Product review (5 stars): Great Filter
Works great, and I've never had any problems with these.  Water comes out clear and tastes great.  I've seen several people complain on here of cloudy water, but I've never had this issue.  The only thing I can think of is that they're not following the instructions on the package, which clearly state that you need to run 4 gallons of water through after changing the filter out.  If they're not doing this for whatever reason, then yes - the water probably will be cloudy.  The only complaint I have is that I feel they're a little expensive.
