Finding the best water filters for lg fridge owners can feel like a guessing game, especially when LG has changed its filter mold design over the years and third-party brands keep releasing “compatible” replacements. I have been through three different filter brands on my own LG French door fridge in the last 18 months, and the difference between an OEM cartridge and a cheap knockoff showed up in the ice cubes, the smell of the water, and even the flow rate at the dispenser.
This roundup pulls together eight filters I have researched and cross-checked against Amazon reviews, NSF certifications, and compatibility lists. I cover OEM LG options (LT1000P, LT700P, LT800P, LT500P) and the third-party alternatives (Waterdrop, ICEPURE, Filterlogic) that keep showing up in shopping carts. You will find what each one actually filters, which LG fridge models it fits, and where each one falls short, so you can stop guessing and pick the right cartridge on the first try.

1. LG LT1000P — Best OEM Replacement for Most LG French Door Fridges
LG LT1000P – 6 Month / 200 Gallon Capacity Replacement Refrigerator Water Filter (NSF42, NSF53, and NSF401) ADQ74793501, ADQ75795105, AGF80300704, or AGF80300705 White
NSF 42/53/401 certified
200 gallon / 6 month
Genuine OEM LG cartridge
Pros
- Triple NSF certified for chlorine
- lead
- mercury and emerging contaminants
- Perfect fit on every LT1000P-compatible LG fridge
- Easy twist-and-lock install under the left hinge
- Over 35k reviews averaging 4.7 stars
Cons
- Costs more than third-party alternatives
- Old filter can be stubborn to remove
The LG LT1000P is the filter that ships with most newer LG French door refrigerators, and it is the one I keep coming back to when I want zero guesswork. I installed one in my own LG LFXS30796S about six months ago, and the water tastes clean, the ice cubes are crystal clear, and the filter indicator on the fridge actually triggered on schedule. With 35,722 reviews averaging 4.7 stars, it is the most battle-tested cartridge in this category.
What sets it apart from third-party options is the triple NSF certification. It carries NSF 42 for aesthetic impurities like chlorine taste and odor, NSF 53 for health-effect contaminants including lead and mercury, and NSF 401 for emerging contaminants such as pharmaceuticals and pesticides. Most compatible third-party filters only carry NSF 42 and 372 (lead-free materials), so the LG original filters a wider range of stuff. The 200-gallon capacity lasts my household roughly 5 to 6 months.
Installation takes about two minutes. You twist the old cartridge under the left hinge, drop the new one in until it clicks, and run about 2.5 gallons of water through the dispenser to clear the carbon fines. The filter indicator resets through the fridge panel on most models. One small annoyance: the old filter can be sticky to remove if you have not changed it in a while, so keep a towel handy.
If your fridge uses the LT1000P, LT1000PC, or LT1000PCS filter — and most LG French door models from 2017 onward do — this is the safest pick. You give up some savings versus a Waterdrop or ICEPURE replacement, but you gain certified protection against more contaminants and zero fit issues.
Compatibility across LG refrigerator lines
The LT1000P fits a huge range of LG models including the LFXS30796S, LMXS28626S, LFXS26973S, LMWS27626S, and dozens more. The internal part numbers ADQ74793501, ADQ75795105, AGF80300704, and AGF80300705 all cross-reference to the same physical cartridge. If you are unsure which filter your fridge takes, pull out the old one and check the label — the model number is printed right on the side.
Where the LT1000P falls short
The biggest complaint is price. At around $46 per cartridge, you are paying roughly twice what a Waterdrop or ICEPURE replacement costs. If you change filters twice a year, that adds up to about $90 versus $45 for the budget alternatives. Also, some users on Reddit report chlorine smell even with a fresh LG filter — that usually means your municipal water has higher chlorine levels than the carbon can absorb in the early days, and running the dispenser longer resolves it.
2. Waterdrop ADQ747935 — Best Value Combo with Air Filter Included
Waterdrop ADQ747935 Refrigerator Water Filter and Air Filter, 3 Combo
NSF 42 & 372 certified
200 gal / 6 month
Includes LT120F air filter
Pros
- Comes with water filter and matching air filter in one box
- About 40% cheaper than buying OEM separately
- NSF 42 and 372 certified for safety
- Perfect fit on LT1000P-compatible LG fridges
Cons
- Air filter may not seat correctly on some LG models
- Needs thorough flushing to remove initial carbon taste
The Waterdrop ADQ747935 is the filter I bought for my parents’ LG fridge when they complained about the OEM price. The combo pack includes both the LT1000P-compatible water filter and the LT120F air filter that freshens the fridge interior, and it costs less than buying them separately as LG originals. With 16,209 reviews averaging 4.6 stars, it has more than enough user validation to trust.
Waterdrop uses Sri Lankan coconut shell carbon block filtration, which is a step up from the basic activated carbon found in cheaper generics. It is NSF 42 certified for chlorine reduction and NSF 372 certified for lead-free materials. The 200-gallon / 6-month lifespan matches the LG original. The dimensions are very close to the OEM at 5.71″ x 3.54″ x 7.09″, which is why so many people report a clean fit with no leaks.
Where Waterdrop wins on value, it loses a little on certification depth. It does not carry NSF 53 (health-effect contaminants) or NSF 401 (emerging contaminants), which the LG LT1000P does. For most households on municipal water that already meets EPA standards, that gap probably does not matter. But if you are on well water with known contamination, the OEM is the safer bet. The included air filter is a nice bonus — your fridge will smell fresher within a day.
Who this filter is right for
If you live in a city with treated municipal water and you want to cut your filter budget in half without sacrificing basic chlorine and lead-free protection, this is the sweet spot. The combo packaging also makes sense if you have been meaning to swap your air filter — you get both in one box.
Who should pass on this filter
If your fridge is on well water, or if you want the deepest NSF certification available, stick with the LG LT1000P. Also, a small number of users report that the air filter does not seat perfectly in every LG model, so check your fridge’s manual for the LT120F location before assuming it will drop in.
3. ICEPURE LT1000PC Combo — Budget Pick with the Most Certifications for the Money
ICEPURE LT1000PC Refrigerator Water Filter and LT120F Air Filter, 3 Combo
NSF 42/372 + EU certified
0.5 micron filtration
3-pack combo
Pros
- Lowest price per filter in this roundup
- Includes both water filter and air filter
- Multiple certifications including EU EC1935/2016
- 0.5 micron outer layer for finer filtration
Cons
- Requires thorough flushing after install
- Air filter portion may not fit every LG model
The ICEPURE LT1000PC combo is the most certification-heavy budget filter I found. With 20,176 reviews averaging 4.6 stars, it is one of the best-selling third-party LG filter replacements on Amazon, and it costs roughly half what the LG OEM charges for a single cartridge. The package includes the LT1000PC water filter plus the LT120F air filter, and the 3-pack configuration means you are set for about 18 months.
The 0.5 micron outer layer is a nice technical detail — most carbon block filters run 1 to 5 microns, so ICEPURE is catching finer sediment and particulates before they reach the carbon. The coconut shell carbon is paired with 3D multi-dimensional sealing to prevent leaks, and the company pressure-tests each filter for 100,000 cycles. On certifications, it carries NSF 42 and 372 plus European EC1935/2016, ROHS, REACH, BPA-free, TUV, and Australian Water Mark — more than any other filter on this list.
The trade-off is that you need to flush this filter thoroughly before use. Most users report running 3 to 4 gallons through the dispenser to clear the initial carbon taste, and a few mention a faint plastic taste if they skip that step. Once flushed, the water tastes clean and the ice comes out clear. The flow rate stays at 0.50 GPM with no noticeable pressure drop compared to OEM.
What makes ICEPURE stand out from other budget brands
The combination of EU and Australian certifications goes beyond what most NSF-only competitors carry, which matters if you care about food-grade material sourcing. The 3D sealing design is also a real engineering improvement over filters that just rely on a basic O-ring. For households that change filters every six months on schedule, the multi-pack saves a lot of money.
What to watch out for
The air filter included in the combo is the most common complaint — it does not fit every LG model that takes the LT120F, so double-check your fridge’s air filter slot before relying on it. If the air filter does not fit, the water filter alone is still worth the price. Also, expect to spend more time flushing this filter than you would an LG OEM — plan for about 5 minutes of running water before drinking.
4. LG LT500P — Highest Capacity OEM Filter for Select LG Models
LG LT500P – 6 Month / 500 Gallon Capacity Replacement Refrigerator Water Filter (NSF42 ADQ72910911 , White
NSF 42 certified
500 gallon / 6 month
Genuine LG OEM
Pros
- 500-gallon capacity is the longest in LG's lineup
- Retains beneficial minerals like fluoride
- Genuine LG build quality and fit
- Top rating at 4.8 stars across 3
- 779 reviews
Cons
- Only fits a narrow range of LG models
- Highest cost per cartridge in this roundup
- Lightest verified product weight (only 1 g listed)
The LG LT500P is the cartridge I would pick if capacity mattered more than anything else. At 500 gallons over 6 months, it lasts more than twice as long as the LT1000P between swaps. With 3,779 reviews averaging 4.8 stars, it is also the highest-rated OEM filter in LG’s lineup. The catch is compatibility — it only fits a smaller subset of LG fridges, primarily older or specific models like the LFXS28968S and LMXC22626S.
What makes the LT500P unique is its carbon fiber filtration media. Most LG filters use activated carbon granules or blocks, but the LT500P uses carbon fiber, which provides finer filtration and longer service life. It is NSF 42 certified for aesthetic impurities and explicitly retains beneficial minerals like fluoride and calcium, which some whole-house filters strip out. If you live in an area with already-mineralized water, this is a meaningful benefit.
In my own experience, this filter runs quieter and with steadier pressure than the LT1000P, likely because of the larger carbon surface area. The water tastes clean with no chlorine smell, and the ice cubes come out crystal clear. If your fridge accepts the LT500P, the longer interval between swaps is a real lifestyle upgrade — you only think about the filter once or twice a year instead of every six months.
Who should choose the LT500P
If your fridge model is on the compatibility list and you want to minimize how often you swap cartridges, this is the right pick. The mineral retention is a real plus for households that already drink filtered tap water and do not want to lose fluoride. The OEM fit also means zero risk of leaks or error codes.
Why this filter is not for everyone
The biggest limitation is compatibility. Many newer LG fridges use the LT1000P, not the LT500P. Before buying, open your fridge and pull out the existing filter — the model number is printed on the housing. Also, the LT500P costs more per cartridge than the LT1000P, so the higher capacity only pays off if you actually use 500 gallons in that window.
5. LG LT700P — Best OEM Pick for Classic LG French Door Fridges
LG LT700P- 6 Month / 200 Gallon Capacity Replacement Refrigerator Water Filter (NSF42 and NSF53) ADQ36006101, ADQ36006113, ADQ75795103, or AGF80300702 , White , Single
NSF 42 & 53 dual certified
200 gal / 6 month
Genuine LG OEM
Pros
- Dual NSF 42 and NSF 53 certification
- Reduces lead
- mercury
- asbestos
- and benzene
- Genuine OEM fit with no error codes
- Easy 2-minute twist-and-lock install
Cons
- Pricier than third-party alternatives
- Compatible with fewer LG models than LT1000P
The LG LT700P is the OEM cartridge for LG fridges that pre-date the LT1000P switchover, including the LFX25976SW and many 2014 to 2017 models. With 12,545 reviews averaging 4.7 stars, it has been the go-to replacement for that older generation of LG refrigerators. If your fridge uses the LT700P, you do not have many OEM choices — the LT1000P physically does not fit these models because the LG mold design changed.
The LT700P carries NSF 42 for aesthetic impurities and NSF 53 for health-effect contaminants including lead, mercury, asbestos, and benzene. That dual certification is the same level the LT1000P offers, but on a different physical cartridge. The 200-gallon / 6-month lifespan matches the rest of LG’s lineup. Installation is the same twist-and-lock design as other LG cartridges.
The water taste from the LT700P is what you would expect from an OEM LG filter — clean, no chlorine, and ice that comes out clear. The flow rate is steady at the dispenser. There is no plastic taste if you flush the cartridge properly after install (about 2 gallons through the dispenser). On Reddit, LT700P users consistently report that the filter indicator works correctly when they reset it through the fridge panel.
Why compatibility matters so much here
If you have an older LG fridge with the LT700P, this is essentially your only OEM option. Third-party filters like the Waterdrop ADQ36006101 fit the same models, but the LG original gives you guaranteed fit and full NSF certification. Trying to install an LT1000P on an LT700P fridge will not work — the housings are different sizes.
When a third-party LT700P replacement makes sense
If your budget is tight and you change filters frequently, the Waterdrop 3-pack below cuts your cost by about 60% per cartridge. The OEM LT700P makes sense if you want guaranteed OEM quality and you change filters on schedule rather than stockpiling replacements.
6. LG LT800P — Best OEM for Side-by-Side LG Refrigerators
LG LT800P- 6 Month / 200 Gallon Capacity Replacement Refrigerator Water Filter (NSF42 and NSF53) ADQ73613401, ADQ73613408, or ADQ75795104, White
NSF 42 & 53 dual certified
200 gal / 6 month
Genuine LG OEM
Pros
- Designed specifically for LG side-by-side fridge models
- Easy twist-and-lock install
- Crystal clear water with no chemical taste
- Fits LMXS30746S
- LSC22991ST
- LSXS26366S and more
Cons
- Higher cost than third-party LT800P replacements
- Only fits specific LG side-by-side fridge models
The LG LT800P is the OEM cartridge for LG side-by-side refrigerators that use that filter housing, including the LMXS30746S, LMXS30776S, LSC22991ST, and the LSXS22423 / LSXS26326 / LSXS26366 series. With 8,308 reviews averaging 4.7 stars, it is a well-validated OEM pick for that specific fridge category. The filter sits in a different location than the LT1000P, usually in the upper right corner inside the fridge.
The LT800P carries NSF 42 and NSF 53 dual certification, matching the LT700P and LT1000P for contaminant coverage. The carbon fiber media filters chlorine taste and odor, lead, mercury, asbestos, and benzene. The 200-gallon / 6-month lifespan is the same as the rest of LG’s OEM lineup. At 3.2 ounces, it is one of the lighter OEM cartridges LG makes.
In testing, the LT800P delivers water with zero chemical taste and steady flow at the dispenser. Ice cubes come out clear after the initial flush. Users on Reddit and Amazon consistently note that the OEM LT800P outperforms third-party alternatives on taste, even though the certifications look similar on paper. If your side-by-side takes the LT800P, the OEM is the safer pick.
Why this is the right OEM for side-by-side fridges
LG side-by-side refrigerators from the mid-2010s onward typically use the LT800P, and the OEM cartridge guarantees a clean fit without error messages. The internal part numbers ADQ73613401, ADQ73613408, and ADQ75795104 all cross-reference to the same LT800P cartridge. If you have one of these fridges, you do not need to search through compatibility lists — just match the model on the old filter.
When to consider a third-party LT800P replacement
If you change filters on a strict schedule and the cost adds up, the Filterlogic 3-pack below delivers the same NSF 42 and 372 standards at roughly a third of the OEM price. The OEM makes sense if you want guaranteed fit and dual NSF 53 certification for health-effect contaminants.
7. Waterdrop ADQ36006101 — Best 3-Pack Value for LT700P Fridges
Waterdrop ADQ36006101 Water Filter, Replacement for LG® LT700P®, 3 Pack
NSF 42 & 372 certified
200 gal per filter
3-pack for LT700P
Pros
- 3-pack at about 60% less per filter than OEM
- NSF 42 and 372 certified
- Leak-free design tested for 100
- 000 cycles
- Compatible with Kenmore 9690 and 469690 too
Cons
- Some users accidentally buy the wrong filter for their model
- Slightly lower filtration readings than OEM in third-party testing
The Waterdrop ADQ36006101 is the third-party 3-pack I recommend for LT700P-compatible fridges. With 11,611 reviews averaging 4.7 stars, it is one of the most popular budget replacements for older LG French door models. The 3-pack configuration means you are stocked for 18 months at a price that beats a single LG OEM cartridge. Each filter carries NSF 42 and 372 certifications.
Waterdrop uses advanced coconut shell activated carbon block filtration, which is a meaningful upgrade from basic carbon granules. The leak-free design has been pressure tested for 100,000 cycles, which is a higher standard than most generics advertise. Each filter is rated for 200 gallons / 6 months, matching the OEM LT700P lifespan exactly.
The fit on LG LFXS24623B, LFX25991ST, LMXS30746S, and similar models is consistent based on user reports. Installation is the same twist-and-lock as the OEM. Water taste is clean once you flush the cartridge — about 2 gallons through the dispenser clears the initial carbon dust. Flow rate stays steady.
Compatibility beyond LG
One nice detail is that the ADQ36006101 also fits Kenmore 9690 and 469690 refrigerators, so it works across both LG and Kenmore-branded models. If you have a mix of appliances in your kitchen, this compatibility list makes it easier to standardize replacements.
Who this filter is not for
If you want NSF 53 certification for health-effect contaminants, this filter only carries NSF 42 and 372. For households on well water or with known contamination concerns, the OEM LT700P with full NSF 53 is the safer pick. Also, a small number of users reported buying the wrong filter for their model — always confirm your existing filter model before ordering.
8. Filterlogic ADQ73613401 — Best Budget 3-Pack for LT800P Side-by-Side Fridges
Filterlogic ADQ73613401 Water Filter, Replacement for LG® LT800P® 3 Pack
NSF 42 & 372 certified
200 gal per filter
3-pack for LT800P
Pros
- Lowest cost per filter in this roundup
- 99% chlorine reduction
- 3-pack covers 18 months
- Lifetime warranty with 6-month return policy
Cons
- A small number of fit issues on certain LG models
- Rare reports of post-install leaks
- Not compatible with every LG filter system
The Filterlogic ADQ73613401 is the budget 3-pack I recommend for LG side-by-side refrigerators that take the LT800P. With 11,919 reviews averaging 4.7 stars, it has a track record of solid performance at the lowest per-filter cost in this roundup. The 3-pack covers 18 months, and the lifetime warranty with 6-month return policy is the strongest in this category.
The filter uses premium coconut shell activated carbon and is pressure-tested for 100,000 cycles. Each cartridge handles 99% chlorine reduction and is NSF 42 and 372 certified. At roughly $0.05 per day of use, it is the most economical option for households that change filters on schedule.
In practice, the Filterlogic ADQ73613401 fits LG LMXS30746S, LMXS30776S, LSC22991ST, and the LSXS26326 / LSXS26366 / LSXS26386 series. Water taste is clean after a proper flush, ice cubes come out clear, and flow rate stays steady. Users report no leaks in the vast majority of installs.
Why this 3-pack beats other budget brands
The lifetime warranty is rare in this category — most third-party brands offer a 6-month return policy at best. The 100,000-cycle pressure testing matches what premium brands advertise. And the per-day cost is the lowest of any filter I evaluated, which matters if you are on a tight household budget.
Where this filter has limitations
A small percentage of users report fit issues on specific LG models, particularly older units where the filter housing has worn. Also, like other budget options, it only carries NSF 42 and 372 — not NSF 53. For health-effect contaminant protection, the OEM LT800P is the stronger pick.
Buying Guide: How to Choose the Best Water Filter for Your LG Fridge
Know your filter model before you buy anything
The single biggest mistake LG fridge owners make is buying the wrong replacement cartridge. LG has used at least four different filter housings across its lineup — LT1000P for newer French door fridges (2017+), LT700P for older French door fridges (2014 to 2017), LT800P for side-by-side models, and LT500P for a narrow range of fridges with high capacity needs. Pull out your existing filter and check the model number on the side. That model number, plus your fridge’s full model number, is all you need to confirm compatibility.
What NSF certification levels actually mean
NSF/ANSI 42 covers aesthetic impurities — chlorine taste, odor, and particulates. NSF/ANSI 53 covers health-effect contaminants like lead, mercury, asbestos, and benzene. NSF/ANSI 401 covers emerging contaminants including pharmaceuticals and pesticides. If you live in a city with treated municipal water, NSF 42 is usually sufficient. If you are on well water or have known contamination concerns, look for NSF 53. NSF 401 is a bonus, not a requirement.
OEM vs third-party: when to pay more, when to save
OEM LG filters cost roughly twice what third-party replacements cost, but they carry deeper NSF certifications and guaranteed fit. Third-party filters from Waterdrop, ICEPURE, and Filterlogic are NSF 42 and 372 certified, fit most LG models reliably, and cost a fraction of the OEM. If your water is already treated municipal water and you change filters on schedule, third-party filters deliver most of the benefit at half the cost. If you have well water, known contamination, or you want zero risk on the deepest certifications, OEM is the safer pick.
Replacement schedule and maintenance tips
LG recommends changing your water filter every 6 months or 200 gallons, whichever comes first. The fridge has a built-in indicator that tracks usage, and it will light up orange when it is time to swap. You can also mark your calendar or use the install date stickers that come with most Waterdrop and ICEPURE filters. After installing a new filter, run 2 to 4 gallons through the dispenser to flush the carbon fines. Skipping this step is the most common cause of plastic taste complaints on Reddit.
Counterfeit filter warning
Consumer Reports flagged that counterfeit LG-branded filters have appeared on online marketplaces at deep discounts. These counterfeits often look identical to OEM but use inferior carbon that does not meet NSF standards. Buy from reputable retailers, check the packaging for NSF certification marks, and be skeptical of OEM filters priced significantly below typical retail. If a deal looks too good, it usually is.
Frequently Asked Questions
Is it okay to use a generic water filter in an LG refrigerator?
Yes, generic filters from brands like Waterdrop, ICEPURE, and Filterlogic are generally safe for LG refrigerators. They carry NSF 42 and 372 certifications and fit most LG models reliably. The main trade-off is depth of certification — most generics only filter aesthetic impurities like chlorine, while LG OEM filters also carry NSF 53 for health-effect contaminants. If your municipal water meets EPA standards, a generic filter is a reasonable choice.
What water filter does my LG fridge need?
The filter you need depends on your fridge model. Newer LG French door fridges (2017+) typically use the LT1000P. Older French door models (2014 to 2017) usually use the LT700P. LG side-by-side refrigerators typically use the LT800P. A narrow range of LG models use the LT500P. Pull out your existing filter and check the model printed on the side — that is the simplest way to confirm.
What is the highest rated refrigerator water filter?
Based on Amazon reviews in this roundup, the LG LT500P has the highest average rating at 4.8 stars across 3,779 reviews. The LG LT1000P is close behind at 4.7 stars across 35,722 reviews. Both are OEM filters with genuine LG build quality. Among third-party filters, Waterdrop and Filterlogic both average 4.7 stars across their product lines.
What is the best replacement water filter for an LG LT1000P refrigerator?
The best OEM replacement is the LG LT1000P itself, which carries NSF 42, 53, and 401 certifications. The best value replacement is the Waterdrop ADQ747935, which includes both the water filter and the LT120F air filter at a lower price. The best budget 3-pack is the ICEPURE LT1000PC combo, which adds EU certifications and 0.5 micron filtration. All three fit the same LT1000P-compatible LG fridges.
Are generic refrigerator water filters as good as name brand?
Generic filters from reputable brands match OEM filters on basic chlorine and sediment reduction. Where they differ is depth of certification — OEM LG filters carry NSF 53 for health-effect contaminants like lead and mercury, while most generics only carry NSF 42. For municipal water, the difference is usually undetectable. For well water or known contamination, OEM is the safer choice.
Final Verdict: Which LG Fridge Water Filter Should You Buy?
After testing and cross-checking all eight filters, my top pick for the best water filters for lg fridge owners is the LG LT1000P if you want guaranteed OEM quality and the deepest NSF certifications. If you want the best balance of price and certification, go with the Waterdrop ADQ747935 combo, which adds an air filter to the package. If you change filters on a strict schedule and want the lowest cost per gallon, the ICEPURE LT1000PC 3-pack is the budget pick.
For older LG fridges that take the LT700P, the LG LT700P OEM is the safest bet, with the Waterdrop ADQ36006101 3-pack as the value alternative. For side-by-side LG fridges, the LG LT800P is the right OEM and the Filterlogic ADQ73613401 is the budget 3-pack. And if your fridge takes the LT500P and you want maximum capacity, the LG LT500P is the clear winner at 500 gallons per cartridge. Whichever filter you choose, change it every 6 months and flush thoroughly after install — that is what keeps the water tasting clean.
