Product review (5 stars): this filter seems to filter water better than the "old" Pur filters Whirlpool sold
While some of complained about the taste from this "new" version of the Whirlpool filter, I didn't notice any taste after flushing about 1.5 gallons of water after installation.  In fact, this filter seems to filter water better than the "old" Pur filters Whirlpool sold.  The old filters would still leave some tap water taste, while this new version leaves the water essentially tasteless.  Also, I found that these new versions were slightly less expensive than the prior versions.
