Is LG NSF certified?
Last reviewed July 2026.
No certified lead claim we can verify. LG filters are on file with NSF, but for the models we track no certifier's listing shows a lead-reduction claim today. The model notes below say exactly what we found and where.

|---|---|---|---|---|---|
| LT1000P Refrigerator Water Filter LT1000P buy ↗ | 42 53 401 | ✗ | ✗ | no listing | not ranked |
LT1000P: LG states the LT1000P is certified to NSF/ANSI 42, 53 and 401 (lg.com). The NSF listing it cites (LG Electronics, read 2026-10-02) no longer shows the LT1000P, and IAPMO R&T and WQA searches did not find it either (waterfilterscore#14). The standards shown on our LG pages are LG's statement, and the LT1000P is left out of every certified ranking, until a listing is found (waterfilterscore#17). LG's LT800P is listed to 42 and 53 only.
The lead claim, model by model
LT1000P: LG says the LT1000P is certified to NSF/ANSI 42, 53 and 401. On 2026-10-02 we could not find it in any certifier's listing: NSF's LG Electronics listing shows the LT500P, LT600P and LT800P only, an IAPMO R&T model search returns third-party replacements only, and a WQA search for LT1000P returns nothing (waterfilterscore#14). Until a listing is found, we do not count a certified lead claim. Source: NSF listing, LG Electronics, read 2026-10-02.
What those standard numbers mean
- NSF/ANSI 42 — aesthetic effects (chlorine, taste and odour). Not a health claim.
- NSF/ANSI 53 — health effects. A certified lead or PFOA/PFOS claim is made under 53, but a 53 listing covers only the contaminants its claim set names: it is not automatically a lead claim.
- NSF/ANSI 401 — emerging compounds: pharmaceuticals, BPA, DEET, microplastics. On the listings we read, no 401 claim set includes PFOA or PFOS.
Verify it yourself: search NSF International, WQA and IAPMO R&T for the model number printed on the filter. If a listing turns up, the listing wins — tell us and we'll fix it.
What does have a certified lead claim
Ranked by cost per certified gallon — the only fair way to compare a $20 pitcher filter with a $50 fridge cartridge. Every one below holds a certified lead claim with an accredited certifier, and the listing is public.
