摘要： A liquid discharge apparatus including a head configured to discharge a liquid, a chamber configured to contain the head, a circulation system configured to circulate a gas inside the chamber, an exhaust system configured to operate to exhaust the gas to an outside of the chamber, a filter provided in the circulation system and configured to remove a removal target contained in the gas, a detection unit configured to indirectly detect the removal target by detecting a detection target that is contained in the gas and different from the removal target, and a controller configured to operate the exhaust system when a concentration of the detection target detected by the detection unit is not lower than a threshold.
