Your LG refrigerator works hard every day to keep your family hydrated with clean, great-tasting water and ice. Getting the right replacement filter confirmed before you buy is the single most important step in maintaining that performance. If you are looking at the part number LT700P and are not completely sure it is the correct replacement for your unit, this guide will walk you through exactly how to check compatibility before buying so you can order with confidence and avoid a costly mismatch.
Why LG Refrigerator Water Filter Codes Can Be Confusing
LG produces refrigerators across multiple series and generations and different configurations use different water filter formats. Here is why buyers frequently run into confusion when searching for the right LT700P replacement:
- The LT700P, LT800P, and LT1000P all look physically similar and all use twist-in designs, making it impossible to tell them apart by appearance or installation type alone
- Alternative part numbers ADQ36006101 and ADQ36006102 appear on older LT700P filter labels and buyers searching for these codes may not immediately find the LT700P as the correct current replacement
- The LT700P covers an earlier generation of LG refrigerators than the LT800P and LT1000P, so buyers who search broadly for an LG water filter often land on the newer filter codes without realising their refrigerator requires the LT700P
- All three filter codes carry the same NSF 42 and 53 certification and the same 200 gallon or 6 month service life making them appear interchangeable in listings when they are not
- Some product listings group multiple LG filter codes together making it unclear which code is the primary replacement for a specific refrigerator model generation
Where to Find Your LG Refrigerator Filter Part Number Before Buying
- Check the label on your current filter — the part number is printed directly on it. This is the fastest and most reliable confirmation
- Look inside the filter housing slot — some LG models print the required filter code on a label inside the housing slot itself inside the fresh food compartment
- Find the model plate inside the fridge — typically located along the upper door frame or side wall of the fresh food compartment. Use the model number to cross-reference the correct filter code
- Check your user guide — the maintenance section lists the exact replacement filter code for your specific LG refrigerator model
- Search by model number on the retailer page — if the label is worn or unreadable this is the quickest way to confirm the right filter before you buy
What Is the LG LT700P Water Filter?
The LG LT700P is an NSF 42 and 53 certified replacement water filter designed for a specific range of LG refrigerator models. It uses activated carbon block filtration to reduce chlorine taste and odor, lead, heavy metals, and VOCs before water reaches the dispenser or ice maker. The LT700P has a service life of 200 gallons or 6 months whichever comes first and uses a twist-in installation design that requires no tools. Alternative part numbers ADQ36006101 and ADQ36006102 refer to the same LT700P filter format and commonly appear on older filter labels in earlier LG refrigerator models.
What Is the LG LT800P Water Filter?
The LG LT800P is also an NSF 42 and 53 certified activated carbon block replacement water filter but is designed for a newer generation of LG refrigerator models than the LT700P. It carries the same service life and uses the same twist-in installation design but has a housing format that is not interchangeable with the LT700P. If your existing filter shows LT800P or any of its alternative codes, the LT700P is not the correct replacement for your unit.
What Is the LG LT1000P Water Filter?
The LG LT1000P is the latest generation LG refrigerator water filter, also NSF 42 and 53 certified with the same 200 gallon or 6 month service life and twist-in installation design. Like the LT800P, the LT1000P uses a housing format specific to its compatible model range and is not interchangeable with the LT700P or the LT800P. If your existing filter shows LT1000P or ADQ747935, the LT700P is not the correct replacement for your unit.
Is the LT700P the Same as the LT800P or LT1000P?
No. This is one of the most common questions buyers ask when searching for an LG refrigerator water filter. While the LT700P, LT800P, and LT1000P are all NSF 42 and 53 certified activated carbon block filters with the same service life and the same twist-in installation design, they are separate part numbers with different housing tolerances built for different LG refrigerator model generations. Ordering the LT800P or LT1000P for a refrigerator that requires the LT700P will result in a filter that either does not seat properly or leaves gaps at the housing connection that allow unfiltered water to bypass the filter entirely. Always confirm the part number on the existing filter before placing your order.
Compatibility Checklist Before You Buy the LG LT700P
- Your current filter label shows LT700P, ADQ36006101, or ADQ36006102 — the LT700P is the confirmed replacement for your unit
- Your refrigerator model appears on the LT700P compatibility list — cross-check your model number before ordering
- Your refrigerator is an LG French door or side-by-side model from the standard generation — the LT700P covers select configurations within these series
- Your current filter does not show LT800P or LT1000P — if it does those are the correct replacements for your unit not the LT700P
- Your current filter uses a twist-in connection — the LT700P is twist-in only
- It has been 6 months or 200 gallons since your last replacement — if yes it is time to order regardless of how the water currently tastes or flows
Common Mistakes When Buying the LG LT700P Water Filter
- Ordering the LT800P or LT1000P because they are more commonly listed — the LT700P covers a specific range of LG models. Refrigerators that require the LT700P will not accept the LT800P or LT1000P even if those filters appear to be a similar size and shape
- Assuming ADQ36006101 and the LT700P are different filters — they are not. ADQ36006101 and ADQ36006102 are alternative part numbers for the same LT700P filter. If your label shows either of these codes the LT700P is the correct replacement to order
- Confusing the LT700P water filter with the LT120F air filter — both follow the LT naming convention but serve completely different functions. The LT120F is an air filter for the refrigerator compartment while the LT700P filters dispensed water and ice
- Ordering based on appearance rather than part number — the LT700P, LT800P, and LT1000P look nearly identical but have different housing tolerances that prevent cross-code substitution
- Skipping the post-installation flush — always run 2 to 3 gallons through the dispenser after installing a new LT700P to clear carbon fines before drinking
- Forgetting to reset the filter indicator — an unreset indicator will trigger a false early replacement reminder even when the new filter is performing correctly. Reset the indicator per the LG user guide immediately after installation
When Should You Order a Replacement LG LT700P Filter?
- 6 months have passed since the last replacement — the primary trigger regardless of gallon count or water quality
- 200 gallons have passed — replace at this threshold if your household reaches it before the 6 month mark
- Water tastes flat or slightly chemical — the carbon block is no longer reducing chlorine and contaminants at full capacity
- Ice has a chlorine or off taste — a reliable sign the filter is past its effective odor and contaminant reduction life
- Water flow from the dispenser has slowed noticeably — a saturated filter restricts flow through the housing
- The filter indicator light has activated — order a replacement promptly rather than waiting for additional signs of reduced performance

FAQs
How do I know if my LG refrigerator needs the LT700P and not the LT800P or LT1000P?
Check the part number on the existing filter currently installed in your refrigerator. If it shows LT700P, ADQ36006101, or ADQ36006102, the LT700P is the confirmed replacement. If it shows LT800P or LT1000P those are the correct filters for your unit instead.
Can I use the LT800P instead of the LT700P if my refrigerator model is older?
No. The LT700P and LT800P have different housing tolerances and are not interchangeable despite sharing the same certifications and installation design. Always replace with the same part number as the filter currently installed in your refrigerator.
Do I need to turn off the water supply before replacing the LT700P?
The twist-in housing on the LT700P is designed for a straightforward swap on most compatible LG models without requiring the water supply to be shut off. Some minor dripping at the housing during the swap is normal. Consult the LG user guide for your specific model if you are unsure.
Is the LG LT700P available in a multipack for households that replace filters frequently?
Check the product listing on the shop page for multipack options. Buying in a multipack is a practical option for households that replace the filter at or before the 6 month mark and want to keep a spare on hand to avoid any gap in filtration performance.
Why does my water still taste off after installing a new LT700P filter?
Running 2 to 3 gallons through the dispenser after installation flushes carbon fines and trapped air from the new filter and typically resolves any residual taste issues. If off taste persists beyond the flush cycle confirm the filter is fully locked into the housing and that the filter indicator has been reset.
Where can I find more detail on how the LT700P compares to the LT800P and LT1000P before I buy?
The LG LT700P landing page includes a full head to head comparison table covering the LT700P, LT800P, and LT1000P side by side to help you confirm the correct filter before ordering.
