Does LG remove PFAS?
Last reviewed July 2026.
No — not on any listing we can find. LG says its filter is certified, including to NSF/ANSI 401. But we could not find a certifier's listing for the model we track, so there is no certified PFOA/PFOS claim to point to — and NSF/ANSI 401, even where a listing exists, is not a PFAS claim on any listing we read. The model notes below say what we searched and where.

LT1000P: No certifier listing for the LT1000P could be found (see the lead note), and LG's NSF and WQA listings for other models carry no PFOA or PFOS claim. Source: NSF listing, LG Electronics, read 2026-10-02.
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.
What does have a certified PFOA/PFOS 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 PFOA/PFOS claim with an accredited certifier, and the listing is public.
| Filter | Type | Claim certified by | $ / certified gallon |
|---|---|---|---|
| PLUS Pitcher & Dispenser Replacement Filter PUR PPF951K1 buy ↗ | pitcher | IAPMO R&T, NSF/ANSI 53-2024 | $0.375 |
| 5-Stage Replacement Filter (2-pack) ZeroWater ZR-002 buy ↗ | pitcher | IAPMO R&T, NSF/ANSI 53 | $1.233 |
How to check this yourself
Nothing here needs to be taken on trust. LG says its filter is certified; check that yourself by searching the three accredited certifiers' public databases — NSF International, WQA and IAPMO R&T — for the model number printed on the filter. When we searched, none of them listed it. If one does, the listing wins and we will update this page.

What "removes PFAS" actually covers
The certified claim is PFOA/PFOS reduction — the two legacy compounds the standards test for — or, on newer NSF/ANSI 53 listings, a total PFAS claim tested on a set mixture of seven compounds that includes PFOA and PFOS. Neither is "all PFAS", a family of thousands of chemicals. A certified filter is still the strongest verifiable option a pitcher or fridge filter can offer; just read the claim as written. Standards background: 42 vs 53 vs 401.
