Yes. Melbourne’s drinking water has been fluoridated since 1977, and the level is set by Victorian law rather than by your water retailer. If you have landed here, you probably want two things: the actual number, and a straight answer on whether a filter takes it out.
Both are below. The short version is that the level is low and tightly controlled; the health authorities are clear that it is safe at that level; and if you nonetheless want it out of your drinking water, most filters will not do it and one type will.
How Much Fluoride Is Actually in Melbourne’s Water
Fluoridation in Victoria is regulated under the Health (Fluoridation) Act 1973. Melbourne Water doses at the treatment plants, and the three retailers, Yarra Valley Water, South East Water and Greater Western Water, distribute the treated supply.
Victoria’s target is around 1 milligram per litre, which is the same as 1 part per million. Yarra Valley Water describes an acceptable range of roughly 0.7 to 1.2 mg/L with an optimum close to 0.9. Reported figures across Melbourne’s supply zones generally sit between 0.7 and 1.0.
For scale, a milligram per litre is a very small quantity. Yarra Valley Water puts it at roughly the equivalent of a single grain of sugar in a cup of water. Levels are monitored continuously at the plants, and dosing equipment is designed to shut down if the concentration moves outside its set limits.
Worth knowing: a small amount of fluoride occurs naturally in water anyway. Fluoridation adjusts that natural level up to the target rather than introducing something that was not there at all.
What the Health Authorities Actually Say
We install water filters for a living, so it is worth being straight about this rather than selling against it.
The National Health and Medical Research Council, in its 2017 public statement, strongly recommends community water fluoridation as a safe, effective and ethical way to reduce tooth decay, and supports fluoridation within a range of 0.6 to 1.1 mg/L. The Australian Drinking Water Guidelines set a health-based guideline value of 1.5 mg/L, which is well above the level Melbourne doses at. That position is shared by the World Health Organisation and the Australian Dental Association.
So if your question is whether Melbourne’s tap water is safe to drink as supplied, the answer from every relevant authority is yes.
Some households still prefer to remove it. Reasons vary, from a preference for the least-processed drinking water possible, through to households already getting fluoride from other sources, through to simple personal choice. That is a legitimate preference, and it is not our business to talk anyone into or out of it. What we can tell you accurately is what will and will not remove it, because that is a technical question with a clear answer, and it is the one most people get wrong.
What Does Not Remove Fluoride
This is where most money gets wasted, because the filters people reach for first are the ones that do nothing here.
- Jug filters and tap-mounted filters. These are carbon-based. Carbon works by adsorption, which is very effective on chlorine, taste, odour and a wide range of organic chemicals. Fluoride is a small dissolved ion, and carbon does not hold onto it.
- Standard whole-house carbon filters. Same chemistry, much larger scale. A whole-house filter is genuinely good at what it does, treating every tap, shower and appliance for chlorine, sediment and chemicals. Removing fluoride is simply not one of the things it does.
- Boiling the water. This one is worth stating plainly because it is a common assumption,n and it is backwards. Boiling evaporates water and leaves dissolved minerals behind, so the fluoride concentration in what remains goes slightly up, not down.
- Letting water stand. Chlorine will off-gas if water sits uncovered. Fluoride will not. It is a dissolved salt, not a dissolved gas.
The Mistake We See Most Often
Someone installs a whole-house carbon filter specifically to remove fluoride, and it does not, because that is not what carbon does. The filter itself is working perfectly and doing a genuinely useful job on chlorine and sediment. It was just bought for the wrong reason. If fluoride is your reason for filtering, say so before you buy anything, because it changes which system you need.
What Removes Fluoride
Reverse osmosis. It is the practical option for a household, and the reason is the mechanism rather than the brand.
Rather than adsorbing contaminants onto a surface, reverse osmosis pushes water under pressure through a membrane with openings so fine that essentially only water molecules pass. Dissolved ions, fluoride among them, are too large to get through and are flushed away. That is why RO removes a broad range of dissolved contaminants rather than a specific list, and why it is the one residential technology that handles fluoride properly.
| Filter Type | Removes Fluoride? | What It Is Actually Good At |
|---|---|---|
| Jug or tap-mounted carbon filter | No | Chlorine taste and odour, at low cost and with no installation |
| Whole-house carbon filter | No | Chlorine, sediment and chemicals at every tap, shower and appliance in the house |
| Under-sink reverse osmosis | Yes | Fluoride, dissolved solids, heavy metals and a broad range of dissolved contaminants, at one dedicated drinking tap |
| Boiling | No, slightly concentrates it | Killing microorganisms, which is not a concern on Melbourne’s treated supply |
The trade-off worth understanding before committing: RO treats one tap rather than the whole house; it works more slowly than a carbon filter because the membrane is doing far more, and it sends some water to waste as part of the process. It also removes beneficial dissolved minerals along with everything else, which is why many systems add a remineralising stage. We set all of that out, including the downsides, in ” Is reverse osmosis worth it.

Do You Need a Whole-House Filter as Well?
They solve different problems, which is the thing most comparison articles blur.
A whole-house carbon filter sits on the main line and treats every drop entering the house, so it deals with chlorine taste in the shower, sediment reaching appliances, and chemicals at every tap. An under-sink RO system treats a single dedicated drinking tap to a far higher standard.
If your concern is fluoride and dissolved contaminants in what you drink and cook with, RO on its own answers it. If your concern is chlorine smell in the shower or sediment in the washing machine, RO does nothing for that, and a whole-house filter is what you want. Plenty of households end up with both, for those two different reasons. Our reverse osmosis versus carbon filter comparison goes through it properly.
If you are in an apartment, a whole-house filter is usually not an option at all, because it needs a connection to the main line, and that is shared building infrastructure. An under-sink system connects only to your own plumbing under the kitchen sink, which is why it is the realistic choice there. We cover that in water filters for apartments and units.
Frequently Asked Questions
Does Melbourne tap water have fluoride in it?
Yes. Melbourne’s supply has been fluoridated since 1977 under the Victorian Health (Fluoridation) Act 1973. Melbourne Water doses at the treatment plants,s and the level is monitored continuously, with Victoria targeting around 1 milligram per litre.
Is the fluoride level in Melbourne water safe?
The NHMRC strongly recommends community water fluoridation as safe and effective and supports fluoridation between 0.6 and 1.1 mg/L, which is the range Melbourne sits in. The Australian Drinking Water Guidelines set a health-based guideline value of 1.5 mg/L, well above what is dosed here. Whether you choose to drink it as supplied is a personal decision, but the health position is not in dispute among Australian authorities.
Will a jug filter or a fridge filter remove fluoride?
No. Those are carbon filters, which work by adsorption and are very good at removing chlorine, taste and odour. Fluoride is a small dissolved ion that carbon does not capture. If a product claims otherwise, ask specifically what technology it uses and what independent testing supports the claim.
Does boiling water remove fluoride?
No, and it does the opposite of what people expect. Boiling evaporates water while leaving dissolved minerals behind, so the concentration of fluoride in the remaining water goes slightly up rather than down.
Does reverse osmosis remove all the fluoride?
It removes the large majority of it, along with most other dissolved solids, which is the nature of the membrane rather than a fluoride-specific feature. No residential system is absolute, and performance depends on the membrane’s condition and water pressure, which is why cartridges and membranes have replacement intervals worth keeping to.
If I remove fluoride, should I do anything about dental health?
Worth a conversation with your dentist rather than with your plumber. Fluoridated water is one source of fluoride among several, including toothpaste, and a dentist can tell you whether anything changes for your household. We can tell you what the system does to the water. We are not the right people to advise on teeth.
Filtered Drinking Water, Installed Properly
We install under-sink reverse osmosis systems and whole-house filters across Melbourne as licensed plumbers, which matters because both involve connecting to your water supply and, for RO, to the drain as well. Tell us what you are trying to achieve, and we will tell you which one actually does it. See our full range of water filter services.
