Perfluorodecanoic acid
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. PFDA has been used in coatings on food packaging, furniture, upholstery, and carpeting, and as a lubricant, plasticizer, and corrosion inhibitor. Like many other PFAS, PFDA is resistant to breakdown in the environment and the body. High levels of ingested PFDA may result in adverse liver, developmental, and immune effects, but research on the health effects of PFDA is still ongoing.
EPA MCLG Level

Maximum level that poses minimal health risk based on the latest science
Health Effects
As with many PFAS compounds, research into the health effects of PFDA is rapidly evolving. Epidemiological studies have found associations with PFDA exposure and decreased antibody response to vaccines as well as increases in total and low-density lipoprotein cholesterol ('bad cholesterol'). Animal studies have also demonstrated associations between PFDA levels and liver toxicity, as well as developmental effects (low birth weight and offspring mortality).
Affected Organs & Systems:
Common Sources
- Not naturally occurring, so its widespread detection in surface and groundwater sources can be attributed to human release
- Includes wastewater discharge and industrial waste from PFAS manufacturing and processing facilities
- Elevated levels of PFDA may be found near industrial sites using PFAS
How to Remove It
Water filters certified under the following NSF standards are effective at removing Perfluorodecanoic 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
Perfluorodecanoic acid is classified as a PFAS contaminant.
This contaminant primarily affects the developmental, immune-system, and other systems.
