Does PUR Remove PFAS?
Not medical advice. Talk to your doctor about PFAS health concerns.
No. PUR does not remove PFAS. It holds NSF 42 and NSF 53. Both are real ratings. Both are proved by a third-party lab. But neither one covers PFAS. The mark for PFAS removal is NSF P473. PUR does not hold it.
Quick Verdict
PUR is a good filter for lead and chlorine. It is not a PFAS filter. For PFAS removal, buy the Clearly Filtered pitcher. It holds NSF P473. It costs about $90.
Check Clearly Filtered on AmazonWhat PUR Removes
PUR filters use carbon. Carbon removes chlorine, taste, and some metals. PUR PLUS adds a layer for lead. That is real. NSF tests prove it.
Here is what NSF 42 and NSF 53 cover:
- NSF 42: chlorine taste and odor.
- NSF 53: lead, mercury, and some metals.
Both are useful. If your concern is lead or taste, PUR works. If your concern is PFAS, it does not.
Why Carbon Cannot Catch PFAS
PFAS are small, slick molecules. Carbon traps things by holding them in tiny pores. PFAS pass right through. They do not stick well to carbon.
To catch PFAS, you need ion resin on top of carbon. Ion resin is a charged material. It binds PFAS and holds them. PUR does not use ion resin. That is why it cannot remove PFAS.
What NSF P473 Is
NSF P473 is the only mark for PFAS removal in water filters. It is a third-party test. A lab puts a known level of PFAS into water. It runs the water through the filter. Then it tests the output.
If PFAS drops below the safe limit, the filter earns P473. PUR does not hold this mark. Clearly Filtered does.
What Vets Should Know
Many vets worry about PFAS from base water, fire foam, or on-base housing. A PUR filter will not help with that. It removes lead and metals. PFAS needs a different filter type.
For PFAS peace of mind, you need NSF P473. Clearly Filtered is the easiest swap. It fits the same space as a PUR pitcher. No plumber. Works on day one.

PUR for PFAS — Pros and Cons
Pros
- NSF 42 and NSF 53 rated.
- Removes lead and some metals.
- Improves taste and odor.
- Widely available and easy to find.
Cons
- No NSF P473 mark.
- Does not remove PFAS.
- Filters last only 1 to 2 months.
- Not a PFAS solution for vets or base water concerns.
PUR vs Clearly Filtered for PFAS
PUR: carbon filter. NSF 42 and 53. No PFAS removal.
Clearly Filtered: carbon plus ion resin. NSF P473. PFAS removal proved by a third-party lab.
Both pitchers look the same on a shelf. The difference is in the filter inside. Clearly Filtered costs more. But it is the only pitcher type we trust for PFAS.

Does PUR remove PFAS?
No. PUR holds NSF 42 and NSF 53. NSF 42 covers taste and odor. NSF 53 covers some metals. Neither mark covers PFAS. The PFAS-specific mark is NSF P473. PUR does not hold it.
What does PUR actually filter?
PUR PLUS filters chlorine taste, odor, lead, mercury, and some metals. These are NSF 42 and NSF 53 claims. They are real and proved by a third-party lab. But PFAS is not on the list.
What is NSF P473?
NSF P473 is the only PFAS filter mark. A lab puts PFAS into water. It runs the water through the filter. Then it tests the output. If PFAS drops below the safe limit, the filter earns P473.
Which pitcher removes PFAS?
Clearly Filtered holds NSF P473. Tests showed 99.7% PFOA removal. It costs about $90. New filters last about 4 months. It is the same shape as a PUR pitcher.
Is PUR PLUS better than basic PUR for PFAS?
No. PUR PLUS adds lead removal. It does not add PFAS removal. Neither model holds NSF P473. Both are equal on PFAS — which is to say, neither removes it.
Does boiling water remove PFAS?
No. Boiling removes bacteria. It does not remove PFAS. Boiling water evaporates water but leaves PFAS behind. The PFAS level in the water can rise after boiling.
