Product review (1 stars): After following all the instructions correctly for replacing this water filter it was indeed a bad purchase.
I read both the negative and positive reviews and came to the conclusion that the negative reviewers did not flush the system first as commented rather critically by one reviewer. I bought the product anyway. It is indeed terrible! I flushed 5 gallons after installing it and then another after my first glass of water. I let it rest overnight and still had water that was cloudy and tasted terrible. The next day I compared the glass of water from my tap to the glass of water from this filter, and the tap water is clear and tastes much better. The filtered water is still terrible. It is possible that these are different lots and the brand is a good one, but i will not be buying anything with this brand again. I use my dispenser continually and am not happy looking for and then buying another filter.
