1. A paint mist removing apparatus comprising:
a duct through which air containing paint mist passes;
an element fit part provided at the duct and housing a filter element, the filter element including a filter part configured to remove the paint mist and a filter case housing the filter part, the filter case having a case exit from which all air taken in from a case entrance of the filter case is caused to exit through the filter part;
a frame projection projecting from an inner surface of the duct and abutting on an entire circumference of an opening edge of the case exit of the filter case;
a duct side-surface opening and a door, the duct side-surface opening being open at a side surface of the duct and configured to be closed by the door, the duct side-surface opening being open when the filter element is set in and out from the element fit part in a direction through the duct side-surface opening; and
an overhang extending from the inner surface of the duct at a position upstream of the filter element with respect to a direction of air flow through the duct so that the overhang covers a gap between the filter element and the duct, the overhang having a frame including side walls that extend from the inner surface of the duct in an inward direction that is inclined in a direction towards the filter element so that a width dimension of the overhang narrows in the direction towards the filter element.
