LG LT700P water filter: which fridges it fits, and is it certified?
Last reviewed 2026-10-08.
LG's own page for the LT700P lists 120 compatible refrigerator models; 50 of them carry North American model numbers, such as LCFS22EXS, LFCS31626S, LFD22716ST, LFD22786SD (read 2026-10-08). NSF's listing for LG Electronics does not show it (read 2026-10-08), so we count no certified claim for it.
Which refrigerators the LT700P fits
LG lists the LT700P under part numbers ADQ36006101, AGF80300702, ADQ36006113, ADQ36006111, AGF80300701. Source: LG USA, LT700P product page.

Source: LG Canada, LT700P product page, read 2026-10-08. A model that is not on this list may still take the filter; the list is the maker's, not ours.
LG says the owner's manual states the filter model, that the model number is usually printed on the filter itself, and that its filter finder takes the refrigerator model number from the sticker inside the fridge. (LG USA: How to find the correct LG refrigerator filter for your model, read 2026-10-08.) Match that number, not the look of the cartridge.
Is it certified? What the listing says
The LG LT700P and the certified replacements below, from the certifiers' public listings. A ✓ under Lead claim means the NSF/ANSI 53 claim set names lead reduction; NSF/ANSI 401 is never read as a PFAS claim.

LT700P: NSF's LG Electronics listing shows the LT500P, LT600P and LT800P, not the LT700P. We could not search WQA's or IAPMO R&T's listings for it on 2026-10-08, so we neither count a certified claim nor say there is none. Check the certifier's listing for the model on the filter. Source: NSF listing, LG Electronics, read 2026-10-08.
What the maker states: LG's page states NSF42 and NSF53, a 200-gallon capacity and a 6-month interval. (LG USA, LT700P product page, read 2026-10-08.) A maker's statement is not a listing; the table above follows the listing.
Waterdrop: NSF lists these under Qingdao Ecopure Filter Co. as Waterdrop EFF-6032S (NSF listing, Qingdao Ecopure Filter (Waterdrop), read 2026-10-08). Waterdrop's plain WD-F32 is listed for NSF/ANSI 42 only. The WDS and WDP versions carry the NSF/ANSI 53 lead claim. Read the letters before WD on the box. A model with no Amazon link here is one we have not matched to an Amazon listing.
Genuine, certified replacement, or fake?
The genuine part is the one LG sells under the part numbers above; we could not find it in a certifier's listing, so the printed seal cannot be checked against one. A filter that copies the LT700P shape and prints "NSF certified" is only certified if its own model number is in a certifier's listing. Search the listing for the number on the filter, not the logo on the box. A certified replacement is not a counterfeit; an unlisted one is an unknown at any price. How counterfeits are caught and what to check: fake refrigerator water filters.

We do not test filters — we index what accredited certifiers publish, with attribution, and make no health or treatment claims. A certification covers a specific model against a specific standard; it is not a general seal of quality. We are not affiliated with NSF International.
