Product review (1 stars): If you like swamp water, order this!
I will not purchase this filter ever again.  It was such an unpleasant experience; I wouldnt even use it if Whirlpool sent a free lifetime supply.

I ran an initial 6 gallons of water through the filter upon installation. Each glass of water was crystal clear BUT had a very unpleasant odor that assaults your nose and tastes like you dipped your tongue in a hot swamp.  I thought that maybe this was because it needed to be flushed with more water; however, that was NOT the case after running a total of 10+ gallons through it...It still tasted and smelled like swamp water.  For how much they charge, you think you're getting a quality product (heck, for $45, you might even think the filter houses magical miniature unicorns that manufacture fresh-water pee!) but the reality remains that this is not the quality filter I was looking for.

The 1 star is for the filter housing.  It's nice and streamlined looking.  Too bad they didn't invest as much thought in quality filtration.
