Best Water Filters for Fresno, Certified for PFAS

Matched to Fresno's own record: PFAS. Each option names the certification to check. Not a generic “best filters” list.

One need to treat. Nothing else detected.

Step 3 · Test first

Know what reaches your glass.

A tap test can confirm levels at your home before you choose treatment.

What this data doesn’t tell youPublic water-system monitoring reflects the system, not the water at an individual household tap at a given moment. Home plumbing, fixtures, storage, sampling location and timing can all change what actually reaches your glass.
Step 4 · Test your tap

Check your own tap before you buy

Fresno's record describes the water system, not the water at your tap. A home test kit or a certified lab shows what reaches your glass.

Questions

Frequently asked

What water filter do I need in Fresno?

Based on the published record: PFAS: PFOS 30 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024 (+9 more PFAS detected). This calls for reverse osmosis, or carbon certified for PFAS, certified to NSF/ANSI 53 or 58, with PFHxS/PFOA/PFOS/PFBS/PFHxA/PFNA/PFBA/PFHpA/PFPeA/PFPeS 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.
