The ornamental design for a waterfilter, as shown and described.
FIG. 1 is a top-front perspective view of a water filter according to an embodiment of our design;
FIG. 2 is a top-rear perspective view thereof;
FIG. 3 is a top view thereof;
FIG. 4 is a bottom view thereof;
FIG. 5 is a rear elevation view thereof;
FIG. 6 is a front elevation view thereof; and,
FIG. 7 is a right side elevation view thereof; a left side view being a mirror image thereof.
The broken line showings are of portions of the water filter that form no part of the claimed design.
Dash-dot lines adjacent un-shaded areas represent bounds of the claimed design and form no part of the claimed design themselves.
The pairs of closely adjacent, spaced jagged broken lines in the drawings form no part of the claimed design and the portions between such pairs of jagged broken lines are broken away to disclose indeterminate length. Portions of the design that may be visible between the jagged lines have been removed for clarity.
