Automated air freshener dispensers and cartridges therefor are provided herein. Air freshener dispensers include a housing having a cavity for receiving a cartridge containing an air freshening substance for release, a fan that induces an airflow through the housing and directs the airflow to an area outside of the air freshener dispenser, such that released air freshening substance is entrained in the airflow, a motor for driving the fan, at least one sensor, and a controller that receives a signal from the at least one sensor and directs operation of the fan in response thereto.

1. An air freshener system, comprising: a cartridge comprising a body that comprises a matrix material impregnated with an air freshening substance for release selected from an odor-combatting composition, a fragrance, and a combination thereof, the body having a volume of from about 0.1 in3 (1,600
1. An air freshener system, comprising: a cartridge comprising a body that comprises a matrix material impregnated with an air freshening substance for release selected from an odor-combatting composition, a fragrance, and a combination thereof, the body having a volume of from about 0.1 in3 (1,600 mm3) to about 2.5 in3 (41,000 mm3) and a surface area of from about 2.0 in2 (1,300 mm2) to about 40 in2 (26,000 mm2);a housing that comprises a cavity containing the cartridge;a fan within the housing that induces an airflow through the housing and directs the airflow to an area outside of the housing, such that released air freshening substance is entrained in the airflow directed from the housing;a motor within the housing for driving the fan;at least one sensor; anda controller within the housing that receives a signal from the at least one sensor and directs operation of the fan in response thereto. 2. The air freshener system of claim 1, wherein the body comprises a plurality of ribs extending from a substrate and forming airflow channels therebetween. 3. The air freshener system of claim 2, wherein: the housing further comprises an air inlet,the cavity and cartridge are sized and shaped such that the cartridge is oriented in the cavity such that the airflow channels of the cartridge are aligned with an airflow path between the air inlet and the fan. 4. The air freshener system of claim 2, wherein: the housing further comprises an air inlet,the housing further comprises at least one projection within the cavity,the cartridge comprises a recess configured for mating engagement with the projection of the housing, andthe projection is configured to orient the cartridge in the cavity such that the airflow channels of the cartridge are aligned with an airflow path between the air inlet and the fan. 5. The air freshener system of claim 4, wherein the at least one projection is configured to allow airflow thereby in the recess of the cartridge. 6. The air freshener system of claim 1, wherein the cavity has a headspace volume of from about 1 in3 (20,000 mm3) to about 4 in3 (70,000 mm3). 7. The air freshener system of claim 1, wherein the housing has a headspace volume of from about 15 in3 (250,000 mm3) to about 45 in3 (740,000 mm3). 8. The air freshener system of claim 1, wherein the airflow comprising the entrained released air freshening substance is directed from the housing at a volume of from about 0.1 ft3/min (0.003 m3/min) to about 10 ft3/min (0.3 m3/min). 9. The air freshener system of claim 1, wherein the cartridge has a surface area that is sufficient to infuse a headspace of the cavity with air freshening substance released from the cartridge every 30 seconds, in the absence of the fan being driven. 10. An automated air freshener dispenser, comprising: a housing that comprises a cavity for receiving a cartridge comprising an air freshening substance for release;a fan within the housing that induces an airflow through the housing and directs the airflow to an area outside of the air freshener dispenser, such that released air freshening substance is entrained in the airflow directed from the air freshener dispenser;a motor within the housing for driving the fan;at least one sensor; anda controller within the housing that receives a signal from the at least one sensor and directs operation of the fan in response thereto,wherein the housing of the air freshener dispenser is mountable to a bath tissue dispenser housing,wherein the housing further comprises an air inlet and an airflow outlet through which the airflow comprising the entrained released air freshening substance is directed from the air freshener dispenser, andwherein an airflow path from the air inlet to the airflow outlet is tortuous. 11. The air freshener dispenser of claim 10, wherein the housing of the air freshener dispenser is configured to be snap fit to the bath tissue dispenser housing. 12. The air freshener dispenser of claim 10, wherein the at least one sensor is selected from a group consisting of motion sensors, light sensors, malodor sensors, switches, and combinations thereof. 13. The air freshener dispenser of claim 10, wherein the housing further comprises an airflow outlet through which the airflow comprising the entrained released air freshening substance is directed from the air freshener dispenser. 14. The air freshener dispenser of claim 13, wherein the fan is positioned within the housing between the airflow outlet and the cavity. 15. The air freshener dispenser of claim 10, wherein the airflow comprising the entrained released air freshening substance is directed from the air freshener dispenser at a volume of from about 0.1 ft3/min (0.003 m3/min) to about 10 ft3/min (0.3 m3/min). 16. The air freshener dispenser of claim 10, wherein the controller directs the motor to drive the fan for a predetermined duration in response to receipt of a signal from the at least one sensor. 17. The air freshener dispenser of claim 10, wherein the controller further determines whether the fan has been driven within a predetermined period preceding receipt of a signal from the at least one sensor and prevents the motor from driving the fan in response to receipt of the signal if the fan has been driven within the predetermined period preceding receipt of the signal. 18. An automated air freshener dispenser, comprising: a housing that comprises a cavity for receiving a cartridge comprising an air freshening substance for release;a fan within the housing that induces an airflow through the housing and directs the airflow to an area outside of the air freshener dispenser, such that released air freshening substance is entrained in the airflow directed from the air freshener dispenser;a motor within the housing for driving the fan;at least one sensor; anda controller within the housing that receives a signal from the at least one sensor and directs operation of the fan in response thereto,wherein the housing comprises at least one projection within the cavity, the projection being configured for mating engagement with a recess of the cartridge and comprising a plurality of ribs or posts. 19. An automated air freshener dispenser, comprising: a housing that comprises a cavity for receiving a cartridge comprising an air freshening substance for release;a fan within the housing that induces an airflow through the housing and directs the airflow to an area outside of the air freshener dispenser, such that released air freshening substance is entrained in the airflow directed from the air freshener dispenser;a motor within the housing for driving the fan;at least one sensor; anda controller within the housing that receives a signal from the at least one sensor and directs operation of the fan in response thereto,wherein the housing comprises a door that provides access to the cavity, andwherein the housing comprises at least one projection within the cavity and located on the door, the projection being configured for mating engagement with a recess of the cartridge.
