Matched to what EPA's records actually show for STOCKBRIDGE (grade A, 96/100) — not to what sells.

Reverse osmosis or a PFAS-tested carbon block. EPA's UCMR5 sampling of STOCKBRIDGE detected PFBS, PFHxA, all below federal MCLs. RO removes both long- and short-chain PFAS; a carbon block certified for PFOA/PFOS is the lower-cost option for PFOA/PFOS-only detections, provided cartridges are changed on schedule.
Optional but sensible. STOCKBRIDGE's results are below federal limits, so reverse osmosis or a pfas-tested carbon block is a precaution rather than a necessity.
Reverse osmosis or a carbon block certified for PFOA/PFOS. RO covers short-chain PFAS too; a certified carbon block is the cheaper option for the PFOA/PFOS-only detections found here.
STOCKBRIDGE's latest Lead and Copper Rule 90th-percentile result was 0 ppb (2023-01-01 to 2025-12-31), below the 15 ppb action level. Lead enters from service lines and home plumbing, so test at the tap if your home is older.
Yes. UCMR5 sampling (2025-02-11 to 2025-11-04) detected PFBS, PFHxA, all below federal MCLs. RO and PFOA/PFOS-certified carbon filters reduce them.
Look for: NSF/ANSI 58 (RO) or NSF/ANSI 53 with a PFOA/PFOS claim (formerly NSF P473)

Utility data describes water leaving STOCKBRIDGE. Lead, copper and some PFAS enter between the main and your faucet, so a mail-in lab test is the only way to know what your household actually drinks — and the cheapest way to avoid buying a filter you do not need.
