Product review (5 stars): Perfect fit for my Whirlpool
These are the exact same filters as the one that came with my Whirlpool Refrigerator.  They fit perfectly and they go in with ease.  They last 6 months and I am hoping my refrigerator lasts a few more years, so I have enough for four years.

As you can see from my uploaded photo, these filters are exactly the same as my original... the one on the right is the original, the one on the left is the new one and as you can see, I received 8 with my purchase!
