LG LT1000P vs LT700P vs LT800P: which filter does your fridge need?
Quick answer: The LG LT1000P fits refrigerators made after 2018 (push-in, upper interior). The LT700P fits 2010–2018 models (twist-in, upper interior). The LT800P fits bottom-freezer models with a grille filter. Check your current filter label for the exact part number before ordering.
LG makes great refrigerators — but finding the right water filter can be surprisingly confusing
Three part numbers. Similar names. And if you pick the wrong one, it simply won’t fit. This guide breaks down the differences between the LG LT1000P, LT700P, and LT800P so you can order with confidence.
The quick answer: how to find your filter in 30 seconds
Open your refrigerator door and look for the filter compartment — usually in the upper-right corner of the fridge interior or in the bottom grille. The current filter will have a label with the part number printed on it. Match that number to the guide below.

Still not sure which one you need?
The safest method: remove your current filter and read the part number directly off the label. LG part numbers always start with “LT” followed by three digits. If you see “ADQ” — that’s the same filter with an alternate part number.

Frequently asked questions
Is the LG LT1000P the same as Kenmore 9980?
Yes. The LG LT1000P and Kenmore 9980 are the same filter. Kenmore refrigerators made by LG use LG part numbers with a Kenmore label. Either version fits the same fridge models.
Can I use an LT1000P instead of an LT700P?
No. Despite looking similar, the LT1000P and LT700P use different mounting systems and are not interchangeable. Always match the part number on your existing filter.
Where is the filter on an LG bottom-freezer refrigerator?
On LG bottom-freezer models, the water filter is located in the lower-left section of the bottom grille — outside the main refrigerator compartment. This is the LT800P housing.
How often should I replace my LG refrigerator water filter?
LG recommends replacing every 6 months or 200 gallons, whichever comes first. The filter indicator light on the control panel will also alert you when it’s time.
