Does Waterdrop remove PFAS?
Based on the itemized NSF, WQA & IAPMO certified-model listings we track for Waterdrop (29 of 30 models).
What this means
Waterdrop’s certified filters do cover lead, chlorine, mercury, TDS (total dissolved solids) — but not PFAS. A brand can advertise that a filter “reduces” PFAS or is “tested to” a standard without the specific model being independently certified and listed — and that distinction is exactly what this site tracks.
You need reverse osmosis, or a filter specifically certified to NSF/ANSI 53 for PFAS. See every filter independently certified for it →
