You open the refrigerator door for a cold drink and the filter light catches your eye on the display. You check the top left corner of the compartment ceiling, pull the old cartridge from its housing, and read two numbers on the casing. One reads LT700P and the other reads ADQ36006101. You need an LG LT700P replacement that fits that housing, and the two numbers point to the same cartridge. We stock the LT700P, and the label gives you everything you need to order the right part. This guide matches the two numbers, explains the two certifications on the cartridge, gives the price by pack, and shows you the swap and the flush. A new cartridge stops the chlorine taste and drops into place in a few minutes.
LT700P and ADQ36006101 are one cartridge
LT700P is the retail name, and ADQ36006101 is the LG part number printed on the casing. The two numbers lead to the same cartridge. It measures 6 7/8 inches long by 1 3/4 inches wide, and a cartridge with other dimensions fails to lock into the housing.
The cartridge holds activated carbon filtration media, and the carbon traps particles while water flows through the block. The carbon works like a sponge for the chlorine in the water line, and the block holds the sediment in its pores. If your old cartridge reads ADQ74793501 instead, you have the LT1000P, and our LG LT1000P guide covers that part.
The LT700P runs at an operating pressure of 25 to 125 psi and an operating temperature of 33 to 100 degrees Fahrenheit, and a household cold water line sits inside both ranges. The cartridge works when your home meets those two conditions, and nearly every kitchen does. Our LG Refrigerator Water Filters collection holds every LG cartridge we stock, and our Refrigerator Water Filters collection covers the other brands.
What NSF/ANSI 42 and 53 mean on this cartridge
The cartridge carries NSF/ANSI 42 and NSF/ANSI 53 certification. NSF/ANSI 42 covers taste and odor reduction, and chlorine is the main one. Water treatment plants add chlorine to disinfect the supply, and the chlorine leaves a taste and a smell behind. The carbon media reduces that chlorine taste, so your water tastes clean again.
NSF/ANSI 53 covers health related contaminants such as cysts and lead, and the cartridge reduces the ones its own listing covers. The LT700P reduces rust, dirt, sediment, limescale, sand, silt, algae, cysts, turbidity and other common particulates. The carbon block captures those materials as the water passes through, and the certification is the health fact that matters on this cartridge. A filter reduces what its listing covers, and it cures nothing. The part exists to improve the water at your dispenser and in your ice bin.
Six months or 200 gallons, whichever comes first
The cartridge runs on two clocks. LG rates the filter life at 6 months or 200 gallons, and you replace it when the first limit arrives. Our replacement guide explains that the "Replace Filter" light triggers at about the six month mark and counts no gallons. The light comes on whether you drank one glass or a hundred.
Your household sets the gallon clock. That same guide notes that a family of four or five running the ice maker through a warm summer can move 200 gallons in three or four months, and that a refrigerator cartridge is a carbon block that adsorbs chlorine and sediment until the media reaches capacity. Replace the cartridge every 6 months to keep the media working, and sooner when the gallon clock runs out first. Count where the filtered water goes in your kitchen. The dispenser, the ice maker, the coffee pot and the refilled bottles all draw through the same cartridge, and a busy kitchen empties 200 gallons faster than the calendar suggests.
Carbon media also ages on the shelf inside the refrigerator, so a cartridge in a lightly used second refrigerator still gets replaced at the six month mark. The refrigerator shows you when a cartridge is due. You notice a returning chlorine taste in the glass, a slower dispenser flow, slower ice, cloudy cubes, or a light you dismissed weeks ago. None of these signs is an emergency. The carbon block is full, and a fresh cartridge restores the flow.
Price by pack
We offer the Replacement LG LT700P Refrigerator Water Filter in four pack sizes.
| Pack size | Total price | Price per cartridge |
|---|---|---|
| 1 Pack | $24.99 | $24.99 |
| 2 Pack | $49.98 | $24.99 |
| 3 Pack | $77.99 | $26.00 |
| 6 Pack | $146.99 | $24.50 |
The 1 Pack costs $24.99 and the 2 Pack costs $49.98, which keeps the price at $24.99 per cartridge. The 3 Pack costs $77.99, or $26.00 per cartridge. The 6 Pack costs $146.99 and drops the price to $24.50 per cartridge. Some households want one cartridge for the swap in front of them, and others want six on the shelf for three years of changes. We ship whichever pack you choose, and the spare cartridges wait in the pantry in their sealed wrap until the light comes on again.
How to swap the LT700P
Replacing the cartridge takes a few minutes and no tools. You use your hands to remove the old part and seat the new one, and the refrigerator manual gives the exact steps for your model. Keep a towel under the compartment, because a few drops fall when the old cartridge comes out.
- Open the filter compartment door on the ceiling of the refrigerator.
- Turn the old cartridge counterclockwise and pull it out of the housing.
- Remove the protective cap from the new cartridge.
- Insert the new cartridge and turn it clockwise until it seats.
- Close the compartment door.
- Flush about 4 gallons of water through the dispenser.
- Hold the filter reset button per the refrigerator manual to clear the light.
The last two steps matter most for good water. Our troubleshooting guide explains that you flush about 4 gallons through the dispenser before you judge the new cartridge, and that the sputtering and gray water in that flush are trapped air and loose carbon fines. The water clears once you push enough volume through the line, and four gallons is about ten large glasses. The air needs an escape route and the fines need a rinse, and the flush handles both at once. Then hold the reset button, and the refrigerator starts a fresh six month count.
Set the reorder on Subscribe and Save
Our Subscribe and Save program takes the six month clock off your calendar. The program gives you a standing 5 percent discount on every recurring shipment, and you choose an interval of three months, six months or a year. The six month interval matches the LG rating, and a busy kitchen can set three months instead. On the 1 Pack, 5 percent off $24.99 is $23.74. You lock in the lower price and remove a chore from your calendar. We ship the package on your schedule, and you open the box and swap the cartridge. You can pause a shipment, shorten the interval for a busy kitchen, or cancel from your account.
Frequently Asked Questions
Is ADQ36006101 the same as LG LT700P?
Yes. The two numbers refer to the same cartridge. LT700P is the retail name on the packaging, and ADQ36006101 is the LG part number on the casing. Order by either number, and the cartridge drops into the ceiling compartment. The dimensions and the media match, because it is one part.
How long does the LT700P last?
LG rates the cartridge for 6 months or 200 gallons, and you replace it at the first of those two limits. A busy household with a working ice maker can reach 200 gallons in three or four months. A quiet household reaches the 6 month limit first. A full carbon block stops capturing sediment.
Is the LT700P NSF certified?
Yes. The cartridge carries NSF/ANSI 42 and 53 certification. NSF/ANSI 42 covers the reduction of taste and odor, chlorine among them. NSF/ANSI 53 covers the reduction of health related contaminants such as cysts and lead. The cartridge reduces the items its listing covers.
Why does the water sputter after I change the filter?
A new cartridge holds trapped air and loose carbon fines. Water hits the dry carbon for the first time and pushes the air out through the dispenser, which causes the sputter, and the water carries some carbon fines with it, which turns the first glasses gray. Flushing about 4 gallons through the dispenser clears both.
