Abstract
A device suitable for use in filters for tobacco and other smoke, consisting of an electret with at least two substantially parallel surfaces, one of whose surfaces has a layer of conductive material adhered thereto, a second electret with minus two substantially parallel surfaces, one of whose surfaces has a layer of conductive material adhered thereto, and an intermediate layer of adherent material which links said two electrets together by the respective layers of conductive material in such a way that electrical contact is maintained between said two conductive materials.
