How to Remove PFAS from Your Drinking Water: A Guide to Home Filtration

do home water filters remove pfas

In recent years, concerns about harmful chemicals in our drinking water have grown across Australia — and few are more alarming than PFAS. Known as “forever chemicals” due to their persistence in the environment, PFAS compounds have been linked to a variety of health risks. This guide explores how to remove PFAS from your drinking water at home, the best water filtration options available, and how to protect your household from exposure.

What Are PFAS and Why Are They a Problem?

PFAS, or per- and polyfluoroalkyl substances, are a group of human-made chemicals used in products like non-stick cookware, water-repellent fabrics, food packaging, and firefighting foam. Because of their strong chemical bonds, they don’t break down easily — meaning they accumulate over time in the environment and our bodies.

In Australia, PFAS contamination has been identified in several communities, particularly near military bases and industrial sites. Long-term exposure has been associated with health effects such as:

Hormonal disruption
Immune system suppression
Developmental issues in children
Increased risk of certain cancers

Can PFAS Be Filtered Out of Water?

Yes — but not all home water filters are created equal.

When asking do home water filters remove PFAS, the answer depends on the type and quality of the filtration system. Many basic filters, such as standard pitcher or tap filters, do not effectively reduce PFAS levels. For reliable protection, you’ll need a certified system designed specifically for chemical contaminant removal.

Types of Water Filters That Remove PFAS

Here are the main types of PFAS water filters that are proven to reduce or eliminate these contaminants:

1. Activated Carbon Filters (Granular and Block)

These filters use porous carbon to trap PFAS molecules. Block carbon filters tend to be more effective than granular ones due to a higher surface area.

Pros: Affordable, widely available
Cons: Must be replaced regularly for continued effectiveness

2. Reverse Osmosis Systems

RO systems force water through a semi-permeable membrane, removing a wide range of pollutants including PFAS.

Pros: Highly effective; removes up to 99% of contaminants
Cons: Slower flow rate; more expensive; typically requires professional installation

3. Ion Exchange Filters

These filters replace PFAS ions with harmless ions using a special resin.

Pros: Effective against long- and short-chain PFAS
Cons: Less common for home use; may require maintenance expertise

How to Remove PFAS from Water at Home

If you're wondering how to remove PFAS from water at home, follow these steps:

Step 1: Check Your Local Water Quality

Find out whether your area has known PFAS contamination. Australian state and territory governments, as well as local councils, often publish water quality reports.

Step 2: Choose a Certified Filter

Look for filters certified to remove PFAS — such as those with NSF/ANSI Standard 53 or 58 certification. These are tested for contaminant reduction, including PFOA and PFOS, the most common PFAS variants.

Step 3: Install Your Filter System

Decide on the best location and type for your needs:

Under-sink filters: Ideal for kitchens; easy access to safe drinking water
Benchtop units: Simple to install and maintain
Whole-house systems: Provide protection at every tap, including showers and laundry

Step 4: Maintain and Replace Your Filters

No matter how advanced your system is, it won’t work properly without routine maintenance. Always follow the manufacturer’s guidelines for replacing cartridges or membranes.

Best Practices and Additional Tips

Test your water periodically with at-home test kits or through a certified lab.
Keep up to date with local PFAS advisories and government updates.
Ensure your filter’s specifications mention PFAS or PFOA/PFOS specifically.
Don’t rely on boiling — it won’t remove PFAS and may concentrate them.

Conclusion: Protecting Your Home from PFAS Starts with Informed Choices

While PFAS contamination is a serious issue, it's one you can manage with the right tools and knowledge. By investing in a reliable PFAS water filter, you take a critical step toward ensuring your family's safety and long-term health.
