An image projection apparatus that projects light modulated by an optical modulation element onto a projection surface to display an image, the image projection apparatus comprising:

• a cooling fan provided inside a chassis of the image projection apparatus and configured to take in cooling air from a cooling inlet port formed in the chassis;
• an air filter that covers the cooling inlet port;
• an exhaust port formed in the chassis and configured to exhaust the cooling air from an inside to an outside of the chassis;
• and
• a cleaning fan provided inside the chassis and configured to take in cleaning air from a cleaning inlet port formed in the chassis separately from the exhaust port,
• wherein the image projection apparatus exhausts the cleaning air discharged from the cleaning fan, from the inside to the outside of the chassis via the cooling inlet port and the air filter.
