Perfluorododecanoic acid
Perfluorododecanoic acid (PFDoA) is part of a class of synthetic compounds known as per- and polyfluoroalkyl substances (PFAS) widely used to make products more resistant to stains, water, and grease. It is found as a breakdown product of food packaging, sofas, and carpets. Like many other PFAS, PFDoA is highly persistent in the environment and the body. More research is required to understand the health effects of PFDoA, but elevated levels have previously been associated with liver toxicity.

Health Effects
As with many PFAS compounds, research into the health effects of PFDoA is rapidly evolving. Animal studies have shown associations between elevated PFDoA levels and liver toxicity.
Affected Organs & Systems:
Common Sources
- PFDoA is not naturally occurring, so its widespread detection in surface and groundwater sources can be attributed to human release. This includes wastewater discharge and industrial waste from PFAS manufacturing and processing facilities. Elevated levels of PFDoA may be found near industrial sites using PFAS.
How to Remove It
Water filters certified under the following NSF standards are effective at removing Perfluorododecanoic acid:
EPA MCLG Level
The EPA MCLG represents the maximum level that poses minimal health risk based on the latest scientific research. It's often more protective than federal legal limits.
Contaminant Type
Perfluorododecanoic acid is classified as a PFAS contaminant.
This contaminant primarily affects the liver.
