a) placing the dry powder in a reservoir;
b) placing a filter in a filter holder, said filter comprising a porous substrate having an inlet surface and an outlet surface, said inlet surface and said outlet surface being separated by a porous structure; a step of placing,
c) establishing a primary gas flow through said porous structure of said filter by applying a pressure drop to said outlet face of said filter;
d) transferring said dry powder from said reservoir to a spray device located upstream of said inlet face of said filter;
e) directing the dry powder, using the atomizing device, toward the inlet face of the filter so that it is entrained in the primary gas stream, passes through the inlet face of the filter and contacts the porous structure; and spraying said dry powder with a.

i) a reservoir for containing dry powder;
ii) a filter holder for holding a filter, said filter being of the type comprising a porous substrate having an inlet surface and an outlet surface, said inlet surface and said outlet surface being separated by a porous structure; a filter holder;
iii) a vacuum generator for establishing a primary gas flow through said porous structure of said filter during use by applying a pressure drop to said exit face of said filter;
iv) a transport device for transporting the dry powder from the reservoir towards the filter;
iv) a spray device for receiving the dry powder from the transport device and spraying the dry powder towards the inlet face of the filter;
v) a controller configured to control operation of at least said vacuum generator and said atomizing device.
