Product review (5 stars): Great Replacement Filter!
I bought these filters because I could no longer find the replacements made by Whirlpool for my Whirlpool filter.  I installed one of the filters and think that it works better than the brand-name filters that I had always used.  I am very pleased with the product.  In addition, it was nicely packaged and shipped promptly.  I will definitely order more from this seller.
