Product review (5 stars): why spend the extra money
I bought this LG filter to replace the one that came in the fridge. Locally they wanted $50 for this filter. This works just as well. One thing I do to make them last longer is prefilter it with an under cabinet sediment/taste filter. The water coming out of the fridge tastes great. I generally get 2 years out of one of these due to the prefilter idea.
This is a direct replacement and was easy to install.
