The science
Your water has been treated. Not purified.
Australian tap water meets the Australian Drinking Water Guidelines. But "compliant" does not mean "pure" — guidelines set legal limits, not zero. Here is what the science actually says, and how OzFlow's multi-barrier filtration responds.

Features & functions
Engineered for your tap
Designed to fit seamlessly onto what you already have — and make every glass taste the way water should.
Installs in 30 seconds
No tools, no plumber, no tank under the sink. OzFlow fits 99% of standard Australian taps and three adaptors are included in every box.
Advanced filtration
6 barriers. 6 mechanisms. One cartridge.
Each contaminant type needs a different technology. Activated carbon alone cannot reduce heavy metals. KDF media does not capture fluoride. That is why OzFlow combines six complementary mechanisms in a single cartridge.
Size exclusion — rust flakes, sand, pipe scale and suspended sediment are physically too large to pass through the fibre matrix. Water and dissolved minerals pass straight through.
Media: Non-woven fibreAvg. reduction 99%Chlorine, chloramine, THMs, volatile organic compounds and the odours that ruin tea and coffee bond to the enormous internal surface area of the carbon block.
Media: Coconut shell carbonAvg. reduction 98–99%A redox reaction converts free chlorine into harmless chloride and reduces dissolved heavy metals into insoluble forms that are captured downstream.
Media: KDF-55 Cu/Zn alloyAvg. reduction 95–99%Granular activated carbon engineered specifically for long and short-chain PFAS. The EPA lists GAC among its Best Available Technologies for PFAS removal.
Media: Modified GACAvg. reduction up to 99%A second, dedicated pass for lead, cadmium, mercury and copper, catching what redox media alone leaves behind at Australian flow rates.
Media: Ion-exchange resinAvg. reduction 95–99%A mineral adsorbent that captures fluoride ions while deliberately leaving calcium and magnesium in the water, so it still tastes like water.

Total PFAS
(NSF/ANSI 53)
Forever chemicals (PFAS/PFOS) build up in the body and never break down. They are present in most tap water supplies.
Avg. reduction99%Microplastics
(NSF/ANSI 401)
Microplastics are increasingly found in tap water. They now show up in human blood, placentas and brain tissue.
Avg. reduction100%Lead
(NSF/ANSI 53)
There is no safe level of lead exposure, especially for children and developing brains. Older plumbing is the usual source.

(NSF/ANSI 401)
Estrone enters the water supply from human and animal waste and can disrupt normal hormone function.

The chlorine smell is completely gone
Clamped onto the kitchen mixer in about three minutes, no plumber needed. Sits neatly beside the spout and the brushed finish matches our tapware. Our water used to smell like a swimming pool in summer — now the kids actually drink water instead of asking for cordial. Coffee tastes noticeably better too.

My hair stopped falling out in the shower
I was sceptical about a shower filter but the difference in week one was obvious. Less frizz, my scalp is not itchy and the pressure is genuinely stronger than the old head. Installed it myself in under a minute — it just screws in above the rain head.

Look at what came out of our water in one month
Pulled the first cartridge after a month and honestly it was confronting — the mesh had gone from bright silver to rusty brown. That is what we were drinking before. The subscription means I never have to think about ordering again.

We have stopped buying bottled water entirely
We were spending close to $40 a fortnight on bottled water for the office and home. This paid for itself in about two months and the water is clearly cleaner. Flow is strong enough to fill a jug without waiting around. Delivery was three days to WA.

The bundle is a no-brainer
Bought the whole home bundle. Packaging was tidy, everything was there, and both units were on within ten minutes of opening the box. Great value compared to buying the pieces separately.

Eczema on my arms has settled right down
My dermatologist mentioned hot chlorinated water can aggravate eczema, so I tried the shower filter. Six weeks in and the flare-ups have almost stopped. Wish I had done it years ago.
NPNathan P.AU · Wollongong, NSW
Fitted straight onto our rail shower, no adaptor needed
We have a rail shower with a rain head and a handheld, and it went on above the rain head in about a minute. Looks like it belongs there — the chrome matches the rest of the tapware. Pressure is better than before, which I did not expect from a filter.
Verified customer photoWOWendy O.AU · Toowoomba, QLD
Easy to install, and easy to change the cartridges too
Everything arrived well packed with three cartridges and a clear instruction sheet. Swapping one takes about ten seconds. Only tip: check the thread size on your shower before you buy, ours was standard and fine.

Also works on the bath spout
Bought it for the shower and ended up moving it to the bath mixer for the kids bath time. Same thread, same one-minute install. The water no longer smells like chlorine when the bath is filling.

Excellent water, took a moment to find the right adaptor
My tap was slightly unusual so I needed the second adaptor in the box. Support replied the same day with a photo guide. Once on, the flow is strong and the water is superb.
EVElena V.AU · Frankston, VIC
Presentation out of the box is excellent
Everything sat in a moulded foam tray — the stainless housing, three cartridges, the diverter and a bag of adaptors, with a proper instruction sheet and a spare O-ring on top. Nothing rattling around, nothing missing. It feels like a $300 product for $179.
Verified customer photoJLJosh L.AU · Cairns, QLD
Three spare cartridges included was the clincher
Laid all the parts out before starting and it is genuinely well made — the mesh cartridges are solid, the housing is real stainless not painted plastic, and the adaptors covered our older tap thread. Up and running in five minutes and our water finally tastes like nothing at all, which is the point.
Verified customer photoSDSarah D.AU · Sunshine Coast, QLD
Subscription timing is spot on
Cartridges arrive about a week before I need them, every quarter, each one sealed in its own little box so nothing gets knocked about. Swapping one takes ten seconds. Cancelled a different service to pay for this and have no regrets.
Verified customer photoARAmir R.AU · Blacktown, NSW
Arrived well packaged and well protected
Ordered the 3-pack and every cartridge came in its own box inside the satchel, not a mark on any of them. Build quality is better than the generic ones I was using — the mesh feels solid and the thread seated first go. Recommend it to everyone.
Verified customer photoRHRachel H.AU · Ballarat, VIC
Three months sorted in one delivery
Unpacked all three on the kitchen table and popped them straight in the cupboard. Genuine fit, no fiddling, and the flow came back to full strength the moment I swapped the old one out. The quarterly price is fair for what it is.

What OzFlow is not
OzFlow is not reverse osmosis. And that is by design.
Reverse osmosis
- Wastes 3–5 litres for every 1 litre filtered
- Complete demineralisation — strips calcium and magnesium
- Requires a pressure tank under your sink
- Professional installation and ongoing servicing
- Slow flow rate — you wait for your glass
OzFlow (advanced)
- Zero waste — 100% of the water is used
- Preserves essential minerals your body needs
- No tank — connects directly to your existing tap
- Installs in 30 seconds, no tools required
- Full pressure, filtered on demand

FAQ
Questions we get every day
Still unsure? Our team in Collingwood answers every email personally, usually within a few hours.
It fits 99% of Australian kitchen taps out of the box, and three adaptors are included in every carton for the unusual ones. If it still will not fit, send us a photo of your tap and we will either post the right adaptor free or refund you in full.
Once a month. Each cartridge is rated for roughly 2,000 litres, which is about a month of normal household use. Our 3-month subscription is $99 with free shipping, so the ongoing cost works out to about $33 a month — roughly $1.10 a day for the whole household.
No. Both the purifier and the shower filter hand-tighten onto existing fittings. Most customers are done in under a minute with no tools at all, which makes OzFlow ideal for rentals and apartments.
No, and that is deliberate. RO demineralises everything and wastes 3–5 litres for every litre it filters. OzFlow uses six targeted barriers that capture contaminants by size and chemistry while leaving dissolved calcium and magnesium in the water — zero waste, no tank, full pressure.
Yes. Our cartridge media is tested against NSF/ANSI 42, 53 and 401 protocols for chlorine, PFAS, lead, microplastics and hormone disruptors. We publish the average reduction rate for every contaminant rather than a single headline number.
Use it for 60 nights. If the water does not taste noticeably better, email us and we will refund the full purchase price — cartridges included. You do not need to ship the used cartridge back.
