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.
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.
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:
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.
PFAS enter city water systems through industrial pollution, landfill leachate, and wastewater treatment plant discharges.
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.
Yes, but only specific water filtration systems, such as activated carbon, ion exchange, and reverse osmosis systems, are effective at reducing PFAS levels.
To effectively remove PFAS, you need systems that use proven technologies like:
The Pioneer POE filter system stands out among whole-house filtration systems as one of the best solutions for comprehensive home protection against PFAS. It offers changeable cartridges for effective, large-scale water treatment.
This Pioneer System uses a certified filtration media that targets PFAS, lead, and cysts at the point-of-entry, protecting your entire home’s water supply.
Yes, the PFAS High Capacity Removal Filter System uses advanced ResinTech resin media that provides an extended filter life, lasting up to 10 times longer than traditional activated carbon systems.
This PFAS High Capacity Removal Filter leverages a high-performance SIR-110-HP ion exchange resin that outperforms carbon filters in both longevity and efficiency. Unlike traditional systems, it requires no backwashing, regeneration, or frequent media changes.
With fewer replacements and higher efficiency, this system is a cost-effective, eco-friendly alternative for long-term PFAS protection. It uses certified filters that have undergone independent testing to ensure effective removal of PFAS and other contaminants.
An under sink water filter, specifically a high-flow reverse osmosis system, is ideal for PFAS removal at the tap.
This 4-stage RO system uses four distinct filtration stages, combining carbon and membrane filtration to strip PFAS, fluoride, and other harmful chemicals, delivering crisp, clean water directly from your kitchen sink.
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.
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.
Filter replacements are typically needed every 6–12 months for under-sink filters and annually for whole-house systems.
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.
You can check your local water quality report or collect a water sample and send it to a certified lab for PFAS testing.
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.
Yes, the Environmental Protection Agency (EPA) recently set enforceable limits for six PFAS compounds in drinking water under the Safe Drinking Water Act.
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.
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.
If you’re handy with basic plumbing tools, an under-sink or countertop reverse osmosis system is an easy weekend project for PFAS removal. For POE systems, a plumber ensures proper sizing and compliance with local building codes.
You can buy tested and proven PFAS filters online at reputable sites like Clean Water Store.
Explore filters specifically designed for PFAS at Clean Water Store. Their systems meet certification standards and are supported by expert staff who can guide your selection.
For those seeking a portable solution, products like the Clearly Filtered Water Pitcher are also available and offer certified PFAS removal.

Complete Guide to Whole House Water Filtration for City Water
No, boiling does not remove PFAS and may actually concentrate them.
Most Brita filters are not certified to remove PFAS.
Under-sink systems range from $200–$600, while whole house filters can cost $800–$2000+. Some expensive filters may offer additional features, but they are not always more effective at removing PFAS.
Not necessarily—some bottled water also contains PFAS; check labels or third-party tests. High-quality filters can provide delicious water by removing PFAS and other taste-affecting contaminants.
Distillers may remove some PFAS, but they are not consistently effective, especially for short-chain PFAS compounds. Other filters designed specifically for PFAS removal, such as activated carbon or reverse osmosis systems, are often more effective and reliable for targeting these contaminants.
A: Pairing carbon filters with a distiller can significantly improve PFAS removal, offering broader protection across both long and short-chain PFAS. By combining these filtration methods, you can remove as many contaminants as possible, including PFAS.
Most built-in fridge filters are not designed to remove PFAS. Under-sink water filters are generally more effective at treating sink water for PFAS removal, as they filter water directly at the point of use and can reduce contaminants like PFAS, lead, and chlorine to provide safer, better-tasting tap water.
