An exhaust filter attachment adapted to be attached to the exhaust pipe and carried rigidly thereon of any motored vehicle. This attachment is designed to filter all products of combustion leaving the vehicle, and to chemically treat the poisonous and health destructive gases; such as, the carbon monoxide and sulphur. The attachment comprises generally a sleeve housing with a conical mesh member extending from the forward end of the sleeve housing, and having thereon an attaching sleeve that will be secured to the end of the exhaust pipe by a clamp ring. Air is drawn inwardly or injected by the exhaust action of the gases being expelled from the exhaust pipe, and the mixture will be forced through a series of removable filter members extending transversly of the flow of the gases within the tube. Each of the filter elements comprises rings with filter material disposed between mesh disc end closures. When the filtering elements have been used they can be replaced or cleaned. The filtering material in these elements is chemically treated to consume the poisonous gases, reacting therewith to convert them into non-harmful gases. A charcoal device attachment is provided to be mounted on the sleeve, at the end thereof, and has an incline disc supporting charcoal particles in various degrees of longitudinal extent from the bottom to the top of the filter device so as not to seriously impede the flow of gases at the trailing end of the filtering attachment. Adequate drain mesh screens are provided in the spaces between the filtering elements and the charcoal material to get rid of water accumulation, and to provide means through which a particle accumulation can be observed to determine cleaning.
