LG LT1000P vs LT800P Refrigerator Water Filter

This is the most important section if you are unsure which LG refrigerator water filter to order.

How do I check my current filter part number?

The part number is printed directly on the filter currently installed in your refrigerator. The filter housing is typically located in the upper right corner inside the fresh food compartment. Remove the existing filter and check the label before ordering to avoid a mismatch.

What happens if I order the wrong filter?

An incorrectly ordered filter will not seat properly in the housing and will not deliver effective water filtration. In some cases it may appear to fit but leave gaps at the housing connection that allow unfiltered water to pass through to the dispenser and ice maker. Always order by part number rather than by appearance or size.

How Often Should You Buy a Replacement LG LT1000P Filter?

Order a fresh LT1000P every 6 months or 200 gallons, whichever comes first. Households with higher water consumption may reach the 200 gallon mark before the 6 month period is up. A saturated carbon block past its service life stops reducing chlorine, lead, and VOCs effectively and may begin releasing previously captured contaminants back into the water. Replacing on schedule rather than waiting for taste or flow changes maintains consistent filtration performance through the full service life.

How to Install the LG LT1000P Refrigerator Water Filter

1. Locate the filter housing inside the LG refrigerator fresh food compartment, typically in the upper right corner
2. Twist the old filter counterclockwise until it releases from the housing
3. Pull the old LT1000P filter straight out
4. Align the new filter with the housing inlet and insert it firmly
5. Twist clockwise until it locks securely into position
6. Run 2 to 3 gallons of water through the dispenser before drinking
7. Reset the filter indicator light per the LG refrigerator user guide

FAQs

Where can I buy the LG LT1000P refrigerator water filter?

You can order the LG LT1000P directly from the shop link on this page. Confirm the part number against your existing filter label before completing your purchase to avoid ordering the wrong filter for your model.

Is the LG LT1000P the same as the LT800P water filter?

No. The LT1000P and LT800P are separate part numbers with different housing designs built for different LG refrigerator model generations. They are not interchangeable. Always confirm the correct part number for your specific model before ordering.

Is the LT1000P the same as ADQ747935 or MDJ64844601?

Yes. ADQ747935 and MDJ64844601 are alternative part numbers that refer to the same LT1000P filter format. If your refrigerator currently shows either of those codes on the existing filter label, the LT1000P is the correct replacement to order.

Does the LG LT1000P filter water going to the ice maker as well as the dispenser?

On most compatible LG refrigerator models the LT1000P serves both the water dispenser and the ice maker from a single filter housing. Confirm this against your specific model in the LG user guide to verify whether the LT1000P covers both functions on your unit.

Why is my water flow slow after installing a new LT1000P filter?

Slow flow immediately after installation is usually caused by air trapped in the filter or housing during the swap. Running 2 to 3 gallons through the dispenser clears trapped air and carbon fines and typically restores normal flow. If flow remains restricted after flushing, check that the filter is fully locked and that household water pressure falls within the 30 to 120 PSI operating range.

Can I use an aftermarket filter instead of the LG LT1000P?

Aftermarket filters may physically fit the housing but certification levels and contaminant reduction performance vary widely between manufacturers. Using a filter that does not carry NSF 42 and 53 certification means contaminant reduction claims are unverified. For consistent, tested performance in your LG refrigerator, a certified replacement rated for the LT1000P housing is the more reliable choice.
