Does LG remove PFAS?

Last reviewed July 2026.

Yes — LG holds a certified PFOA/PFOS claim. Not marketing copy: an accredited certifier lists it, and you can look the listing up.

Model by model

LT1000P: NSF-listed to NSF/ANSI 42, 53 and 401. LG's LT800P is listed to 42 and 53 only — the 401 emerging-contaminant claim does not carry across the LT line.

What the certified claim costs to run

Certification is per model, and so is the running cost. The cheapest LG model carrying the claim is the LT1000P Refrigerator Water Filter (LT1000P) at about $54.99 per filter for a certified 200 gallons — $0.275 per certified gallon.

That capacity is what the certifier tested to, not a marketing estimate. For one person drinking about half a gallon a day it is roughly 13 months per filter; for a family of four, closer to 3 months. Run past the rated capacity and the claim no longer applies — the media is exhausted even though the filter still passes water.

How to check this yourself

Nothing here needs to be taken on trust. LG's certifications are held by NSF, and each keeps a public database you can search by brand or model number. Look up the model printed on the filter — not the box, not the retail listing — and read which standards the entry lists. A model certified to 42 only will say exactly that.

What "removes PFAS" actually covers

The certified claim is PFOA/PFOS reduction — the two legacy compounds the standards test for — not "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.
