LG Refrigerator Water Filters and Air Filters

LG builds a handful of filters across its refrigerator range, and the right one comes down to your model and its age. Fine Filters Store stocks the LG water filters and fresh air filters that fit, matched by part number, with free US shipping and a team on hand to confirm your fit before you buy.

Match your refrigerator to the line below, then order the part it names.

• LG French door fridge from 2017 onward uses the LT1000P water filter, also sold as ADQ74793501.
• Older LG French door or side-by-side takes the LT700P, also sold as ADQ36006101.
• Older LG or LG-built Kenmore often runs the LT500P or the LT800P.
• A small vent filter inside the cabinet is the LT120F fresh air filter that clears odors.
• Fresh water and fresh air together means pairing the LT1000P with the LT120F.

Which LG Water Filter Does My Refrigerator Use?

The safest way to identify your LG refrigerator water filter is to read the part number off the cartridge already in the fridge or check the manual. Most current French door models use the LT1000P, which carries NSF and ANSI certification and reduces more than twenty contaminants, including chlorine taste, some pharmaceuticals, and trace metals. Refrigerators built before that generation usually take the LT700P, while a range of older LG units and LG-made Kenmore fridges use the LT500P or LT800P. The cartridge shape and the compartment it clicks into stay specific to each part, so the number matters more than the model name.

What Is the Difference Between the LT1000P and the LT700P?

These two cover most LG shoppers, and picking between them comes down to your refrigerator, not a performance gap you get to choose. Both reduce chlorine taste and odor and both run for about six months. The LT1000P is the newer design certified against a wider list of contaminants, and it fits the later French door models. The LT700P is the earlier part for the fridges built before that change. Use the one your refrigerator was designed around.

Does My LG Fridge Need an Air Filter Too?

Many LG refrigerators hold a second filter you might have missed. The LT120F fresh air filter clips into a small vent inside the cabinet and uses activated carbon to absorb the odors that jump between foods, so onions and leftovers stop tainting your butter and berries. It works alongside the water filter rather than replacing it, and LG sells the two together for owners who want to handle both at once. If your model has that vent, keeping the air filter fresh is the quiet difference between a fridge that smells clean and one that does not.

Are the LT1000P, LT1000PC, and LT1000PCS the Same Filter?

Yes, and this trips up a lot of buyers. The LT1000P, LT1000PC, and LT1000PCS are the same water filter, and the extra letters point to packaging and version updates rather than a different fit or a different level of filtration. Whichever suffix you find on your old cartridge, any of these versions drops into the same slot and performs the same way. Order by the LT1000P name and you are covered.

How Often Should I Replace an LG Filter?

LG water filters run for about six months or 200 gallons, whichever lands first, and the LT120F air filter follows a similar six month rhythm. A few signals tell you the moment has arrived before the calendar does.

• Water dispenses more slowly than it used to.
• Ice tastes flat or picks up a chlorine note again.
• The filter indicator on the door turns from clear to red.
• The fridge holds odors even after you clean it, which points to the air filter.

Homes with hard water or heavy daily use reach these points sooner, so read the water and the airflow rather than waiting on the date alone.

How Do I Install an LG Refrigerator Filter?

Both filters swap in without tools. For the water filter, turn the old cartridge counter-clockwise, pull it out, and push the new LT1000P or LT700P in until it locks with a quarter turn. Run about two and a half gallons through the dispenser to flush trapped air and loose carbon, then reset the filter indicator so it counts from the fresh cartridge. For the LT120F, open the small air filter cover inside the cabinet, lift out the old pad, click the new one into the frame, and reset its own timer if your model tracks it. The pair takes only a few minutes together.
