This invention relates to a filter for smoking devices wherein the heat caused by combustion of the tobacco products causes the release of encapsulated fluid and the consequent moistening of the filtering material disposed within the device. The fluid is retained in capsules the walls of which are constituted of waxlike material which is melted when the heat of the smoke is concentrated in ''''jet'''' form thereon by a truncated conical baffle the smaller end of which is in proximity to the capsules and the larger end is close to the tobacco charge. |
