Product review (1 stars): Avoid if you want filtered water.
This filter is terrible.  I first saw these being sold on Woot, and figured they would be worth a try to save a few dollars.

First thing I noticed is the filter is very light.  It was easy to install and fit perfectly.  We ran about 5 gallons of water through it to remove any charcoal, etc.  The water tasted great at first, but within a few days the tap water taste returned.  I have no confidence that these filters actually filter anything.  I'm in the process of installing a reverse osmosis system so i can filter more than just water to my refrigerator.

Stick with LG brand filters.
