Why

✓ LG LT800P refrigerator water filter is listed as the original (OEM) part for this model.

Good to know

LG LT800P: replace every 6 months or 200 gallons (LG). LT700P, LT800P and LT1000P are separate LG part numbers. Buy the one listed for your model. GOTCHA: a retailer lists LT1000P for sibling LSXS26336S, but LG's own spec sheet for LSXS26336 says LT800P.
