Product review (5 stars): General Electric MWF Refrigerator Water Filter
I have purchased this product for the past 6 years and never had a problem. when the water runs slow I replace the filter and it last aprox. 3 months to 4 months although it says 6 months.  I believe it depends on how much you use your water filter.  I use it all the time I never buy bottled water anymore.  I use it to make my coffee, tea, hot choco and hot cereals.  Hope this review helps also the I usually buy the 3 pact so I am never without my Water Filter.  Shipping and delivery is great on Amazon never a problem.
