Product review (4 stars): Filter's better than Britta Pitcher
A Lowes salesperson did a comparison evaluation on our tap water, Britta pitcher, and refridgerator water in an effort to sell us an RO system.  The RO system was the best, of course, next best was water from the fridge using this filter.  The filter is a pain to install, but that's the fridge, not the filter.  Also, for a family of 3 with daily use, the filter lasts about 6 months.  (We use the Britta to get filtered water for cooking.)
