Product review (1 stars): Awful taste and not sure this is a geniune product.
While this fit our Kitchenaid refrigerator, the taste of the water is awful. We have used it for over a month with no improvement and this is after dozens of gallons of water have been filtered through it. If I leave a glass of water sitting for a couple of hours, you can taste a distinctive glue-like taste that initially is a little like bitter lemon. I have gone back to bottle water and am filling the ice bin with store bought ice for now. I paid for this better filter to try and reduce contaminants for a member of our household who has immune problems. I am seriously concerned that using this filter is actually making this person sicker! I flushed and cleaned the entire refrigerator water system without the filter, and then reinstalled, but the taste is still there. I cannot recommend this filter. If I had not thrown out the original box, I would definitely return this item. Furthermore, I didn't realize I was buying the filter from an appliance store; should have checked that it was direct from Whirlpool. Don't know if that contributed to the problem or not, but this filter is trash.
