Best Water Filter System for PFAS in City Water
PFAS chemicals in city water are a growing concern—and for good reason. These harmful contaminants are linked to serious health issues, and many municipal water systems aren't equipped to remove them.
If you want to protect your household, finding the best water filter system for PFAS in city water is a smart and necessary move. Let's break down your top options in a clear, practical way.
What are PFAS, and Why are They Dangerous?
PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals that don't break down easily and have been linked to cancer, immune system damage, and hormone disruption.
Understanding the Health Risks of PFAS
PFAS are commonly found in firefighting foam, non-stick cookware, and water-resistant materials. They enter water supplies through industrial runoff and wastewater and accumulate in the human body over time, leading to severe health conditions such as:
- Kidney and testicular cancers
- Increased cholesterol levels
- Weakened immune system
- Hormonal disruption
PFAS exposure poses a significant threat to human health, as these chemicals have been linked to a broad range of health concerns, including cancer, thyroid disease, and immune disorders.
How do PFAS Get Into City Water?
PFAS enter city water systems through industrial pollution, landfill leachate, and wastewater treatment plant discharges.
Sources of PFAS Contamination
City water can become contaminated with PFAS due to nearby manufacturing facilities, military bases using firefighting foam, waste disposal sites, or the discharge of wastewater containing PFAS. Once in the environment, PFAS persist and migrate into surface and groundwater supplies used for municipal treatment.
Can city water filters remove PFAS?
Yes, but only specific water filtration systems, such as activated carbon, ion exchange, and reverse osmosis systems, are effective at reducing PFAS levels.
Not All Filters Are Created Equal
To effectively remove PFAS, you need systems that use proven technologies like:
- Activated Carbon (GAC): Uses granular activated carbon to absorb PFAS compounds from water
- Ion Exchange Resins: Swap PFAS for harmless ions
- Reverse Osmosis: Filters PFAS through semipermeable membranes

Are There Filters that Combine Lead and PFAS Removal?
Yes, only filters certified for both lead and PFAS removal, such as the Pioneer system and other advanced carbon block filters, should be considered for dual protection.
Dual Protection Is Essential
Many homes face contamination from both lead pipes and PFAS. Choosing a dual-certified system like the Pioneer POE filter offers comprehensive protection for your family’s health and drinking water quality, while also providing defense against other contaminants commonly found in city water.
How Often Should PFAS Filters be Replaced?
Filter replacements are typically needed every 6–12 months for under-sink filters and annually for whole-house systems.
Maintenance Matters
Proper maintenance ensures your filter continues to block PFAS effectively. Systems that require frequent filter changes may have higher ongoing maintenance costs, so consider filter durability and efficiency when choosing a solution. Always follow the manufacturer’s guidelines for replacement timelines and monitor flow rate changes or water quality for signs of filter exhaustion.
How do I know if PFAS are in my city water?
You can check your local water quality report or collect a water sample and send it to a certified lab for PFAS testing.
Get the Facts on Your Tap Water
Start with your municipality’s Consumer Confidence Report (CCR), usually available on their website. For peace of mind, a laboratory test tailored to PFAS detection is highly recommended. Many labs offer mail-in kits for convenience.
The results of your water test can guide you in selecting the most effective drinking water treatment systems for PFAS removal.
Are PFAS Regulations Enforced in the U.S.?
Yes, the Environmental Protection Agency (EPA) recently set enforceable limits for six PFAS compounds in drinking water under the Safe Drinking Water Act.
EPA PFAS Regulation in 2024
In April 2024, the EPA finalized a national drinking water standard for PFAS, targeting PFOA and PFOS at 4 parts per trillion (ppt). This move aims to reduce long-term exposure, though municipal compliance may take time.
Can I install a PFAS water filter myself?
The setup process for under-sink and countertop PFAS filters is generally straightforward and suitable for DIY installation, but whole-house systems may require professional help.
