Not sure which LG water filter your refrigerator needs? Here is a complete reference to help you find the correct replacement before you buy.

Always confirm the part number printed on your existing filter or inside the filter housing before ordering. LG water filter housing designs vary across model generations and are not universally interchangeable within the LG lineup.

How do I find the right LG water filter for my refrigerator?

Check the part number printed on the existing filter currently installed in your refrigerator. That number is the most reliable confirmation of which replacement your unit requires. If the label is worn or unreadable, locate the model number inside the fresh food compartment and use it to cross-reference the correct filter code before ordering.

What happens if I order the wrong LG water filter?

An incorrectly ordered filter will not seat properly in the housing and will not deliver effective water filtration. LG water filters from different generations use different housing tolerances that prevent cross-code substitution even when the filters look similar. In some cases a mismatched filter may appear to partially fit but will 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 Replace an LG Refrigerator Water Filter?

Replace your LG refrigerator water filter 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 and should replace at that point rather than waiting. 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 Find the Right LG Water Filter

1. Locate the existing filter inside the LG refrigerator fresh food compartment
2. Check the part number printed on the label of the installed filter
3. Match that part number to the correct filter in the table above
4. Confirm your refrigerator model number against the compatibility list for that filter
5. Order the confirmed filter from the shop links below
6. Install the new filter using the twist-in tool-free design and run 2 to 3 gallons through the dispenser before drinking
7. Reset the filter indicator light per the LG refrigerator user guide for your specific model

Frequently Asked Questions

Which LG water filter do I need for my refrigerator?

Check the part number on the existing installed filter. That code is the most direct confirmation. If unreadable, find the refrigerator model number inside the fresh food compartment and match it to the compatibility list on this page.

What is the difference between the LG LT1000P and LT800P?

The LT1000P and LT800P are separate filter codes designed for different LG refrigerator model generations with distinct housing designs. The LT1000P covers newer LG models while the LT800P covers an earlier generation. They are not interchangeable.

Are all LG water filter codes interchangeable?

No. Each LG filter code has a specific housing design and compatible model range. All filters in this collection use twist-in designs but housing tolerances differ between codes making cross-code substitution unreliable and in most cases impossible.

How long do LG refrigerator water filters last?

All LG water filters in this collection are rated for 200 gallons or 6 months whichever comes first. Replace at whichever threshold arrives first for consistent filtration performance.

Can I use an aftermarket filter in my LG refrigerator?

Aftermarket filters may fit physically but certification levels and contaminant reduction performance vary widely. A filter without NSF certification means performance claims are unverified. For consistent tested performance use a certified replacement rated for your specific LG filter code.

Do LG water filters cover both the dispenser and ice maker?

On most compatible LG refrigerator models yes, a single filter housing serves both the dispenser and the ice maker. Confirm this against your specific model in the LG user guide before ordering.
