Product review (2 stars): Make sure you are getting the filtration level you want.
This is a basic water filter for taste and is not the same in what it filters out as the original UKF8001 or the new EDR4RXD1 which are 3 stage filters and filter out 23 contaminants.  It will fit in the refrigerator as the UKF8001 but it does not have the same high quality NSF certification to reduce 23 contaminants.  That filter is around $47- $50, you get what you pay for.
