What filters PFAS from water

Today’s Quick Question is: What filters PFAS from water?

PFAS, short for per- and polyfluoroalkyl substances, are man-made chemicals that can be found in water supplies.

Fortunately, there are filters that can remove PFAS and make our water safer to drink.

Activated Carbon Filters

Activated carbon filters are effective in removing PFAS. These filters are made from a special material that attracts and traps the PFAS molecules as water passes through.

This process helps reduce the amount of PFAS in the water, making it cleaner and healthier for us to consume.

Activated Carbon Filters:

Ion Exchange Filters

Another type of filter that can remove PFAS is called an ion exchange filter. These filters work by exchanging ions with the PFAS molecules, effectively removing them from the water.

Ion exchange filters are often used in combination with activated carbon filters to provide even better filtration results.

PUR filters are also a good example of this.

Reverse Osmosis Filters

Reverse osmosis filters are also known for their ability to remove PFAS. These filters use a membrane to separate the water from the contaminants, including PFAS.

The membrane has tiny pores that only allow water molecules to pass through, while trapping the PFAS molecules and other impurities.

Note: Not all filters are capable of removing PFAS. When choosing a filter, look for those specifically designed for PFAS removal. Check the packaging or product information to see if the filter is certified to remove PFAS.

Replace Your Filters Regularly

Regular maintenance and filter replacement are crucial to ensure the effectiveness of PFAS removal.

Follow the manufacturer’s recommendations for replacing filters to maintain optimal filtration performance.

Additionally, remember to clean and maintain the filter system as instructed to prevent any buildup or clogging that could reduce its efficiency.


In conclusion, filters play a vital role in removing PFAS from our water.

Activated carbon filters, ion exchange filters, and reverse osmosis filters are effective in reducing PFAS levels.

However, it is important to choose filters that are specifically designed for PFAS removal and to follow proper maintenance and replacement guidelines.

By using the right filters and taking necessary precautions, we can enjoy cleaner and safer drinking water for a healthier lifestyle.
