The present invention provides a gas adsorbent excellent in the performance of removing aldehydes such as acetaldehyde under dynamic conditions in which air flows, such as an air filter. SOLUTION: An adsorbent in which at least one of an inorganic fine powder and an acid hydrazide compound is supported on a granular inorganic porous body, and a pH of 3.0 to 7 when 5 g of the adsorbent is dispersed in 100 g of water. A gas adsorbent characterized by being in the range of .5. [Selection figure] None |
