A heat exchange ventilation apparatus includes a box-shaped body casing in which an exhaust air passage that exhausts indoor air to an outside of a room and a supply air passage that supplies outdoor air to an inside of a room are formed, a heat exchanger that is arranged at an intersection portion at which the exhaust air passage and the supply air passage intersect and performs heat exchange between an exhaust air flow flowing in the exhaust air passage and a supply air flow flowing in the supply air passage, and a filter holding unit in which a holding frame that holds a filter on an inflow side of the supply air flow of the heat exchanger and a pan that receives a falling object from the filter are integrated and is attachable and detachable to and from the body casing together with the filter, and improves a maintenance performance and a service performance. |
