LG LT1000P - 6 Month / 200 Gallon Capacity Replacement Refrigerator Water Filter (NSF42, NSF53, and NSF401) ADQ74793501, ADQ75795105, or AGF80300704 , White

The LG LT1000P refrigerator water filter is a legit LG filter with a 6 month/200 gallon capacity. It is certified by NSF International against the same NSF/ANSI Standard 42, 53, and 401 as other LG filters, including the LT1000PC and LT1000PCS. The filter is made in South Korea and generally easy to install, although some models may require a water bypass plug that initially comes with the refrigerator. The LG filter is more expensive than some non-LG alternatives but likely filters water better and for longer. However, some customers have had issues with the filter's taste and lifespan, especially when using an aftermarket filter or combining with a water softener.
