Product review (1 stars): Suspected counterfeit, but cannot return!
I bought 2 of these on Jan. 2016 and it's now mid March 2016, and I 've already gone through both of these filters because each of these didn't last 6 months as it should. Meaning the taste and odor of water changed within a couple months.  They were for a brand new refrigerator and I had before the same LG fridge which required the same LG filter and had no problem with the filters from Amazon before. Still being offered as Amazon Prime, these particular items(X000X1578H) have slightly different item number than the ones I've previously purchased(X000YJE2WP) a couple years back. After reading reviews, I suspect that item X000X1578H might be the counterfeit. I just received the LG filter(X000YJE2WP) which I've reordered from my order history 2 yrs back and comparing side by side of the items doesn't tell much striking differences except for a number code inscribed on the bottom portion of the filter's main body which the suspected counterfeit(X000X1578H) doesn't have. They are not returnable because the return window has been closed.
