ABSTRACT:
A filtering and absorbing device for a vehicle's discharge pipe including a housing shell which is connectable to a vehicle's discharge pipe; the shell having a cross-sectional dimension larger than that of the discharge pipe's, cross openings properly spaced from each other on both the bottom and top walls of the housing shell's main body to allow ventilated boxes which contain activated carbon in grain form to be inserted in the housing shell to create a meandering passage so that waste fumes from the vehicle passing the ventilated boxes move along the meandering passage to be treated by activated carbon to produce cleaner air.
