Does LG remove lead?

Last reviewed July 2026.

Yes — and it's certified, not just claimed. Every LG filter we track holds NSF/ANSI 53, the health-effects standard where lead lives, from an accredited certifier. That means the lead claim is in a public listing you can check — not just on the box.

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.

Why 53 is the number that matters

NSF/ANSI 42 is aesthetics — chlorine, taste, odour. 53 is health effects, and it is where the lead claim lives. A filter can be honestly "NSF certified" and still filter nothing but taste — see 42 vs 53 vs 401.

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.
