Product review (4 stars): Cost-effective, easy, good tasting water!
For those that would usually order the GE MWF filter, this is an excellent, cost-effective alternative. It's essentially the equivalent of a Brita filter built into your fridge. It removes impurities and sediment in your water that make it taste bad. Installation is fairly easy - place a small bowl underneath the filter (to catch any water that may spill during removal), turn, remove, place new filter, turn. Run about two gallons of water through, and you're all set.

Side note: the manufacturer specifically notes that this should not be used to filter "unsafe" water. If you live in an area where the safety of the water you drink is questionable, this is probably not the product for you. I use this to filter out the chlorinated taste of public water.
