Description



This application is related to copending U.S. application Ser. No. 29,361,828, filed concurrently herewith and entitled "Filter Cartridge Assembly," U.S. application Ser. No. 29/361,826, filed concurrently herewith and entitled "Filter Cartridge," and U.S. application Ser. No. 29/361,824, filed concurrently herewith and entitled "Filter Cartridge," the disclosures of which are incorporated herein by reference.

FIG. 1 depicts a top plan view of a filter cartridge having the claimed ornamental design;

FIG. 2 depicts a bottom plan view of the filter cartridge of FIG. 1, showing the bottom side of a filter cartridge having my design;

FIG. 3 is an elevation view from the right side of the filter cartridge of FIG. 1, showing the right side of a filter cartridge having my design;

FIG. 4 is an elevation view from the left side of the filter cartridge of FIG. 1, showing the left side of a filter cartridge having my design;

FIG. 5 is an elevation view from front or back side of the filter cartridge of FIG. 1, showing the front or back side of a filter cartridge having my design;

FIG. 6 is a perspective view of the filter cartridge of FIG. 1, showing the top and sides of a filter cartridge having my design;

FIG. 7 is a perspective view of the filter cartridge of FIG. 1, showing the bottom and sides of a filter cartridge having my design; and,

FIG. 8 is a perspective view of a filter housing having several filter cartridges of FIG. 1 installed therein. The housing is shown in phantom for environmental purposes only and forms no part of the claimed embodiment. The filter cartridges are shown in phantom except one because the filter cartridges' appearance within the filter housing are not a part of the claimed ornamental design of this application.

It should be understood that the labels used herein for describing orientation (e.g., front, rear, top, bottom, left, and right) are merely for reference, and the design may be disposed in any manner and still be within the scope of the present invention.

The design is shown broken away along its length to indicate unspecified length.

The broken line showing of unclaimed portions of the filter cartridge forms no part of the claimed design.
