Product review (4 stars): Seem fine.
I have little to no experience regarding the filters.  Replacing the factory installed ones 6months after purchase because my LG Refrigerator is blinking at me to do so.  Fit fine.  Individually wrapped carbon filter, packaged in small zip lock bags.  From experience with fish filters/water filters I think they should be sealed/airtight or the carbon will loose effectiveness, so not so sure about the zip lock bags.  New packaging.  Have not noticed any difference in smell in the inside of the fridge before replacing filter - will monitor for after installing. .  If bad or inferior will update review.
