Product review (4 stars): This filter is a replacement for the original Whirlpool filter ...
This filter is a replacement for the original Whirlpool filter. It does not have the alignment marks that the Whirlpool filter has and when installing, the lack of marks is irritating. The brand new filter initially spewed out a lot of greyish material and the first half gallon or so of water was cloudy. After that it seems to have settled down.
Cost wise these are more affordable than the Whirlpool filters. Hopefully they will work as well. Time will tell.
