Product review (5 stars): Very good value
I have a GE side-by-side fridge and this filter is a perfect replacement for the GE MWF filter. Fits great and is rated for 6 months or 300 gallons - about twice the GE rating. I have never tested the water, but I assume the filter is functioning well  - the water tastes and smells much better than unfiltered tap water. The other big plus is the 3 pack cost is significantly less than the GE brand. I would definitely recommend this product.
