We claim the ornamental design for a cylindrical filter element, as shown and described.

FIG. 1 is a front elevational view of a cylindrical filter element showing our new design;

FIG. 2 is a right side elevational view thereof; and,

FIG. 3 is a rear elevational view thereof.

The broken line showing of environmental structures in FIGS. 1-3 is for illustrative purposes only and forms no part of the claimed design.

A characteristic feature of the design resides in continuous, overlapping circular beads which are visible through a spiral wrap.

Rao, Prabhakar B., Castellanos, Edwin A.
