What is claimed is: 1. An apparatus for freshening air, the apparatus comprising: a base unit having a recess configured to engage at least one cartridge; a power supply operably connected to the base unit; an active portion of a nebulizer, wherein the active portion includes a piezoelectric element connected to be driven by a driving and switching circuit connected to be powered by the power supply, wherein the active portion of the nebulizer is incorporated with the base unit; a detachable autonomous liquid droplet dispensing cartridge detachably engagable with the recess of the base unit, wherein the cartridge comprises (a) a first airless bag for storing a first nebulizable liquid, (b) a second airless bag for storing a second nebulizable liquid, (c) a passive portion of the nebulizer, wherein the passive portion includes an interface, a nozzle membrane that incorporates a nozzle array, and a joining member, wherein the joining member engages the piezoelectric element when the cartridge is engaged in the recess of the base unit; and (d) a casing enclosing the first bag and the second bag, and housing the passive portion; wherein when the dispensing cartridge is engaged with the recess of the base unit, the passive portion is connected to the active portion of the nebulizer. 2. An apparatus for refreshing air as recited in claim 1, wherein when the dispensing cartridge is engaged with the recess so that the passive portion is connected to the active portion of the nebulizer, the nebulizer is connected to each bag by a respective inlet of the interface, so that, when the nebulizer operates, and first and second nebulizable liquids are contained in the first and second bags, respectively, the first nebulizable liquid flows from the first bag and the second nebulizable liquid flows from the second bag so that the first nebulizable liquid and the second nebulizable liquid are mixed by nebulization. 3. An apparatus for refreshing air as recited in claim 2, wherein the interface of the passive portion includes a separation that prevents mixing of the first nebulizable liquid and the second nebulizable liquid until each liquid is in the form of a nebulized mist. 4. An apparatus for refreshing air as recited in claim 2, wherein the passive portion includes an internal space and the first nebulizable liquid and the second nebulizable liquid are mixed in the internal space before being nebulized into a combined mist by the operating nebulizer. 5. An apparatus for refreshing air as recited in claim 2, wherein the interface includes a first inlet that provides a path of egress for the first liquid and a second inlet that provides a path of egress for the second liquid, so that, when the nebulizer operates, and first and second nebulizable liquids are contained in the first and second bags, respectively, the first nebulizable liquid and the second nebulizable liquid flow from the first bag and the second bag, respectively, through the interface and into the nebulizer. 6. An apparatus for refreshing air as recited in claim 1, wherein the nozzle membrane has at least one nozzle sized to disperse droplets that are about 1-7 microns in diameter. 7. An apparatus for refreshing air as recited in claim 1, wherein the nozzle membrane has at least one nozzle sized to disperse droplets that are about 5-30 microns in diameter. 8. An apparatus for refreshing air as recited in claim 2, further comprising a switch disposed in the driving and switching circuit and electrically connected to the power supply, wherein the switch activates the nebulizer and the flow of the first nebulizable liquid and the second nebulizable liquid from the first airless bag and the second airless bag, respectively, through the interface and into the nebulizer. 9. An apparatus for refreshing air as recited in claim 8, wherein the switch is operable by a remote unit. 10. An apparatus for refreshing air as recited in claim 1, wherein the first bag contains a first nebulizable liquid that is different from a second nebulizable liquid contained in the second bag. 11. An apparatus for refreshing air as recited in claim 10, wherein the first nebulizable liquid is a primary fragrance and the second nebulizable liquid is a disinfectant. 12. An apparatus for refreshing air as recited in claim 3, wherein the first bag contains a first nebulizable liquid that is different from a second nebulizable liquid contained in the second bag, and the first nebulizable liquid and the second nebulizable liquid are not chemically stable in liquid mixture.
