LG Refrigerator Water Filters

LG has used five twist-in water filters across its dispenser refrigerators since 2008. The LT500P and LT600P appear on spec sheets from 2008 to 2015, the LT700P on three-door French door models from 2010 to 2018, the LT800P on side-by-side and four-door models from 2015 on, and the LT1000P on models from 2017 on, including the current lineup. All five install with a twist and LG rates each at six months, but LG's spec sheets assign every model exactly one of them.

Each of the 36 LG models below names its filter from LG's own spec sheet, and the 5 filter pages list every LG part number the filter is sold under. One-letter differences matter: the LFX28968 takes the LT700P and the LFXS28968 takes the LT1000P, and the LMX25964 and LMX25985 from the same year take the LT500P and LT600P.
