1. An apparatus for dispersing a volatile composition into the atmosphere, which apparatus comprises a housing of an electrically insulating material which is in communication with the atmosphere outside the housing, the housing containing:

  • a source of a volatile composition; and

    means for generating an ion wind comprising a first electrode and a second electrode spaced therefrom to define a region therebetween such that, when a dc electrical field is created in said region, the ion wind facilitates the dispersal of the source of the volatile composition into the atmosphere and causes molecules of the volatile composition to become charged, the source of the volatile composition being disposed in the housing downstream of the first and second electrodes.
