Product review (5 stars): Better than original?.?.?
I bought this to replace the manufacturer filter in my LG fridge.  I let the first one go for about 18 months.  I started to taste a difference.  When we used this filter (which cost a lot less than the manufacturers replacement filter) the taste was gone.  I might even say it was better than before.

I will say this though.  I bought the double pack to save money, and only got 1 shipped to me.  I called amazon and it was corrected immediately.  But that doesn't have any real bearing on how it works.  Just added FYI.
