An air freshening device (100) includes a liquid supply operable to supply liquid fragrance material (10), a wick (20) in contact with the liquid supply, a conductive mesh material (30) operable to retain the liquid material in interstices thereof, and a power supply (60) operable to apply voltage across the mesh material so as to heat the mesh material and the liquid fragrance material contained in interstices (35) of the mesh material to a temperature sufficient to vaporize the liquid. The air freshening device is operable to prevent deposition of the vaporized liquid material. A method for generation of vaporized material and a method for repeated pulsed generation of vaporized material is also disclosed.
