How to Remove PFAS From Water (2023 Ultimate Guide)

In the past years PFAS was big news when it was uncovered that it had been contaminated with harmful amounts. However exposure to PFA does not happen in bottled water. Your home’s water and well water may contain PFAS because the pollutants in the neighborhood are harmful. This guide covers PFAS origins and U.S. health and safety hazards. Tables for content.


These two PFAS have been eliminated as they are commonly used and dangerous and have now been phased out of use: Perfluorooctanol. Both of these PFAS chemicals are traditionally used to manufacture several popular consumer product categories. Both substances have toxic bioaccumulation properties which are considered to have an eternal life cycle, which can last up to a hundred years in the earth.

How to reduce PFAS in your drinking water, according to experts

Editors Note: Find inspiration from our monthly round up about the importance of living well. Join CNNs Life but Better to receive information that will help improve our wellbeing. Drinkable water in America is expected to become safer for the environment and less harmful to the environment than other water sources. Perfluoraloalkyls and polyfluoroalkylls or PFAS are thousands of chemical species which are not readily breakable within the environment. PFAS can cause health problems like high blood cholesterol and high blood pressure as well as heart disease, diabetes or obesity.

Testing your water

It would probably take three to four years before a person starts noticing PFAS in the air. How should consumers control the amount they put in contaminated drinking water? See how high PFAS levels in your local water system are. PFAS, a nonpartisan advocacy organisation has created a national water database searchable with zip codes listing PFAS and other contaminated substances, and also a national map showing where PFAS is found. However most rural homes and businesses largely rely on wells.

What are the health effects of PFAS?

PFAS has various medical benefits, such as reproductive development and immunological issues. Since PFAS are prone to deterioration and accumulate throughout the body, the longer exposure to them the better. EPA cited data that links PFAS exposures:

???? Health Risks Associated With PFAS

The Environmental Protection Agency has issued the highest health advisory level for the maximum contamination level based on EPA data. PFAS can cause severe health risks to humans even after it is taken in water. PFAS can have a range of health hazards including:

Activated carbon filtration

Carbon filters contain activated carbon with numerous pores throughout their surface and infrastructure. PFAS and other contaminates are collected through a process referred to as adsorption, and cleaned water is produced. Get a quick overview of activated carbon filtering 101.

Low Birth Weight

The study also showed that when parents of infants were in high PFAS concentrations they had an increased risk of developing weight problems and fewer chances of gestational age. Not only did infants’ natal weight increase, but babies also experienced stunted growth over their first few years of life. In addition PFOS can reduce the chance that pregnant women get pregnant.

How to remove PFAS from water

The removal of PFAS in water is done via reverse-osmosis activated carbon filters and iodification.

Immune System Effects

PFAS can decrease immune response to pathogens and decrease resistance. Additionally PFAS exposure may hinder the production of the level of antiviral antibodies needed to respond to vaccines, an issue especially exacerbated by COVID-19 pandemics.

Ion Exchange Systems

Another method of reducing drinking water PFAS is ion exchange. An ions exchange system comprises a tank that contains an anion resin usually produced from insoluble hydrocarbons. It is possible to manufacture ions using an anionic resin or cationic resin. Specifically anionic resins have negative charges, making them better for removal of negatively charged particles. Both resin beds act like magnets, and attract particular contaminants to the surface and cannot get into water.

Reverse Osmosis Systems

Generally referred to by many as the largest filtration solution of all time, filtration systems have remained the most efficient. In reverse osmosis water passes over a semi-permeable membrane which has a small pores of approximately 0.0005. Although the size of the pores PFAS is often smaller than the membrane pores, they are not able to absorb the water particles. Reverse Osmosis filters typically reduce PFOA & PFOS by about 90%.

???? How to Test for PFAS in Water?

PFOAs can’t be seen by humans, and they can’t be smelled or tasted. They are even safer. Before removing PFOA from the water however you must ensure the water contains it. The best solution is water testing. It’s possible to have your water tested using your water test kit at one of many laboratories.

Activated Carbon Filters

A series of activated carbon cartridges can remove PFOA from household drinking water sources. The EPA says activated carbon filter technology is the most researched water treatment option available in the US. Activated carbon-fiber filter filters absorb a wide variety of water contaminants.

Will boiling water remove PFAS?

No boiling water alone won’t kill PFOS / PFOA because it cannot be removed through either evaporation / condensation or filtering process. Basically boiling the water will cause dissolved particles and the corresponding PFAS concentration within smaller water.

???? Which Water Filters Are Best For PFOS and PFOA Removal?

Tell me about the easiest way to make an informed decision? Depending upon the search criteria the answers can vary. If your system only removes the PFAS, then carbon filtration or exchange of ions is the most ideal solution. Reverse osmosis filtering can also be an option for those wanting to eliminate PFAS and contaminants in drinking water and reduce health risks. Your budget could influence your purchase decisions.

What does it mean if a product is certified by NSF International for PFAS removal?

The PFOA or FOS in a product must be tested independently for its ability to reduce to less than 70 ppt. It’s a good sign of the confidence you’re giving your buyers because you have absolute assurance a product does what the advertised product does. Please see the certification page at NSF for more info on products approved to be removed from PFOS and PFOA.

Are any other technologies capable of PFAS removal?

Several. Distillation has a powerful capacity to remove these chemicals from water. The distillation process could take around 4 hours to make a simple batch of chemical water. It’s not a simple cleanwater solution.
