1. A filter module comprising:
a filter;
a first electrode facing a first surface of the filter;
a second electrode facing a second surface, opposite to the first surface, of the filter; and
a first spacer configured to maintain a space between the first surface and the first electrode,
wherein the filter module is configured to be arranged in a flow path of air so that the air flows through the filter from the second surface to the first surface with the second electrode at an upstream side of the filter along the flow path and the first electrode at a downstream side of the filter along the flow path, and so that the space maintained by the first spacer prevents electrical conduction between the first electrode and the second electrode due to foreign substances collected in the filter upstream of the first surface.
