LG LT700P Refrigerator Water Filter

LG LT700P Water Filter Replacement

The LG LT700P refrigerator water filter — the cartridge behind LG part number ADQ36006101 — is the activated carbon filter for the wide generation of LG refrigerators built around that specification. Rated for 300 gallons, it quietly takes the chlorine taste and odour out of your refrigerator’s water, traps the sediment that turns ice cloudy, and keeps both tasting clean for roughly six months of everyday family use before it asks to be changed. The change itself could hardly be simpler: the cartridge twists out of its compartment inside the fridge and the new one twists in by hand, with no tools and no plumber. If your filter light has come on, if drinks have started to taste of the treatment plant again, or if your ice has picked up smells from the freezer, the odds are strong that the cartridge in the housing is simply at the end of its life. Replacing it with the correct LT700P — ordered by the ADQ36006101 number on the label of the one you already have — is the whole fix.

Why Choose the LG LT700P Water Filter

The LT700P’s first virtue is that it is the cartridge your refrigerator was actually designed around. Fit is not a detail in a water filter; it is the whole mechanism. The cartridge must seal against the housing so that every drop of dispenser water is forced through the carbon media — a near-enough cartridge can leave a bypass gap, and bypassed water is unfiltered water, however good the carbon inside the cartridge might be. The second virtue is capacity: at 300 gallons, the LT700P carries half as much again as the 200-gallon cartridges used in some other LG generations, which suits households that use the dispenser heavily. Inside, its activated carbon offers a huge internal surface area to the water flowing through, and chlorine and taste-and-odour compounds are adsorbed onto that surface and held. Sediment — the rust, sand and scale fines that water picks up on its way to your house — is strained out too, which is why ice cubes freeze clearer and stop carrying other flavours. Choose the LT700P by its number, and you are choosing the sealed fit, the longer capacity and the clean taste your fridge was built to deliver.

Compatible Refrigerators

The LT700P fits LG refrigerators whose filter specification calls for the LT700P / ADQ36006101 cartridge — a long-running generation of LG models. The two names describe the same single cartridge: LT700P is the name it is sold under, ADQ36006101 is the LG part number, and either one on your old cartridge or in your manual identifies this filter.

LG Refrigerators That Take the ADQ36006101 Cartridge

LG used this cartridge across a broad run of its refrigerators, in French-door and side-by-side layouts alike. Models in this generation carry the filter inside the fresh-food compartment, in a housing the cartridge twists into. Because the generation is wide, the model badge alone cannot tell you whether a given fridge is an LT700P model — fridges that look alike from the front can take different cartridges from different years. That is exactly why LG prints the part number on the cartridge itself.

If You Are Replacing an Older LG Cartridge

Owners of older LG refrigerators are the people most often caught out by lookalike filters: LG has run several cartridge designs over the years (the LT600P before this generation, the LT800P and LT1000P in others), and while they share a family resemblance, none of them interchange. If your old cartridge’s label carries a different number, order that number instead — the correct filter is always the one whose part number matches the cartridge that came out.

Check the Cartridge You Already Have

The definitive test takes ten seconds: twist the old cartridge out and read the label. LT700P or ADQ36006101 means you are in the right place. Your refrigerator manual’s filter specification will confirm it. Buying by the cartridge number rather than by the fridge’s name, age or appearance is the one habit that guarantees a sealed fit and filtered water every time.

How the LT700P Cleans Your Water

The working part of the LT700P is its activated carbon. “Activated” means the carbon has been processed to be full of microscopic pores, so even the modest volume inside a fridge cartridge contains an enormous surface area. As water is pushed through, two things happen: chlorine and the organic compounds that give tap water its treated taste and smell are adsorbed — bonded onto the carbon’s surface and removed from the water — and particulate sediment is physically strained out. The difference is immediately obvious in a glass: no chemical tang, no odour, and ice that freezes clear instead of white and cloudy. It is worth being clear about the boundaries, because they define honest expectations: this is a taste, odour and clarity filter working on tap water that is already treated and safe. It does not soften hard water, it does not remove dissolved minerals, and it does not sterilise. What it does, it does thoroughly and for its full 300-gallon rating — it makes the water your fridge serves taste the way plain water should.

Fresh Water for Everyday Use

Think about how much of your household’s water actually arrives through the refrigerator door. The kettle for the morning tea and coffee, the bottles filled for work, school and the gym, the jug that anchors the dinner table, the ice that goes into everything cold — nearly all of it passes through this one cartridge. With a fresh LT700P in place, coffee tastes of coffee rather than of chlorine, cordials and squash taste of fruit, and cooking water starts neutral for rice, pasta and soups. Ice is the silent beneficiary: made from filtered water, it freezes clearer, melts cleaner, and stops absorbing and returning the odours of whatever else lives in the freezer. Households rarely notice the filter while it is working; they notice it in the fortnight after it gives up, when the dispenser falls out of favour and the bottled water comes back. Six-monthly changes keep that from ever happening.

Easy to Replace

The LT700P changes by hand in about a minute:

1. Locate the filter compartment inside the fridge — on models of this generation the cartridge sits inside the fresh-food compartment and twists out of its housing.
2. Put a small towel beneath it; a little water trapped in the old cartridge will usually drip as it comes out.
3. Twist the old cartridge to release it and pull it out of the compartment.
4. Read the label before discarding it — LT700P / ADQ36006101 is the number to reorder, and worth a note on the fridge door list.
5. Seat the new LT700P in the housing and twist it until it locks firmly. A cartridge that is not fully home is the classic cause of a weak dispenser stream and slow drips.
6. Flush the new filter: run 2 to 2.5 gallons through the dispenser and throw that water away. New carbon releases trapped air and fine particles at first, so the water may look cloudy or greyish briefly; flushing clears it.
7. Discard the first batch of ice, which is made from the flush water.
8. Reset the filter indicator if your model has one: on most LG models, press and hold the Filter (or Reset) button on the dispenser panel for about three seconds until the light goes out. Your manual names the exact button.

Full flow and clean taste should be back immediately.

Keeping Your LT700P on Schedule

The rating is 300 gallons, which the average household reaches in about six months — so the rule is six months or 300 gallons, whichever lands first. The subtlety with carbon filters is that exhaustion is invisible from the tap: the water keeps coming, it simply stops being cleaned on its way through. Your warnings are sensory ones — the dispenser stream thinning, cubes coming out smaller, hollower and cloudier, and that treated taste sidling back into drinks. The indicator light, where fitted, is the backstop, not the alarm. Keep the rhythm simple: new cartridge in first, then reset the light, then write the date somewhere you will see it in six months. And do not be tempted to rinse an old cartridge and put it back — adsorption is a chemical capacity that gets used up, not a coating that can be washed off, so a rinsed LT700P filters no better the second time than it did the day it came out.

Pack Sizes and Value

Every pack contains the same LT700P cartridge — all that changes is how many changes you have covered in advance. Every order from Discounted Filter Store ships free anywhere in the US, on any amount:

• 1-Pack — $41.99: one cartridge, 300 gallons, about 6 months of cover.
• 2-Pack — $84.99: two cartridges, 600 gallons, about a full year of cover.
• 3-Pack — $127.99: three cartridges, 900 gallons, about 18 months of cover.
• 4-Pack — $170.99: four cartridges, 1,200 gallons, about two full years of cover.

Because this filter lives on a twice-a-year rhythm, the 2-Pack is the standard annual answer and the 4-Pack settles two years at once — one order, free delivery, and the next change is already in the cupboard when the light comes on. There is no subscription to remember or cancel, and because shipping is free even on a single cartridge, buying one at a time remains a perfectly sensible option too.

A Reliable Choice for Clean Water

If your refrigerator’s cartridge reads LT700P or ADQ36006101, there is exactly one correct replacement, and this is it: the sealed fit your housing was built for, 300 gallons of activated carbon filtration for chlorine taste, odour and sediment, and a one-minute, tool-free change. Match the label, twist it in, and forget about it for another six months.

FAQ’s

Here is the frequently asked questions about this product

What is the LT700P?
The LT700P is an LG refrigerator water filter cartridge with activated carbon media. It is rated for 300 gallons — about six months of typical use — and reduces chlorine taste and odour while trapping sediment. Its LG part number is ADQ36006101.

Is the LT700P the same as ADQ36006101?
Yes — they are two names for the same cartridge. ADQ36006101 is the part number LG assigns it; LT700P is the name it is sold under. Either number on your old filter or in your manual means this is your replacement.

How long does the LT700P last?
Around six months, or 300 gallons, whichever comes first. Heavy dispenser use can shorten that a little; slow flow, poorer ice and returning taste are the signs it is due.

Will the LT700P fit my LG refrigerator?
It fits the LG refrigerators whose filter specification is the LT700P / ADQ36006101 cartridge — a wide generation of models. The certain check is the label on your existing cartridge or the specification in your manual. Do not fit it in place of an LT600P, LT800P or LT1000P; those are different cartridges for different housings.

How much water should I flush after fitting a new LT700P?
Run 2 to 2.5 gallons through the dispenser and discard it, and throw away the first batch of ice. This purges air and loose carbon fines from the new cartridge; brief cloudiness during the flush is normal.

How do I reset the filter light?
After fitting the new cartridge, press and hold the Filter or Reset button on the dispenser panel for about three seconds, on most LG models, until the indicator goes out. If your model has no indicator, simply note the change date instead.
