Fluoride and PFAS are two of the most searched water quality concerns in Australia — and for good reason. Fluoride is deliberately added to most Australian capital city water supplies. PFAS contamination has been identified at over 700 sites across the country. What trips people up is the water filter industry’s inconsistent labelling: products that “improve taste and reduce contaminants” are routinely marketed alongside products that actually remove fluoride and PFAS to measurable, verified degrees. This guide cuts through the noise with actual removal rate data, filter by filter.

What Are Fluoride and PFAS — and Why Are They in Australian Tap Water?

Fluoride is added to drinking water by most Australian state water authorities at concentrations of 0.6–1.0mg/L under the Australian Drinking Water Guidelines. The stated rationale is dental health. Fluoride is added to tap water in NSW (Sydney Water), VIC (Melbourne Water), QLD (Urban Utilities, Unitywater), SA (SA Water), and WA (Water Corporation). The Northern Territory, most of Tasmania, and many regional areas do not fluoridate. Check what’s in your state’s tap water to confirm whether your supply is fluoridated.

PFAS (per- and polyfluoroalkyl substances) are a group of over 12,000 synthetic chemicals used in firefighting foam (AFFF), non-stick cookware coatings, food packaging and industrial processes. They don’t break down in the environment or in the human body — hence “forever chemicals.” The Australian Government has identified over 700 sites with confirmed or potential PFAS contamination, concentrated around defence bases, airports, and industrial zones. The NHMRC’s Australian Drinking Water Guidelines set provisional guidance values of 0.56 µg/L for PFOA and 0.07 µg/L for PFOS — however, emerging science suggests these limits may still be too high for long-term safety.

Which Filter Technologies Actually Remove Fluoride and PFAS?

The short answer: reverse osmosis removes both effectively. Gravity filters with specific add-on media remove both. Standard activated carbon removes neither to a meaningful degree. Pitcher filters remove neither.

Here’s why: fluoride is a dissolved ionic compound. Removing it requires either a semi-permeable membrane (RO), specific ion-exchange media (like the alumina-based media in Berkey’s PF-2 filters), or bone char carbon. Standard activated carbon adsorbs organic compounds and chlorine through chemical attraction — it doesn’t capture dissolved inorganic ions like fluoride.

PFAS removal follows a similar principle. PFAS molecules are large enough that RO membranes block them physically. Activated carbon can adsorb some PFAS compounds, but standard granular activated carbon (GAC) is inconsistent — longer chain PFAS compounds are captured more effectively than shorter chain ones. High-density carbon block or specific PFAS-targeted filter media performs significantly better than standard GAC.

Filter Type	Fluoride Removal	PFAS Removal	Chloramine	Lead	How It Works
Reverse Osmosis (Under-Sink)	Up to 96%	Up to 98%	Yes	Up to 99%	Membrane physical exclusion
Countertop RO (AquaTru)	Up to 96%	Up to 97%	Yes	Up to 99%	RO membrane, NSF 58 certified
Gravity Filter + PF-2 (Berkey)	Up to 99%	Up to 99%	Yes	Up to 99%	Alumina media + carbon block
Gravity Filter (Berkey, no PF-2)	❌ Not removed	Up to 99%	Yes	Up to 99%	Carbon block only
Clearly Filtered Pitcher	Up to 99.5%	Up to 99.9%	Yes	Up to 99%	Affinity filtration media
Tap Filter (Tappwater EcoPro)	~70%	93%	Yes	Yes	Multi-stage block carbon + KDF

Best Water Filters for Fluoride Removal Australia 2026

1. AquaTru Countertop RO — The most convenient way to remove fluoride without any plumbing. NSF/ANSI 58 certified for PFOA and PFOS reduction. Removes 96% fluoride in independent testing. Sits on your benchtop, no installation. Best for renters, apartment dwellers and those who don’t want to modify their plumbing. Price: approximately $450–550 AUD.

2. Berkey Royal + PF-2 Fluoride Filters — The classic gravity-fed solution. The Black Berkey carbon elements handle everything else (chloramine, PFAS, heavy metals, pathogens); the PF-2 fluoride elements add specific fluoride and arsenic removal. Important: the PF-2 filters must be installed — a standard Berkey without them does NOT remove fluoride, despite what some online sources claim. PF-2 filters cost approximately $60–80 AUD per pair and last 1,100 litres. See how reverse osmosis removes PFAS and fluoride for comparison.

3. Clearly Filtered Water Pitcher — NSF certified under Standards 42, 53, 244, 401, and 473. Removes fluoride to 99.5% and PFAS to 99.9% in certified testing. Easier to use than a Berkey — pour and go. Higher cost per litre than gravity or RO systems ($0.13–0.15/L) but no installation required.

Best Water Filters for PFAS Removal Australia 2026

For PFAS specifically, reverse osmosis is the gold standard. The AquaTru is NSF certified for PFOA and PFOS removal. Under-sink RO systems (Waterdrop D6, Frizzlife, standard 5-stage systems) all achieve comparable PFAS removal once the RO membrane is correctly specified.

For a no-plumbing PFAS solution, Tappwater EcoPro removes 93% of PFAS and is specifically lab-tested against Australian water — meaningful given that Australian PFAS contamination profiles (military base AFFF foam compounds) can differ from US profiles that some imported filter certifications are based on.

Important: Filters That Do NOT Remove Fluoride (Don’t Get Caught Out)

Several filter types are widely bought in Australia specifically because people believe they remove fluoride — and they don’t. Be clear-eyed about this before purchasing:

Berkey without PF-2 filters: A standard Berkey (Royal, Big Berkey, Travel Berkey) with only Black Berkey elements installed does not remove fluoride. Berkey’s own documentation confirms this. You must specifically add PF-2 polishing filters. Many Berkeys in Australian homes are running without them because the fluoride filters are sold separately and the distinction is easy to miss.

Standard pitcher filters (Brita, Pur): Granular activated carbon. Does not remove fluoride or PFAS. Improves taste and reduces some chlorine. The Brita website is transparent about this — the confusion comes from marketing language around “filtering” that doesn’t specify which contaminants.

Most tap-mount carbon filters: The exception is Tappwater EcoPro (70% fluoride reduction) and a handful of other advanced tap filters. Standard carbon tap mounts — including many sold in Bunnings and supermarkets — do not remove fluoride.

Whole house carbon filters: Unless specifically configured with an RO stage or fluoride-removal media, whole house filters are designed for chloramine, sediment and taste — not fluoride.

Frequently Asked Questions

Does boiling water remove fluoride?

No. Boiling actually concentrates fluoride — as water evaporates as steam, the fluoride (which doesn’t evaporate) becomes more concentrated in the remaining water. Only mechanical filtration (RO, specific media) removes fluoride from water.

Is fluoride in Australian tap water dangerous?

The Australian Drinking Water Guidelines consider fluoride safe at the levels added (0.6–1.0mg/L). Whether you want to remove it is a personal health decision. People who choose to filter fluoride typically do so for one or more of the following reasons: they have thyroid conditions (fluoride can compete with iodine uptake), they want to limit their family’s total fluoride exposure across all sources, or they simply prefer not to consume an added substance they didn’t choose. None of these positions is unreasonable.

How do I know if my tap water has PFAS contamination?

The Australian Department of Defence publishes a PFAS site register. Your state water authority should also be able to advise on current PFAS testing results for your supply zone. If you’re in a regional area near a defence base, airport, or former industrial site, it’s worth checking — some supplies have had temporary or ongoing elevated PFAS levels.

Do water softeners remove PFAS or fluoride?

Standard ion-exchange water softeners (which replace calcium/magnesium with sodium) do not remove PFAS or fluoride. Some specialist anion exchange resins can target PFAS, but these are industrial-scale systems rather than residential products. For household PFAS removal, RO remains the practical solution.

How much does it cost per day to have filtered water?

For a reverse osmosis system producing 4 litres per day of drinking water for a family: filter replacement costs average $120–180 AUD per year, or approximately $0.35–0.50 per day. At $0.05 per litre for 4 litres per day — dramatically cheaper than bottled water at $1–2 per litre.
