The short answer

For household PFAS in drinking water, **under-sink reverse osmosis with a model-specific NSF/ANSI 58 PFAS claim** is the most consistent barrier across short- and long-chain chemistry when maintained. Certified **NSF/ANSI 53 carbon** is a strong value path for many long-chain profiles. Pitchers help only when the exact model is listed. See the [EPA filter identification guidance](https://www.epa.gov/water-research/identifying-drinking-water-filters-certified-reduce-pfas).

EPA set maximum contaminant levels for PFOA and PFOS at **4.0 ppt**, with additional MCLs and a hazard index for other PFAS. Hardware only works after you map the contaminant, match a certified claim, and budget for media changes. This roundup ranks options by treatment realism—not brand catalogs.

## How to use this ranking

Read items as engineering classes. Verify the model number in an accredited directory, install at the kitchen for ingestion risk, and re-test high-risk wells.
