Does Brita Filter PFAS? What the Testing Actually Shows
Brita is the best-selling water filter in the US. But if you have PFAS in your water, the short answer is: standard Brita filters do not remove PFAS. Upgraded Brita models reduce some compounds — but none of them hold the certification that matters.

Brita Filter Models vs PFAS Removal
| Filter Model | PFAS Removal Claim | NSF P473 Certified? |
|---|---|---|
| Standard Brita Pitcher | No significant removal | No |
| Brita Longlast+ | Reduces some PFOA / PFOS (internal testing) | No NSF P473 |
| Brita Elite | Some reduction claimed (internal testing) | No NSF P473 |
| Brita Stream | No PFAS removal | No |
| Clearly Filtered Pitcher | 99%+ PFOA / PFOS removal (independent testing) | Yes — NSF P473 |
| Reverse Osmosis (APEC, SpringWell) | 99%+ of all PFAS compounds | Yes — NSF 58 + WQA tested |
Why Pitcher Filters Struggle with PFAS
PFAS removal through activated carbon requires long contact time and dense filter media. Pitcher filters have two structural disadvantages:
Short contact time
Water flows through a pitcher filter by gravity in seconds. Under-sink and whole-house filters with slower flow rates allow more PFAS molecules to bind to carbon. The faster the flow, the less PFAS is captured.
Limited carbon density
Pitcher filters have a small volume of filter media compared to under-sink systems. Less media means lower capacity to capture PFAS — and faster saturation when PFAS levels are high.
Not all PFAS compounds bind to carbon
Short-chain PFAS compounds (like GenX and PFBS) are less well-removed by activated carbon than long-chain PFAS like PFOA and PFOS. A standard pitcher filter may do little to nothing for these newer replacement PFAS.
What Actually Removes PFAS
Two technologies have strong, consistent PFAS removal records:
NSF P473 certified pitcher / under-sink filters
Clearly Filtered uses a proprietary Affinity Filtration process that holds NSF P473 certification for PFOA and PFOS removal. Independent testing shows 99%+ reduction. Aquasana also carries NSF P473 for its under-sink line.
Reverse osmosis (RO) systems
RO pushes water through a semi-permeable membrane that physically blocks PFAS molecules. 99%+ removal of PFOA, PFOS, GenX, and most other PFAS compounds. Certified under NSF 58. Requires installation under a kitchen sink with a dedicated tap.

Common Questions
Does a standard Brita pitcher filter PFAS?+
No. Standard Brita pitchers use a basic activated carbon filter that removes chlorine taste and some heavy metals but does not meaningfully remove PFAS compounds. Brita's standard filter is not tested or certified for PFAS removal under NSF P473 or NSF 58.
Does the Brita Longlast+ remove PFAS?+
Brita claims the Longlast+ reduces some PFOA and PFOS, but the filter is not certified under NSF P473 — the standard designed specifically for PFAS removal in pitcher and under-sink filters. Without independent NSF P473 certification, the removal claims are based on Brita's own internal testing rather than third-party verification. For documented PFAS concerns, this is not the standard you want to rely on.
What is NSF P473 certification?+
NSF P473 is an independent certification standard specifically for PFAS removal in drinking water treatment units. It covers PFOA and PFOS reduction. Products that earn NSF P473 certification have been independently tested and verified to remove these compounds to below health advisories. Clearly Filtered and Aquasana hold NSF P473 certification. Brita does not hold NSF P473 certification on any of its pitcher filter models.
Is ZeroWater better than Brita for PFAS?+
Yes, ZeroWater performs better than Brita for PFAS. ZeroWater's 5-stage ion exchange filter removes more contaminants than basic activated carbon. Duke University and EWG testing found meaningful PFAS reduction with ZeroWater. However, ZeroWater is also not NSF P473 certified, so it falls short of the certified standard. For confirmed PFAS contamination, a certified filter (Clearly Filtered) or reverse osmosis system is the more reliable choice.
What pitcher filter actually removes PFAS?+
Clearly Filtered is the gold standard pitcher for PFAS — it holds NSF P473 certification and removes 99%+ of PFOA and PFOS in independent testing. It costs more than Brita (around $80 for the pitcher, $60 per replacement filter) but it is the only widely available pitcher with verified PFAS removal. For a step up, a reverse osmosis under-sink system removes 99%+ of PFAS and handles compounds that some pitcher filters miss.
