Product review (5 stars): For the LG LFX25991 refridgerator
I'm giving this five stars because the alternatives are not great. We bought a "knock off" version of this filter because it claimed to work as well as the OEM filter but it definitely did not. I live in Los Angeles and the chlorine taste in the water is very strong. With the cheap filter, you could still taste it. In fact, it didn't taste like it was filtering the water at all. So I got this one, installed it as instructed and in no time my water was back to tasting like bottled drinking water.

The price on these can be a little high but considering I no longer buy bottled water or bags of ice, it pays for itself. And there's nothing like fresh, cold and filtered water.
