Collected by FiltersFast.comI have a well in Florida that has no other filter than the filter in the LG refrigerator. I have been ordering these filters from FiltersFast.com for 5 years and have had no issues. I can go about a year on this filter (it is suggested every 6 months by LG) for a family of 4. We use the refrigerated water probably 25 times per day. I noticed I can't go much more than a year without a replacement so I set up auto-ship which is a great feature.
