Product review (5 stars): Appear to be a direct replacement
What can you say about a water filter?  These appear to be a direct Whirlpool replacement.  These are not super filters rather a filter with a charcoal back, that helps the ice maker make clear ice and the water to taste much better.

I am sure other reviewers can point out issues relative to these but for the money and their ability to work, I have no complains and will purchase them again.
