking, although it is not clear what he is saying. The filter he is holding has a grid-like pattern and appears to be made of plastic. The man's actions suggest that he is either cleaning or repairing the air conditioning unit.
