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.
