Product review (5 stars): Water Filter Trial-First Trail of the this brand of filter.
The box of filters arrived as scheduled, in perfect condition.  I installed one of the filters in the GE Refrigerator.  It installed with no problems, and is working with no problems.  The question that I do not have an answer to is, "Is the filtration effective"?  All I know is that the water and ice cubes taste fine and appear fine.  I do have an all house carbon filter ahead of the refrigerator so that the water is actually double filtered.  I am trusting that the filtration is good and that all impurities have been removed. The truth is, that I trusted the GE filters as well.  These filters are considerably less expensive than the GE filters.
