Product review (3 stars): General Electric MWF Refrigerator Water Filter
The noticeable thing to me about this filter is that it does take the chlorine taste out of the water. They recommend that you change the filter every 6 months. I don't use much water out of the refrigerator dispenser and I don't change the filter that often, maybe once a year. I have good city water and it seems to take out the chlorine out of the water. I don't know if there is any danger to that.
