Product review (4 stars): Not bad... short life span
Bought this to replace the same filter that came with the fridge.  LG recommends these be replaced every 6 months, but I find that I was able to get a little more out of these (8 months).  I will say once you replace it, you really can tell the taste difference with a new filter.  I do wish these had the capability to last a bit longer (yearly perhaps?) as they are a bit pricey.
