A sleeve extends around the tube to facilitate the exhaust pipe to extend between the tube and the sleeve. A handle is pivotally coupled to the tube for inserting the tube into the exhaust pipe. A filtering cartridge is insertable into the tube. Each filtering element of a plurality of filtering elements of the filtering cartridge is made of a unique pollutant filtering material with respect to each other.
