One problem to be addressed by the present invention according to an embodiment thereof is to provide an air purifier which while enabling deodorization and humidification is capable of suppressing airflow resistance even if a housing is reduced in size. The present invention is provided with: air intake ports (13a 13c) air discharge ports (14a 14c) an airflow passage which connects the air intake ports (13a 13c) and the air discharge ports (14a 14c) a deodorization unit (23) provided with a deodorization filter (23a) and a humidification unit (24) provided with a humidification filter (24a). The deodorization unit and the humidification unit are arranged inside the airflow passage (10) in that order along the airflow passage (10) in the airflow direction such that a portion of the deodorization unit (23) and a portion of the humidification unit (24) overlap each other.
