Product review (5 stars): So far so good my LG Refridgerator Model LFX33975ST did acknowledge this filter
So far so good my LG Refridgerator Model LFX33975ST did acknowledge this filter.  Did flush only a 1/2 gallon to clear the water.  Water taste great and is crystal clear.  I will update in 6 months if there are any problems.  So far very happy and will buy again!!!
