Have you heard about PFAS in your drinking water? Per- and polyfluoroalkyl substances (PFAS) are a growing concern because of potential health effects linked to long-term exposure. While research is ongoing, some studies suggest connections to certain cancers and other health issues. The good news is you can take action! This guide explores effective techniques to remove PFAS from your home water supply, empowering you to safeguard your health and enjoy clean, worry-free water. Let’s dive into these filtration solutions and ensure every sip is a healthy one!

Activated Carbon Filters

It is common to use activated carbon filters for PFAS removal. They effectively trap contaminants as water passes through porous carbon particles. These filters can be installed in various forms, including pitcher filters, faucet attachments, and whole-house systems. While effective, it’s essential to regularly replace carbon filters to maintain their efficiency in capturing PFAS.

Reverse Osmosis Systems


Although initially more expensive than other filtration methods, Reverse Osmosis Systems provide superior water purification and long-term cost savings. It is capable of eliminating up to 99% of PFAS compounds and does so by essentially using a semi-permeable membrane.

Ion Exchange Resins

Ion exchange resins offer another efficient means of PFAS removal by exchanging harmful ions with less toxic counterparts. These resins attract and bind PFAS molecules, preventing them from passing through the purification system. While effective, ion exchange filters may require periodic regeneration or replacement to maintain optimal performance.

Granular Activated Carbon (GAC)


Similar to activated carbon filters, the granular activated carbon (GAC) process utilizes porous carbon particles to adsorb PFAS contaminants. GAC filters are commonly employed in point-of-entry and point-of-use systems, providing additional protection against harmful substances. Regular replacement of GAC media is necessary to ensure continuous PFAS removal.

Inspired from a natural rain cycle, distillation involves boiling the water and then capturing the clean vapor that condenses back into purified water. PFAS and other contaminants that are unable to vaporize are left behind. This method effectively removes PFAS, but it’s slower and uses more energy than some filters. Distillation also removes beneficial minerals, so consider remineralization for complete, healthy drinking water.



Nanofiltration employs specialized membranes with ultrafine pores to remove contaminants of varying sizes and charges. Although effective in removing PFAS, nanofiltration systems are relatively uncommon in residential settings due to their high cost and complexity. However, advancements in technology may make nanofiltration more accessible in the future.

Point-of-Use Vs. Point-of-Entry Filtration

When considering PFAS filtration options, deciding between point-of-use (POU) and point-of-entry (POE) systems is essential. POU filters, such as pitcher filters and faucet attachments, provide targeted purification at specific water outlets. At the same time, POE systems treat water at the main entry point into the home, ensuring comprehensive protection throughout the household.

Regular Maintenance and Monitoring

Regardless of the filtration method chosen, regular servicing and monitoring are essential for ensuring good water quality. Follow manufacturer guidelines for filter replacement or regeneration, and periodically test your water for PFAS and other contaminants to ensure the continued efficacy of your chosen system.

Professional Consultation


Consulting with a water quality professional is advisable for individuals concerned about PFAS contamination or seeking tailored water treatment solutions. The experts can advise you on the most suitable purification technologies and provide guidance on installation, maintenance, and monitoring to safeguard your drinking water effectively.
