LG LT700P Water Filter: Complete Replacement Guide + Best Compatible Options (2025)
LG LT700P Water Filter: Complete Replacement Guide + Best Compatible Options (2025)
If your LG refrigerator was manufactured between 2014 and 2018, the LG LT700P is almost certainly the filter you need. It is the predecessor to the LT1000P — and while LG has moved on to newer designs, millions of households still depend on this filter every day, often paying OEM prices when certified compatible alternatives cost less than half as much.
Also known as: ADQ36006101, ADQ36006102 | Type: Twist-in internal | Location: Upper right of fridge interior | Life: 6 months / 200 gallons | Certifications: NSF/ANSI 42 and 53
ADQ36006101 vs ADQ36006102 — What Is the Difference?
This causes significant confusion among buyers — the answer is simple. Both are part numbers for the LG LT700P filter. ADQ36006101 is the original engineering number; ADQ36006102 is a minor housing revision introduced later. They are completely interchangeable and fit all the same LG refrigerators. When you order an LT700P compatible today, you receive the ADQ36006102 specification.
The LT700P (2014–2018) and LT1000P (2018+) are NOT interchangeable. Different dimensions, different thread pattern. Installing the wrong generation will cause leaks or no water flow. Check your existing installed filter label to confirm your generation before ordering. For the LT1000P, see our LG LT1000P complete guide.
Which LG Refrigerators Use the LT700P?
The LT700P was used in LG refrigerators produced from approximately 2014 to 2018. Primary series include LFXS, LSXS, LFX, and early LRMVS models. The fastest confirmation is the label on your installed filter. Use our Filter Compatibility Checker to verify by model number.

How to Install the LG LT700P — Step by Step
Locate the Filter
Open the refrigerator and look in the upper right interior corner of the fridge compartment for the cylindrical filter housing.
Turn Off the Ice Maker
Lift the ice maker arm to the off position inside the freezer to prevent water demand during the swap.
Remove the Old Filter
Grip the filter body firmly and rotate counterclockwise approximately a quarter-turn until it releases. Pull straight out. Have a towel ready for a small drip.
💡 If stuck, wrap the filter in a rubber band for grip. Apply steady pressure — never jerk or force.Remove the Protective Cap
Unpack the new LT700P. Remove the plastic protective cap from the O-ring end before inserting. Leaving it on causes leaks — this is the most common installation mistake.
Insert and Lock
Align the filter with the housing notch. Push in and rotate clockwise approximately a quarter-turn until you feel a solid locked stop. No wobble when correctly seated.
Flush 2–3 Gallons and Reset
Run the dispenser for 4–6 minutes, discarding the water. Then press and hold the Water Filter button on your LG display for 3–5 seconds to reset the indicator light.
Low Water Flow After Installing LT700P — Troubleshooting
- O-ring cap still on: Remove the filter and confirm the protective cap is fully off
- Filter not fully locked: A partial quarter-turn leaves the valve partially closed — remove and reinstall firmly
- Needs flushing: Run 3 full gallons before measuring flow — carbon particles temporarily restrict flow
- Low home water pressure: LG requires minimum 20 PSI — check at the supply valve behind the fridge
- Kinked supply line: Pull the fridge out and inspect the water line for kinks
OEM vs Compatible LT700P — The Numbers
At $42.99 OEM vs $17.95 compatible, you save $25 per filter or $50 annually at the recommended two-per-year schedule. Over 5 years that is $250 in savings for water that tests identically under NSF International certification standards.
