Best Water Filters for Avondale, Matched to Its Water
Matched to Avondale's own record: PFAS, lithium. Each option names the certification to check. Not a generic “best filters” list.
Two needs 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
PFOA 13.5 ng/L, above the 4 ng/L limit (+7 more PFAS detected)
Reverse osmosis, or carbon certified for PFAS · NSF/ANSI 58 or 53, with PFOA/PFOS/PFBS/PFHxA/PFHxS/PFBA/PFHpA/PFPeA named on the listing
Lithium
Lithium 114 µg/L, above the 10.0 µg/L EPA health reference level (above a health screening level, not a legal limit)

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 Avondale?
Based on the published record: PFAS (PFOA 13.5 ng/L, above the 4 ng/L limit (+7 more PFAS detected)) calls for reverse osmosis, or carbon certified for pfas, certified to NSF/ANSI 58 or 53, with PFOA/PFOS/PFBS/PFHxA/PFHxS/PFBA/PFHpA/PFPeA named on the listing; Lithium (Lithium 114 µg/L, above the 10.0 µg/L EPA health reference level; above a health screening level, not a legal limit): if you choose to filter, look for depends on the contaminant, certified to The certifier's listing for each named contaminant. 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.
