Product review (5 stars): Original filter at a good price
These filter are actual GE product, the original.  This seller provided a great deal on these.

By the way, you should replace your filters every 6 months. I really didn't believe this was true, and is just a ploy by the manufacturer to get you to buy more replacement filters.  However, the quality/taste of the water definitely degrades after 6 months. It is night and day in taste,  before and after you replace your old filter.
