A holder for compressing a filter of a cigarette includes a cylindrical gripping member having an end provided with a plurality of longitudinal pawls, and a tubular mouthpiece formed with an axial passage having an end open to outside and an axial conical recess having a small end in communication with another end of the axial passage, the axial conical recess being formed with a conical surface, whereby when the gripping member is inserted into the mouthpiece, the longitudinal pawls will be forced to move inwardly to compress the filter of a cigarette to one-fifth of its original volume thereby decreasing the amount of nicotine and tars from passing therethrough.
