PFAS (per- and polyfluoroalkyl substances) — often called “forever chemicals” — have made headlines for contaminating water supplies around the world, including in Australia. These man-made chemicals are used in everything from non-stick cookware to waterproof clothing, but their presence in drinking water is now a growing health concern.In this guide, we’ll explain how to remove PFAS from drinking water, why it matters for your health, and which PFAS water filters are proven to work. At Pure4Sure, we specialise in advanced water filtration systems designed to protect your home and family.

What Are PFAS and Why Should You Be Concerned?

PFAS are a large group of human-made chemicals used for decades in industries and consumer products due to their water- and oil-resistant properties. Unfortunately, these chemicals are highly persistent, meaning they stay in our environment — and our bodies — for many years.The biggest concern? PFAS contamination in drinking water. Even small amounts over time can build up in the body, increasing the risk of long-term health effects.

What Products Contain PFAS?

PFAS are present in many common items, including:

Non-stick cookware (like Teflon-coated pans)
Stain-resistant carpets and upholstery
Waterproof clothing
Fast-food packaging and takeaway containers
Firefighting foams
Cosmetics and personal care products

Because they’re so widely used, PFAS can easily enter our water supply through industrial waste, landfill runoff, and contaminated soil.

PFAS Health Effects to Humans

Research, including studies by the Environmental Working Group, has linked PFAS exposure to:

Hormonal disruption
Increased cholesterol levels
Immune system suppression
Thyroid disease
Certain types of cancer
Developmental delays in children

The fact that these chemicals can stay in the body for years makes early prevention critical.

What Can I Do About PFAS Chemicals Today?

You can’t remove PFAS from the environment on your own, but you can limit your personal exposure.
Some quick steps include:

Avoiding non-stick cookware and choosing stainless steel or cast iron.
Reducing the use of packaged fast food.

Installing a PFAS water filter at home.

The Australian Drinking Water Guidelines

The Australian Drinking Water Guidelines (ADWG) set safety limits for contaminants, including PFAS. However, many experts believe the current limits are still too high to fully protect human health. That’s why many Australian households are opting for reverse osmosis or activated carbon filtration to achieve safer levels.

PFAS Exposure in Australia

PFAS contamination has been detected in several regions, particularly near industrial sites and military bases where firefighting foam has been used. Even if you don’t live near one of these areas, PFAS can still travel through waterways and enter local water supplies.

What Water Filters Remove PFAS? 5 Proven Solutions for Safer Drinking Water

Not all water filters are effective against PFAS. Here are the top solutions backed by studies and industry research:

Activated Carbon Filters
Activated carbon traps PFAS molecules through a process called adsorption. These filters are ideal for reducing PFAS in tap water and are relatively affordable.
Granular Activated Carbon (GAC) Filters
Similar to activated carbon, but with larger granules that allow longer contact time with water. This makes them more effective for PFAS removal over time.
Reverse Osmosis (RO) Systems
Considered one of the most effective PFAS water filters, RO systems use a semipermeable membrane to remove up to 99% of contaminants, including PFAS, heavy metals, and other chemicals.
Ion Exchange Filters
These filters replace harmful PFAS ions with harmless ones. They are commonly used in combination with carbon filters for maximum efficiency.
Multi-Stage Filtration Systems
Combining activated carbon, reverse osmosis, and sediment filters, these systems offer comprehensive water treatment for households looking for long-term PFAS removal.

How to Choose the Right PFAS Water Filter for Your Home

When choosing a PFAS water filter, it’s important to focus on solutions that are certified and proven effective. Look for systems that use reverse osmosis, activated carbon, or a combination of both for the best results.

Frequently Asked Questions (FAQs) about PFAS and Water Filtration

What are PFAS in drinking water?

PFAS, or per- and polyfluoroalkyl substances, are a group of synthetic chemicals used in non-stick cookware, waterproof fabrics, and food packaging. They are called “forever chemicals” because they don’t break down easily and can remain in water, soil, and the human body for decades.

Are PFAS harmful to human health?

Yes. According to the PFAS health effects page from the EPA, PFAS exposure may increase the risk of cancer, disrupt hormones, weaken the immune system, and cause developmental delays in children. Long-term exposure, even at low levels, is considered a public health concern.

How do I know if my water contains PFAS?

You can:

Use a home water testing kit for PFAS.
Request a water quality report from your local supplier.

Do all water filters remove PFAS?

No. Only certain filters, like activated carbon, granular activated carbon (GAC), reverse osmosis (RO), and ion exchange filters are proven to reduce PFAS levels. Look for systems certified to NSF/ANSI 53 or 58, as recommended in the EPA guidance on PFAS water filters.

What is the most effective water filter for PFAS removal?

A Reverse Osmosis (RO) system is considered the most effective, often eliminating up to 99% of PFAS from drinking water. Other effective options include:

Activated Carbon Filters
Granular Activated Carbon (GAC) Filters
Ion Exchange Filters
Multi-Stage Filtration Systems

Pure4Sure offers certified RO and multi-stage filtration systems designed for long-term PFAS removal at home.

Can boiling water remove PFAS?

No. PFAS do not evaporate or break down with heat, so boiling water will not remove them. You need a certified PFAS water filter for effective removal.

Is PFAS contamination a problem in Australia?

Yes. PFAS exposure in Australia has been documented in areas near military bases, airports, and industrial zones due to historical firefighting foam use. Even if you don’t live in a high-risk area, contamination can travel through waterways, so filtration is still recommended.
