A polyp filter is non-integral to a corresponding suction-line dedicated polyp track. By one approach this polyp filter has a threaded portion that threadably engages at least one of a suction-line dedicated polyp trap housing and lid. That threaded portion can comprise, for example, a threaded hole that is formed axially through the polyp filter. By one approach that threaded portion threadably engages a threaded tube as comprises a part of the lid.
