Many filters say they "remove lead and PFAS". We looked each one up in the official certification listings on 20 October 2026 and again on 26–27 October 2026. This is what we found.

"Certified" here means: a third-party certifier (IAPMO R&T or WQA) lists the exact model under NSF/ANSI 53 (or 58 for reverse osmosis) with a lead claim and a PFAS claim. We list the model numbers exactly as the certifier does. Buy the model, not the brand.

"PFOA/PFOS" and "Total PFAS" are two different claims a certifier can list under NSF/ANSI 53. We show the wording each listing uses. Capacity is the gallons the listing gives before the filter must be replaced.
Waterdrop G3P800 at Waterdrop (check the current price) →Watch for "NSF/ANSI 372" on a box. It certifies that the filter's own parts are lead-free. It says nothing about removing lead from your water.
Your water utility publishes a free yearly water quality report (Consumer Confidence Report). If it shows no lead concern and no PFAS, and your home has no lead service line or old lead plumbing, buying nothing is a fine answer. The report covers the water at the street; lead can still come from your own pipes (EPA). If it does, pick from the table above and run the numbers for your household — filters are a yearly cost, not a one-time one.
