A tobacco filter device includes a plurality of filter units superimposedly rechargeably filled in a sleeve member, having a bowl member connected to an outer end (smoking end) of the sleeve member and a mouthpiece connected to an inner end (mouth end) of the sleeve member, whereby upon smoking of tobacco or a cigarette as loaded or inserted in the bowl portion, the filter unit or units positioned on an outer portion of the sleeve member adjacent to the smoking end, after being saturated with smoking waste including tar and nicotine, may be pushed outwardly and discarded from the outer end of the sleeve member as thrusted and urged by a fresh (new) filter unit (or units) as recharged into the inner (mouth) end of the sleeve member, thereby still keeping use of those filter units not yet saturated and loaded in the rear portion of the sleeve member, without wasting the useful filter units.
