Product review (5 stars): great product must buy from amazon
This filter is same as what whirlpool is selling.  The only difference is whirlpool puts there label and sell it for $ 40 + tax+ shipping.  I was a little hesitant about this before placing the order. But totally satisfied when i saw my old whirlpool filter and this one next to each other.

Great way to save 15$, buy it from amazon instead of whirlpool
