LT1000P and LT1000PC are two labels you’ll see for the same LG refrigerator filter family, and we sell them as one product. Our listing groups both names with LG part number ADQ747935. If your fridge calls for one, the quickest way to be certain the other fits is to check the part number on your current cartridge or the replacement filter line in your owner’s manual.

The confusion is understandable. One listing says LT1000P, another says LT1000PC, and a two-pack might say LT1000PCS. Here’s how to read those labels and confirm your fit in a couple of minutes.

What the Labels Tell You

LG sells this filter under a few closely related names. Ignore the suffix for a moment and focus on the part number underneath, because that’s what identifies the cartridge.

• LT1000P: the model name LG uses on its own product page for this filter.
• LT1000PC: a name that appears on many retail listings for this same filter family. Our product listing covers both LT1000P and LT1000PC.
• LT1000PCS: the name LG has used for a two-pack of this filter, which LG now lists as discontinued.
• ADQ747935: the core LG part number. You’ll often see it with extra digits, such as ADQ74793501 or ADQ74793502.

LG’s own page for the LT1000P lists several part numbers under that one model, including ADQ74793501. So a cartridge or box can carry more than one number and still be the same filter.

What LG Says About Performance

LG rates the LT1000P for 6 months or 200 gallons, whichever comes first, and lists it as certified to NSF/ANSI 42, 53 and 401. LG also describes it as a simple twist-in filter that needs no tools.

If you’re curious what those three standards actually test for, our guide to NSF 42, 53 and 401 explained breaks each one down in plain terms. When you compare any filter, read the certifications listed for that exact product rather than assuming they carry over from another box.

How to Confirm Which Filter Your Fridge Takes

LG doesn’t spell out the difference between every suffix in one place, so the safest move is to confirm your fit directly. You have three good options.

Check the Cartridge You’re Replacing

Twist out your current filter and read its label. If you see ADQ747935, with or without extra digits after it, you’re in the LT1000P family. Snap a photo of the label before you throw the old filter away so you have it for next time.

Look at Your Owner’s Manual

Find the water filter or replacement cartridge section in your manual. It names the filter your refrigerator is designed for. If you no longer have the paper copy, you can download it from LG’s support site using your fridge’s model number.

Match Your Refrigerator Model Number

The model sticker is usually inside the fresh food compartment, on a side wall or near the ceiling. Our LT1000P / LT1000PC refrigerator water filter listing names a few LG models it replaces, including the LMXS28626S, LMXC23796S and LFXS26973D, along with LG part numbers ADQ747935, ADQ74793501 and ADQ74793502 and the Kenmore 9980. If your model or part number is on that list, you’ve found your filter, with lower prices than the big-name stores and free shipping on every order.

If your model isn’t listed, that doesn’t mean it won’t fit. It means it’s worth a quick check with your manual or with our team before you order.

Why Looks Alone Can Mislead You

Many LG filters are white cylinders with a twist-in end, and they can look almost identical in photos. LG makes several different filters, such as the LT700P and LT800P, and those are separate cartridges built for different housings.

A filter that goes in but doesn’t lock properly can leak inside the fresh food section or slow your water to a trickle. Matching by part number takes the guesswork out of it.

Fridge series names cause the same trouble. Two LG refrigerators from the same year and style can take different filters, so always go by the model number on the sticker, not the product line.

Getting the Best Value on Your Replacement

Once the fit is settled, compare price per filter, not just the sticker price. Divide the pack price by the number of cartridges to see what each one really costs you.

Since LG rates this filter for about six months, buying more than one at a time means your next replacement is ready when the indicator comes on. It also helps you avoid running a filter well past its rating.

Swapping In Your New LT1000P Filter

On most LG models that use this filter, the housing is in the upper part of the fresh food compartment. The swap usually goes like this:

1. Turn the old filter counterclockwise and pull it out. Keep a towel handy for a few drips.
2. Remove the protective cap from the new cartridge.
3. Push the new filter into the housing and turn it clockwise until it stops.
4. Run water through the dispenser to clear air and loose carbon, following the flush amount in your manual.
5. Reset the filter indicator using the steps for your model.

Our full LG refrigerator water filter replacement guide covers each step in more detail, including what to do if the filter feels stuck.

Frequently Asked Questions

Can I use an LT1000PC if my manual says LT1000P?

Both names are used for the same LG filter family, and our listing covers both. To be certain, check that the part number on your old cartridge starts with ADQ747935, or send us your model number and we’ll confirm it.

Is LT1000PCS the same filter?

LG has used LT1000PCS for a two-pack with the same 6 month, 200 gallon rating as the LT1000P. LG now shows that two-pack as discontinued.

Will the LT1000P fit my LG refrigerator?

It fits the LG models that call for it in the manual or that show ADQ747935 on the current cartridge. Not every LG fridge takes this filter, so check before ordering.

How often should I replace this filter?

LG rates it for 6 months or 200 gallons, whichever comes first. Heavy water and ice use can get you to 200 gallons sooner.
