PFAS Water Filter Pitchers
A pitcher can reduce PFAS only if its filter is certified for PFOA and PFOS reduction, usually under NSF/ANSI 53, so check the specific filter model rather than the brand. Pitchers are the lowest-cost way to start, but small filters need frequent changes and the cost per gallon is higher than under-sink options.
What to compare
- Certification: PFOA/PFOS on the performance data sheet or listing for that filter cartridge.
- Capacity: often 40 to 120 gallons per filter. Mark the change date.
- Other claims: many PFAS-certified pitchers also list lead reduction.
- Filtering speed: dense filters can be slow. Plan for a full pitcher in the fridge.
- Cost per gallon: filter price divided by rated gallons.
- Size: 6- to 10-cup pitchers fit most fridge doors. Dispensers hold more.

FAQs
Do water filter pitchers remove PFAS?
Some do. Pitchers whose filters are certified to NSF/ANSI 53 for PFOA and PFOS reduction have been tested to reduce those compounds. Many standard pitcher filters are not certified for PFAS. Check the filter model's certification listing or data sheet, and replace it at the rated gallons.
Which pitcher filter is certified for PFOA and PFOS?
Several brands, including some Brita, ZeroWater and other pitcher filters, list certified PFOA/PFOS reduction on specific filter models. Certifications change as products are updated, so verify the current listing on the NSF, WQA or IAPMO website by model number before buying.
How often should I change a PFAS pitcher filter?
At or before the rated capacity, often 40 to 120 gallons or about 2 to 6 months for a typical household. Certified PFAS reduction only applies within that capacity, and carbon becomes less effective as it fills. Use the pitcher's indicator or set a calendar reminder.
