Product review (4 stars): GREAT FILTERS!
I think these water filters are great.  I have been using them for over 2 years.  I can definitely tell the difference in the taste of my water. However if you want a filter that is more that NSF 42 and NSF/372 certified, you'll have to stick with similar brands that come with your original appliance....hence the 4 stars. Those can cost more because they remove more contaminates.  But nonetheless I have enjoyed using these because they do control chlorine and the charcoal giving a refreshing taste.  You can also contact the Water Quality Association on the web to find out the certification to any filter you choose.  So drink up and cheers!
