Among many industrial chemicals that harm water channels, the PFAS group, also called “forever chemicals,” is a harmful group. These chemical substances have been found in water resources and supplied worldwide, raising questions about our water filters' effectiveness and purity of our water channels.
Understanding the causes and removal tactics of PFAS can significantly help you safeguard your health. This article explains what PFAS are and how to effectively eliminate them to ensure safe water for your family.
What is Forever Chemicals?
PFAS are pre- and poly-fluoroalkyl substances, comprising a large group of artificial and human-made industrial and consumer product waste chemicals since the 1940s. PFAS are primarily found in water-repellent clothing, non-stick cookware, firefighting foam, and food packaging.
These chemicals are water, oil, heat, and stain-resistant, making them crucial for manufacturing. As a result, they are stubborn and persistent in the environment which makes them extremely harmful for humans and other living beings.
Do Water Filters Remove Forever Chemicals?
Not all water filters are capable of removing PFAS from drinking water. However, some types of filters have been proven effective in reducing or eliminating PFAS contamination:
- Activated Carbon Filters: Granular activated carbon (GAC) filters are one of the most effective methods for removing PFAS. These filters work by adsorbing PFAS molecules onto the surface of the carbon. However, the effectiveness of GAC filters can vary depending on the specific PFAS compounds and their concentration levels.
- Reverse Osmosis Systems: Reverse osmosis (RO) systems are highly effective at removing many contaminants, including PFAS. These systems force water through a semipermeable membrane, trapping contaminants and allowing only clean water to pass through.
- Ion Exchange Filters: Ion exchange systems can also remove PFAS by replacing the harmful ions with harmless ones. These systems are particularly effective at removing shorter-chain PFAS compounds.
While these filtration methods can significantly reduce PFAS levels, it is essential to choose a filter certified to remove PFAS. Certification by independent testing organizations, such as NSF International, ensures that the filter meets specific standards for contaminant removal.
Here are some other common signs that indicate low water resource quality and if you need a water filter.
Choosing the Right Water Filter for PFAS
When selecting a water filter to remove PFAS, consider the following:
- Certification: Look for filters that have an NSF standard for PFAS removal. This certification guarantees that the filter has been tested and proven effective.
- Filter Type: Depending on your needs, choose between activated carbon filters, reverse osmosis systems, or ion exchange filters. Each has advantages and may be more suitable depending on the PFAS levels in your water.
- Maintenance: Regular maintenance is crucial for ensuring the continued effectiveness of your water filter. To maintain optimal performance, follow the manufacturer's recommendations for filter replacement.
- Water Testing: Before and after installing a water filter, consider having your water tested for PFAS. This will help you determine the filter's effectiveness and whether further action is needed.

How to Remove PFAS from Water - Additional Steps
In addition to using an effective water filter, consider these steps to reduce your exposure to PFAS:
- Avoid Non-Stick Cookware: Replace non-stick cookware with alternatives like stainless steel or cast iron.
- Check Product Labels: Avoid products labeled as water-repellent, stain-resistant, or grease-resistant, as these may contain PFAS.
- Stay Informed: Keep updated with information from your local water supplier and public health agencies regarding PFAS contamination and recommended actions.
Conclusion
PFAS, or "forever chemicals," are a growing concern due to their persistence in the environment and potential health risks. While not all water filters can remove PFAS, activated carbon filters, reverse osmosis systems, and ion exchange filters can effectively reduce or eliminate these harmful substances from drinking water. By choosing the right filter and taking additional steps to reduce exposure, you can protect yourself and your family from the potential dangers of PFAS.
