Product review (5 stars): Good news, it fit perfectly and is working just ...
In the past I always purchased Whirlpool replacement filters from a local appliance repair store.  For years, I would spend $30-40 dollars for just one filter.  I recently decided to search Amazon and found EcoAqua filters.  I was able to buy a pack of three filters for less than what I spent on one.  Of course, when the package arrived, I wasn't sure if these filters would fit my Whirlpool refrigerator.  Good news, it fit perfectly and is working just fine.  I highly recommend this filter - it saved me money and was delivered right to my house!
