Claim:
1. A method of manufacturing an atomising body for an atomising device, the method comprising the steps of providing a support element having a first layer on a first surface of the support element and a second layer on a second surface of the support element, the first layer comprising a first perforated membrane and the second layer comprising a process orifice and a second perforated membrane arranged adjacent the process orifice; and etching a cavity through the support element, the cavity forming a fluid connection from the process orifice to the first perforated membrane and from the first perforated membrane to the second perforated membrane, by providing an etching substance to the process orifice; juxtaposingly disposing a cover at the second perforated membrane and over the process orifice; and sealing the process orifice by the cover to form the atomising body, wherein the step of sealing the process orifice by the cover comprises: covering the process orifice by the cover while maintaining a small gap between the cover and the process orifice, the gap configured to be small enough to filter particles so as to prevent particles from entering the cavity via the process orifice.
