An air freshener has a casing, a solid aromatic, a cover, an air passage and a fastening device. The casing has a cavity and an air inlet. The aromatic solid is mounted securely in the cavity. The cover is mounted on the casing and has an air vent. The air passage is between the cover and the casing and communicates with the cavity, the air vent and the air inlet. Air flows into the air freshener through the air inlet, passes through the air passage and leaves through the air outlet. When the air passes through the air passage, the fragrance of the aromatic solid is mixed with and leaves with the air discharged through the air vent.
