# LG LT1000P Refrigerator Water Filter: Which Part Numbers Fit, the 200 Gallon Interval, and What Differs From the LT1000PC and LT700P > LG LT1000P (ADQ74793501) is rated 200 gallons or 6 months and listed to NSF/ANSI 42, 53 and 401 by LG. It does not fit LT700P refrigerators. | | | |---|---| | Source | https://ownerspec.com/water/parts/lg-lt1000p-refrigerator-filter/ | | Publisher | OwnerSpec (https://ownerspec.com/) | | Published | 2026-09-12 | | Updated | 2026-09-12 | | Facts verified | 2026-09-12 | | Disclosure | Contains affiliate links.

The same page lists it to NSF/ANSI 42, 53 and 401, and no cross-fit on this page claims all three: AQUA CREST AQF-FF46AF01 and ICEPURE RWF4700AC claim 42 and 372, GLACIER FRESH GF-1000P names 42, and Waterdrop WD-LT1000P names no standard number at all. The LT1000PC in Amazon listing titles is the same cartridge only according to retailer Q&A, not any LG document. The LT700P does not fit: LG lists it as a separate product with its own part-number family (ADQ36006101 and four others) despite an identical 200 gallon, 6 month rating. The spec that must match is the part number on the old cartridge, because LG publishes no flow rate, micron rating or dimension for the LT1000P that a cross-fit could be checked against. ## Fact sheet - **Answer:** The LG LT1000P is sold under part numbers ADQ74793501, AGF80300704, AGF80300705, ADQ74793507 and AGF80300703, and LG's product page rates it at 200 gallons or 6 months and lists it to NSF/ANSI 42, 53 and 401. It does not fit refrigerators that take the LT700P, which LG lists as a separate product with its own part-number family. - **Applies to:** LT1000P; Part number on the old cartridge: ADQ74793501 or one of the four alternates - **Compatibility basis:** LG LT1000P product page (lg.com), which prints the part numbers, the 200 gallon / 6 month rating and the NSF/ANSI 42, 53 and 401 listing - **Assumptions:** Every certification on this page is as stated on the maker's own page; none was confirmed against the NSF listing database, which is form-driven and could not be queried by URL this session.; Compatible refrigerator model numbers (LFXS26973S, LMXS28626S, LFXC22526S, Kenmore 46-9980) come from retailer cross-reference listings, not from an LG document; LG routes buyers to a model-number lookup tool instead of printing a list.; The claim that LT1000PC is the same cartridge in different packaging traces only to retailer Q&A and is unconfirmed on an LG document. - **Method:** Part numbers, capacity, interval and standards read from the LG LT1000P and LT700P product pages and LG's refrigerator-filter support page; cross-fit figures read from each maker's own product page. Every figure is the maker's published spec; nothing was tested. - **Primary source:** [LG, LT1000P Replacement Refrigerator Water Filter product page (part numbers, 200 gallon / 6 month rating, NSF/ANSI 42, 53, 401)](https://www.lg.com/us/appliances-accessories/lg-lt1000p-refrigerator-water-filter) (manufacturer or vendor document) - **Facts verified:** 2026-09-12 - **Last updated:** 2026-09-12 - **Canonical URL (cite this):** https://ownerspec.com/water/parts/lg-lt1000p-refrigerator-filter/ If the label on the old cartridge starts ADQ36006 or reads LT700P, this is the wrong page: that is the earlier LG cartridge, and an LT1000P will not fit it whatever the rating on the box says. ## Which LG and Kenmore refrigerators take the LT1000P? LG's product page prints the part numbers but sends buyers to a model-number lookup tool instead of a static compatibility list, so the model numbers below come from retailer cross-reference listings, not from LG. The number to trust is the one on the old cartridge. | Number | Where it appears | What it means | |---|---|---| | ADQ74793501 | LG LT1000P product page | The primary LG part number for the LT1000P | | AGF80300704, AGF80300705, ADQ74793507, AGF80300703 | LG LT1000P product page | The same cartridge under LG's alternate part numbers | | ADQ75795105 | Amazon listing title for the genuine filter | Retailer data; not on the LG page fetched this session | | MDJ64844601 | Cross-fit listing titles (AQUA CREST, Waterdrop, GLACIER FRESH) | Not confirmed as an LG part number on any LG page this session | | LT1000PC | Every cross-fit listing title, plus retailer Q&A | Said to be the same cartridge in different packaging; unconfirmed on an LG document | | LFXS26973S, LMXS28626S, LFXC22526S, Kenmore 46-9980, Kenmore Elite 9980 | Amazon and Home Depot listings | Refrigerator models retailers list as taking the LT1000P; retailer data only | LG's page states the cartridge reduces 99.9 percent of bisphenol A and 99.9 percent of asbestos, with mercury, lead and benzene described as "almost all" and no figure. Lead is an NSF/ANSI 53 claim, explained in the [lead guide](/water/guides/lead-in-tap-water-service-line/); NSF/ANSI 42 covers [chlorine taste and odour](/water/guides/chlorine-chloramine-city-water/). ## What else fits the same housing? Four cross-fits sell for the LT1000P housing, and every figure in the table is the maker's own published spec, read from its product page and not tested here. Where a maker prints nothing, the cell says so. | Cartridge | Capacity and interval | Micron and flow | Certification, as stated on the maker's page | Sourced by LG? | |---|---|---|---|---| | LG LT1000P | 200 gallons, 6 months | Not published | NSF/ANSI 42, 53, 401 | Yes | | AQUA CREST AQF-FF46AF01 | 200 gallons; interval not published | Micron not published; 0.5 GPM; 20-100 psi; 33-100 F | NSF/ANSI 42 and 372 | No; page states it is not sourced by or sponsored by LG | | ICEPURE RWF4700AC | Not published | 0.5 micron outer layer; flow not published; 97.5 percent chlorine reduction | NSF/ANSI 42 and 372 (IAPMO lead-free) on the maker's page; the water-only Amazon listing names 42 only | No; the maker calls it "a compatible spare part" | | Waterdrop WD-LT1000P | 200 gallons, 6 months | 0.5 micron pore size; flow not published | "Certified by NSF International", no standard number named | No | | GLACIER FRESH GF-1000P | 200 gallons, 6 months | 0.5 micron pore size; flow not published; 97.9 percent chlorine reduction | NSF/ANSI, IAPMO, ISO named; NSF 42 named specifically | No; page states it is not sourced by or sponsored by LG | Two listing traps: the AQUA CREST and ICEPURE Amazon pages open on a 3 water plus 3 LT120F air filter combo, so the links above go to each brand's water-only variant, sold only in 2, 3 or 4 count. Waterdrop is the only cross-fit sold singly, and ICEPURE sells the same base filter as RWF4700A, RWF4700AB and RWF4700AC, so check the pack count, not the SKU. The LT700P prints the same 200 gallon, 6 month rating and NSF/ANSI 42 and 53 on LG's LT700P page, but it is a different housing with its own part-number family (ADQ36006101, AGF80300702, ADQ36006113, ADQ36006111, AGF80300701) and its own page on this site. ## How often does it need replacing? LG's product page gives one figure: 200 gallons or 6 months, whichever comes first. LG publishes no condition that shortens it and no flow rate, so a slowing dispenser is the only sign the reader has before the 6 months are up. | Cartridge | Maker's interval | Operating limits the maker prints | |---|---|---| | LG LT1000P | 200 gallons or 6 months | None published | | AQUA CREST AQF-FF46AF01 | 200 gallons; no time interval | 20-100 psi, 33-100 F | | ICEPURE RWF4700AC | Not published | Not published | | Waterdrop WD-LT1000P | 200 gallons or 6 months | Not published | | GLACIER FRESH GF-1000P | 200 gallons or 6 months | Not published | A household that dispenses more than 200 gallons in 6 months hits the gallon limit first; at roughly 1 gallon a day (about 180 gallons in 6 months) the time limit arrives first. LG publishes no metering figure, so a heavy user has to count for themselves. ## How do you spot a counterfeit? LG's refrigerator-filter support page says counterfeit, deceptively labeled and third-party filters are not guaranteed to filter properly, may cause damage not covered under the LG warranty, and should be avoided by buying directly from LG. The same page states only genuine LG filters are tested and certified by NSF International. LG publishes no physical check on that page: no hologram, no label test, no serial lookup. The only LG-endorsed check is the seller, plus a box number matching one of the five LG prints. A cross-fit that labels itself not LG-sourced is not a counterfeit; a box claiming to be LG with a number LG does not print is the case the warning covers. **Genuine or cross-fit** The genuine cartridge's flaw is price; every cross-fit's flaw is the standards list, 42 and 372 at best against LG's 42, 53 and 401. If you filter for lead or another NSF/ANSI 53 contaminant, buy the LG LT1000P and stop reading. If you filter for chlorine taste, Waterdrop WD-LT1000P is the one cross-fit sold singly and GLACIER FRESH GF-1000P the one that prints a chlorine figure (97.9 percent) and names NSF 42. If the pressure and temperature range or the 0.5 GPM flow figure is what you check against your refrigerator's line, AQUA CREST AQF-FF46AF01 is the only cross-fit that publishes 20-100 psi, 33-100 F and a flow rate at all. Skip it if NSF/ANSI 53 or 401 is what you need, since it claims only 42 and 372. Buy nothing until you have read the old cartridge's number: an ADQ36006 prefix means the LT700P, and none of these fit. ## The picks - **LG LT1000P genuine (ADQ74793501)**: The only cartridge LG lists to NSF/ANSI 53 and 401 (200 gallons or 6 months per LG; NSF/ANSI 42, 53, 401 per LG's page; single-filter listing, 2-pack and 3-pack variants on the same page) Amazon: https://www.amazon.com/dp/B074HLRXMP/?tag=ownerspec-20 - **Waterdrop WD-LT1000P**: Cross-fit sold as a single filter, water-only (200 gallons, 6 months, 0.5 micron per Waterdrop; states NSF certified without naming a standard; 1 to 4 count on the listing) Amazon: https://www.amazon.com/dp/B07GDPSXB3/?tag=ownerspec-20 - **AQUA CREST AQF-FF46AF01 (3-pack, water-only)**: Cross-fit with the most published operating figures (200 gallons, 0.5 GPM, 20-100 psi, 33-100 F, NSF/ANSI 42 and 372 per AQUA CREST; 2 or 3 count only) Amazon: https://www.amazon.com/dp/B0CSCL58JG/?tag=ownerspec-20 - **GLACIER FRESH GF-1000P (3-pack)**: Cross-fit that names NSF 42 and prints a chlorine figure (200 gallons, 6 months, 0.5 micron, 97.9 percent chlorine reduction per GLACIER FRESH; NSF 42 named; 2 to 4 count) Amazon: https://www.amazon.com/dp/B07XY63ZDS/?tag=ownerspec-20 ## Frequently asked questions ### How often should the LG LT1000P be replaced? LG's LT1000P product page rates the cartridge at 200 gallons or 6 months, whichever comes first. LG publishes no condition that shortens the interval, and no flow rate or micron rating to check it against. The cross-fits that publish a figure (Waterdrop WD-LT1000P and GLACIER FRESH GF-1000P) copy the same 200 gallon, 6 month rating on their own product pages. ### Which NSF/ANSI standards is the genuine LT1000P listed to? LG's product page lists the LT1000P to NSF/ANSI 42, 53 and 401. That is the maker's statement: the NSF listing database could not be queried by URL this session, so the listing was not confirmed there. LG's support page adds that only genuine LG filters are tested and certified by NSF International, which is LG's claim about third-party cartridges, not an NSF finding. ### Does an LT1000P fit a refrigerator that takes an LT700P? No. LG lists the LT700P as a separate product with its own part-number family (ADQ36006101, AGF80300702, ADQ36006113, ADQ36006111, AGF80300701) even though its product page prints the same 200 gallon, 6 month rating. The LT700P page lists that cartridge to NSF/ANSI 42 and 53 only; the LT1000P adds 401. Match the number on the old cartridge, not the rating. ### Is the LT1000PC the same filter as the LT1000P? Retailer listings and retailer Q&A on Amazon and Best Buy say LT1000PC is the same cartridge in different packaging, and every cross-fit listing on this page carries LT1000PC in its title. No LG document fetched this session confirms that, so the page treats it as unconfirmed. LG's own page prints LT1000P and the five ADQ and AGF part numbers, nothing else. ### How does LG say to avoid a counterfeit LT1000P? LG's refrigerator-filter support page says counterfeit, deceptively labeled and third-party filters are not guaranteed to filter properly, may cause damage not covered under the LG warranty, and tells buyers to purchase directly from LG. It publishes no physical check such as a hologram or a label test, so the only LG-endorsed check is the seller, not the cartridge. ## Sources - [LG, LT1000P Replacement Refrigerator Water Filter product page (part numbers, 200 gallon / 6 month rating, NSF/ANSI 42, 53, 401)](https://www.lg.com/us/appliances-accessories/lg-lt1000p-refrigerator-water-filter) (manufacturer or vendor document) - [LG, LT700P Replacement Refrigerator Water Filter product page (part numbers, 200 gallon / 6 month rating, NSF/ANSI 42 and 53)](https://www.lg.com/us/appliances-accessories/lg-lt700p-refrigerator-water-filter) (manufacturer or vendor document) - [LG Support, Refrigerator water filters: counterfeit and third-party filter statement](https://solutions.lg.com/us/kitchen/refrigerator-filters) (manufacturer or vendor document) - [AQUA CREST, replacement for LG LT1000P / LT1000PC product page (200 gallons, 0.5 GPM, 20-100 psi, 33-100 F, NSF/ANSI 42 and 372)](https://aquacrestfilter.com/products/aquacrest-refrigerator-water-filter-replacement-for-lg%C2%AE-lt1000p%C2%AE-lt1000pc-lt-1000pc-and-lt120f%C2%AE) (manufacturer or vendor document) - [ICEPURE, RWF4700 replacement for LG LT1000P product page (NSF/ANSI 42 and 372, 97.5 percent chlorine reduction, 0.5 micron outer layer)](https://icepurefilter.com/product/icepure-rwf4700ab-fits-for-lg-lt1000p-adq747935-adq74793501-adq74793502-mdj64844601-lfxs26973s-lmxs28626s-lfxs26596s-lfxc22526s-lfxs28968s-lmxs28626s-lfcs27596s-lfx28978st-kenmore-elite-9/) (manufacturer or vendor document) - [Waterdrop, WD-LT1000P replacement for LG LT1000P product page (200 gallons, 6 months, 0.5 micron)](https://www.waterdropfilter.com/products/lg-lt1000p-refrigerator-water-filter) (manufacturer or vendor document) - [GLACIER FRESH, GF-1000P replacement for LG LT1000P product page (200 gallons, 6 months, 0.5 micron, 97.9 percent chlorine reduction, NSF 42)](https://glacierfreshfilter.com/products/lg-adq747935-mdj64844601-replacement-refrigerator-water-filter-by-glacier-fresh-3-pack) (manufacturer or vendor document) --- Citation: OwnerSpec, "LG LT1000P Refrigerator Water Filter: Which Part Numbers Fit, the 200 Gallon Interval, and What Differs From the LT1000PC and LT700P", https://ownerspec.com/water/parts/lg-lt1000p-refrigerator-filter/, facts verified 12 September 2026.
