Filter Replacement
The contaminants or other substances removed or reduced by
this water filter are not necessarily in all users’ water.
Filter life varies depending on local water conditions and the
volume of water used. We recommend that you change your
filter as prescribed by the filter documentation, however, it can
be replaced earlier if there is a drop in water pressure.
You can use a variety of Whirlpool filters with this housing

:
WHKF-GD05, WHKF-WHPL, WHKF-WHSW, or WHEF-WHWC.
Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after
the system.
