Abstract: A pipe assembly is provided to accommodate the specific filter preferences of the pipe smoker. The pipe assembly includes a bowl, a stem and a mouthpiece. A cylindrical mounting aperture extends into the end of the stem remote from the bowl, and a connecting passage joins the mounting aperture to the tobacco receiving cavity in the bowl. The mouthpiece has a proximal end with a passage therein and a distal end that can be slidably received in the mounting aperture of the stem. The mouthpiece further includes a filter receptacle that communicates with the passage extending into the proximal end of the mouthpiece. The filter receptacle is dimensioned to accommodate wide prior art filters. The pipe assembly further includes a tubular filter adapter with an outside diameter for slidable engagement in the filter receptacle and an inside diameter dimensioned to receive narrower pipe filters.
