Best Water Filters for Lakewood, Matched to Its Water
Matched to Lakewood's own record: PFAS. Each option names the certification to check. Not a generic “best filters” list.
One need to treat. Nothing else detected.
Each card starts from a finding in the published record. The certification is what to look for on the certifier’s listing (NSF, WQA or IAPMO) for the exact model.
PFAS
PFOS 18.5 ng/L, above the 4 ng/L limit (+1 more PFAS detected)
Reverse osmosis, or carbon certified for PFAS · NSF/ANSI 58 or 53, with PFOS/PFHxS named on the listing
Certified for a concern found here
Eligibility boundary. A product appears only when its registry-verified certification covers a need in the record. Verify the exact model and contaminant-specific certification before purchase: certification to a broad standard does not mean every contaminant claim under that standard applies to every model.
A product appears here only when a current certification record covers at least one identified concern; every concern stays listed. The retail offer is looked up afterwards and never changes which products appear or their order. As an Amazon Associate, PurityMap earns from qualifying purchases. Affiliate disclosure.

Frequently asked
What water filter do I need in Lakewood?
Based on the published record: PFAS (PFOS 18.5 ng/L, above the 4 ng/L limit (+1 more PFAS detected)) calls for reverse osmosis, or carbon certified for pfas, certified to NSF/ANSI 58 or 53, with PFOS/PFHxS named on the listing. Choose a model whose certification names each contaminant you need to treat.
Does "NSF certified" mean a filter removes everything?
No. Certification is per contaminant: a filter certified to NSF/ANSI 42 for chlorine taste says nothing about lead or PFAS. Check the certifier's listing (NSF, WQA or IAPMO) for the exact model and the exact contaminant.
