An article storage apparatus includes a sensor device sensing gases included in air in a chamber where an article is stored; a concentrator concentrating the gases contained in the air; a filtering device filtering the gases contained in the air; and at least one processor. The at least one processor controls the concentrator to concentrate the gases contained in the air, and identifies a condition of the article based on a concentration level of a target gas related to the article measured by the sensor device when the target gas is extracted as gases desorbed from the concentrator pass the filtering device.
