A method of generating a dry fog comprises nebulising a provided preparation and delivering it to a desired density, with particles of a predetermined size, within a predetermined time. The nebulising device preferably possesses a piezoelectric transducer 10 which nebulises the preparation / solution ideally provided in a container 6. A fan 13 may assist in delivering or dispersing the dry mist / fog, the speed of the fan being variable to control particle size and/or delivery rate. The particle size may be between 1 â 8 micrometres, preferably 1 - 2 microns. The atomised solution may be delivered by a duct 3, the length and internal shape of the duct being adjustable to control the particle size. By having atomised particles of a very small diameter, dry mist is formed. An independent claim relates to decontaminating a space by nebulising a decontaminant solution, the duct adapted to control the size of the nebulised particles. |
