Product review (3 stars): Expensive and exploring alternate choices!
A rather expensive item to replace every six months if it's your sole source of water filtration. However, for my refrigerator's ice maker/water unit and drinking water at the kitchen sink I have installed a two stage water filter mounted in the basement ceiling. This unit does most of the work and is rated to process 1600 gallons of water. The LG unit has similar quality specifications and therefore having a substantial longer use life.

I would have considered a generic brand if this was my sole filter and it was equal in filtering specs and certified by one of the national testing laboratories. This would be because of the need to replace it more often and if cost was an issue.
