Product review (5 stars): Fridge water filter
Works as good as the $50 one. I can't tell the difference other than the color. Same Whirlpool people! I will definitely buy the cheaper one next time.

PS I saw some earlier negative notes about it and I'm wondering if the people didn't flush it out with 4 gallons of water first. It doesn't state that on the filter or box but the more expensive one did so I flushed it anyway. Water is pure and taste fine.
