A pollutant filtering assembly for filtering pollutants from vehicle exhaust includes a tube that has a diameter which is sufficient to facilitate the tube to be inserted into an exhaust pipe of a vehicle. 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. Moreover, each of the filtering elements can filter pollutants from exhaust of the vehicle.
