Product review (5 stars): Excellent filter; 3 month life; here's the issue...
The GE MWF refrigerator filter is an excellent filter rating NSF-53 which means it removes chlorine and particulate and a whole host of other dangerous toxins. Some negative posters have stated that they only got one month life. The problem is that this filter only has a 3 month expected life which will be cut far shorter if the water supply is high in particulate. At $40 per filter (from GE), that gets pretty expensive. In order to lengthen the life of this filter, purchase a cheap Dupont NSF-42 in-line 6 month refrigerator filter from W-M -- $10.00 -- and place behind the refrigerator. The cheap filter will handle the particulate and possibly double the life of your GE NSF-53 filter to 6 month. So in the end, you save $30 every six months, or more depending on the quality of your water supply. I highly recommend this GE filter, despite the international markings. They all come from the same factories, same design.
