Product review (5 stars): Good budget alternative replacement filter for Whirlpool 4396701
We replaced a name brand Whirlpool 4396701 filter that cost around $50 with the Icepure model and so far it's working great.  I haven't the means or the desire to administer a comparative analysis of the water quality though both filters, but I think the it tastes the same.  Until I see some evidence that the Whirlpool model is three times better I'll continue to buy the Icepure at a third of the price.
