How PFAS Can Be Filtered Out of Water
Hearing about chemicals like PFAS in your drinking water can be concerning. After all, these substances have been linked to various health issues and are notoriously persistent in the environment. But there’s no need to live in fear. The truth is, you can take control of your water quality and minimise your exposure to these chemicals.
So can PFAS be filtered out of water? Yes, one of the most effective ways to combat PFAS in your drinking water is by using a high-quality water filter. Filters that employ technologies such as activated carbon or reverse osmosis are particularly good at capturing these contaminants and ensuring that the water you drink is safe and clean.
How water filters can remove PFAS from water supplies
Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been used in industry and consumer products worldwide since the 1950s. They are often referred to as "forever chemicals" because they do not break down in the environment and can accumulate over time.
The presence of PFAS in drinking water has become a significant concern due to their potential health risks, including increased cholesterol levels, changes in liver enzymes, and increased risk of certain cancers. Here are the most common types of filtration technologies that can tackle PFAS:
1. Activated Carbon Filtration
This method uses a bed of activated carbon to remove contaminants through adsorption, where PFAS molecules bind to the surface of the carbon particles. Granulated activated carbon (GAC) and powdered activated carbon (PAC) are two forms used. While activated carbon is effective in removing many PFAS compounds, its performance can vary based on the specific PFAS present and the water's chemical composition.
2. Ion Exchange Resins
These resins are effective in removing charged substances from water, including some PFAS chemicals. Ion exchange systems use resins that exchange specific ions within the water with ions in the resin, trapping PFAS compounds. This method is particularly effective for shorter-chain PFAS, which are typically harder to remove.
3. Reverse Osmosis (RO)
This technology forces water through a semi-permeable membrane that blocks molecules larger than water, effectively removing PFAS. Reverse osmosis can remove a wide range of PFAS compounds, including those with longer chains that are typically more difficult to filter out using other methods

Factors influencing filter effectiveness
1. Type of PFAS
The chemical structure and chain length of PFAS impact how easily they can be removed. Longer-chain PFAS are generally more effectively removed by RO systems, while activated carbon and ion exchange may struggle with some variants.
2. Water Chemistry
The presence of other contaminants can affect filter performance. For example, high levels of organic matter can reduce the effectiveness of activated carbon filters.
3. Filter Maintenance
Regular replacement and maintenance of filter systems are crucial for sustaining their effectiveness in removing PFAS and other contaminants.
Other ways to get PFAS out of your drinking water
1. Use Bottled Water
For drinking and cooking, you might consider using bottled water that has been tested and verified to be free of PFAS. This can be an immediate solution, though it's not environmentally sustainable as a long-term option.
2. Check Local Water Reports
Stay informed about the PFAS levels in your local water supply by checking the annual water quality reports provided by your water utility. This can help you assess the necessity of taking further action.
3. Support and Follow Research
Stay updated on new research and emerging technologies for PFAS removal. Newer, more accessible solutions might become available that can be implemented on a smaller scale or at home.
4. Community Initiatives
Join or initiate community groups focused on clean water advocacy. These groups can be powerful in influencing policy and potentially funding community-level solutions like advanced filtration systems for local water supplies.
Frequently asked questions
Can a water filter remove PFAS?
Yes, specific types of water filters can remove PFAS from drinking water. Look for filters that use activated carbon or reverse osmosis, as these are effective at reducing PFAS levels. It's important to maintain the filter according to the manufacturer's instructions for best results.
Can PFAS be distilled out of water?
Yes, distillation can remove PFAS from water. This process involves boiling water to create steam, which then condenses back into liquid water. Since PFAS do not evaporate easily, they are left behind in the boiling process. However, distillation requires significant energy and time, making it less practical for large quantities of water.
Is it safe to drink rainwater with PFAS?
Drinking rainwater that contains PFAS is not recommended. While the concentration of PFAS in rainwater can vary, any detectable level poses a risk. PFAS are persistent chemicals that can accumulate in the body over time, potentially leading to health issues.
How do you remove PFAS from rainwater?
Removing PFAS from rainwater effectively can be challenging, but using a system that incorporates both activated carbon filters and reverse osmosis is one of the most effective methods. These systems can be set up to treat rainwater as it is collected, making sure that the water is safer for use.
What is the cheapest way to purify water?
The cheapest way to purify water typically involves using bleach or iodine tablets, which are effective against many pathogens but do not remove chemical contaminants like PFAS. For removing a wide range of contaminants including PFAS, a more comprehensive approach using a combination of sediment filters, activated carbon, and possibly reverse osmosis will be more effective, though these methods come at a higher initial cost.
