Product review (5 stars): Much better than old version Mode # UKF8001
Perfect fit replacement for old version UKF8001.  Water flow is better that old version UKF8001.  I was skeptical about going from old model to current version.  Wow!  very glad I did.  Don't buy the old version.  Get this current one for the better flow alone.  And if you are into the filtering aspects as well, and if you can believe labels on stuff you can't see, the new version also removes more contaminants than the old version.
