Product review (5 stars): Waterdrop MWF refrigerator filters
I have always used the (much) more expensive GE version of this refrigerator filter - apparently for no valid reason.  This filter works great, and the water and ice cubes are just as clear, taste free, and clean as when using the more expensive brand.  It should be noted that I do not have well water which other reviews say require the more expensive filters.  With city water, these provide excellent filtration and I would highly recommend them.
