Product review (5 stars): Works as Factory - At Half the Price
This is 'Compatible' to the factory filter. My LG fridge is about 8 years old and I am on a private well. My water is very good but contains a significant amount of rust and is hard. It also is quite alkaline as well. My old filter began to slow the flow of water so I went to the local orange box store to purchase a replacement. The factory filter was $49.95. Nope - not this boy is gonna pay 50 bucks for a water filter. I check Amazon and purchased this knockoff. I is a perfect replacement and after running a few gallons of water through it, I can't tell the difference. The water I did run through was nasty however. It was dark with a lot of particulate in it. I assume this was displaced from my water line on the filter change.

I dumped the ice in the ice maker and started over. All is well and I have about $26 extra in my wallet and a new filter. Thanks

7-2017 update - I replaced this filter with an identical filter.  I don't think it needed replacement but I did it anyway since I changed the water valve on the fridge.
