Product review (1 stars): The old saying, "you get what you pay for," may not even apply here.
Prior to purchasing this filter, I had been quite satisfied with the LG 5231JA2006A filter.  I gave this "USA-made" filter a try since Amazon directed me to it when I searched for the LG 5231JA2006A filter. No LG-made filters were offered as an option.  After trying it, YUK!.  Sure this filter is cheap compared to the LG-made filter, but the one I received does not produce drinkable water.  So, I checked Amazon, read the reviews and now I see that others also are disappointed with it. I went to the LG website and found that the LG filter 5231JA2006A is now called the LT600P - and is available at a 15% discount if you sign up for a 3 or 6 month subscription. When I searched Amazon for the LT600P filter, the filter is available on Amazon, and subscription is available, but it is $5 more expensive than if purchased directly from LG. Bottom line, the LG-made filter LT600P costs more than this supposedly "USA-made" replacement filter, but it actually works, and is available for $5 less when purchased directly from LG.
