The dispensing unit releases a measured amount of the chemical fragrance when the dispensing unit is turned on. In this way the dispensing unit can enhance odors associated with an area proximate the dispensing unit. A pair of switches is each of the switches is coupled the dispensing unit and each of the switches is turned on when a user sits on the seat. The dispensing unit is turned on when the switches are turned on. In this way the dispensing unit reduces odors associated with the user employing the toilet. ## Claims ### Claim 1 An air freshener dispenser assembly being mountable to a toilet and releasing a
