Thirteen episodes were produced by Kyoto Animation: twelve regular episodes, and a final recap episode which summarizes Misuzu's story arc. On November 17, 2004, a teaser DVD named "Air prelude" was produced containing interviews with the cast, clean opening and ending sequences, and promotional footage of the anime itself. It was a limited edition DVD, with only 20,000 copies produced. The episodes aired between January 6 and March 31, 2005 on the BS-i Japanese television network. After the conclusion of the anime series, a mini-series which added to the Summer arc of the story called Air in Summer aired on August 28 and September 4, 2005 a week later on BS-i. Air in Summer consisted of two episodes and was produced by the same staff as the anime series.
