Abstract
An air freshener that includes a base and a reservoir is disclosed. The base includes a fan housed therein and one or more base openings extending through a sidewall of the base. The one or more base openings comprise an inlet opening and an outlet opening. The base also includes a coupling receiver positioned on an upper surface of the base. The reservoir includes a reservoir chamber configured to hold a scented liquid therein and an outlet. A coupling is typically coupled to the reservoir adjacent to the outlet and configured to removably couple to the coupling receiver. A filter is coupled to the coupling and in fluid communication with the reservoir chamber. The filter is positioned above the fan when the coupling is removably coupled to the coupling and allows the scented liquid to evaporate therefrom for dispersal through the base openings when the fan is activated.
