Understanding PFAS and Why They Matter

Per- and polyfluoroalkyl substances (PFAS) are a large group of synthetic chemicals used in products for their resistance to heat, oil, water, and stains. Unfortunately, these same properties make them extremely persistent in the environment and in our bodies. PFAS have earned the nickname “forever chemicals” because they do not readily break down and can accumulate over time.

Health concerns linked to PFAS exposure include:

• Increased cholesterol levels

• Hormonal and thyroid disruption

• Immune system suppression

• Developmental issues in children

• Certain cancers

These risks have prompted global regulatory reviews and public calls for action.

PFAS in Sydney’s Tap Water

A recent UNSW Sydney study revealed that Sydney tap water contains more varieties of PFAS than previously detected. The findings suggest that contamination is more widespread and complex than earlier assessments indicated.

This research follows a growing number of international studies showing PFAS levels in surface and groundwater sources above safe drinking water limits.

Why Most Standard Filters Do Not Remove PFAS

While many households in Sydney already use water filters, most standard pitcher or tap-mounted filters are not designed to remove PFAS. This is because PFAS molecules are:

• Chemically resistant, making them hard to break down

• Small in size, allowing them to pass through ordinary filter media

• Water-repellent, making them less likely to bind to generic filter surfaces

Effective PFAS Removal Technologies

If you are shopping for a PFAS water filter, look for one that uses proven technologies such as:

1. Granular Activated Carbon (GAC)

   • Works by adsorbing PFAS onto carbon particles

   • Particularly effective for long-chain PFAS

   • Requires regular replacement to maintain effectiveness

2. Ion Exchange Resins

   • Uses positively charged resin beads to attract and bind negatively charged PFAS molecules

   • Often used in combination with GAC for better coverage

3. Reverse Osmosis (RO)

   • Forces water through a semi-permeable membrane to block PFAS and other contaminants

   • Removes up to 99% of PFAS

   • Ideal for households seeking maximum protection

Filpure Water Filters — Proven PFAS Protection

At Filpure Water Filtration Systems, we specialise in solutions that are not only effective against common tap water impurities but also capable of removing PFAS to help protect your health and well-being.

1. Filpure Whole House Water Filters
Our whole house filtration systems use advanced multi-stage technology, including high-grade activated carbon and sediment filtration, to target a broad range of contaminants, including PFAS. This ensures that every water outlet in your home—from the kitchen tap to the shower—is delivering cleaner, safer water.

2. Filpure Reverse Osmosis Systems
Our reverse osmosis systems are laboratory-tested to remove up to 99% of PFAS, along with heavy metals, chlorine, fluoride, and other pollutants. By using ultra-fine membranes combined with activated carbon polishing, we provide one of the most effective PFAS removal methods available for households.

Key Benefits of Choosing Filpure for PFAS Removal:

• Australian-made and built for local water conditions

• Certified components meeting WaterMark specifications

• Professional installation and maintenance by experienced technicians

• Tailored solutions for homes, offices, and commercial sites

By choosing a Filpure PFAS water filter, you can rest assured that you are taking a significant step towards keeping your family safe from harmful forever chemicals.

The Local Regulatory Landscape

Australia’s current drinking water guidelines for PFAS are less strict than those in countries like the United States. For example, the U.S. EPA has proposed limits as low as 4 ng/L for certain PFAS compounds, while Australian guidelines allow significantly higher levels.

With evidence mounting, regulatory updates are expected, meaning PFAS removal will become an even greater priority for water suppliers and consumers.
