Abstract

The invention comprises a method of separating out unwanted ingredients of tobacco smoke and a filter using the method. The method consists in passing the smoke gases through an intimate mixture of fine solid particles, one ingredient of which forms one electrode and the other ingredient of which forms the other electrode of a large number of galvanic micro cells which become such by the aerosol particles precipitated on such electrodes when the smoke starts. Fine grains for a filter holder and fine filaments for a filter are given coatings of copper or silver and zinc by vapour coating and spraying to form electrodes of galvanic micro cells each cell having a voltage of 1v.
