A filter only works while the media is fresh. Each OzFlow cartridge is rated for roughly 2,000 litres, which for the average Australian household is about one month. Our subscription sends three genuine cartridges every quarter — free shipping, cancel or skip anytime, and $30 cheaper than buying them one at a time.
Spent carbon stops adsorbing and can release trapped contaminants back into your water. A fresh cartridge each month keeps performance at 100%.
We time deliveries to land a week before your third cartridge expires, so you always have one in the cupboard.
OzFlow has introduced a genuinely new approach to cleaner drinking water — as Australian households rethink how they filter at home.

Water that tastes clean, crisp and refreshing — from the very first glass

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.
Verified customer photoCartridges 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 photoOrdered 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 photoUnpacked 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.
No. Every OzFlow product is designed for tool-free installation. The Water Purifier System uses a push-fit tap adaptor and the Fresh shower filter screws straight onto a standard Australian thread. Most customers are up and running in under five minutes.
Change your drinking water cartridge once a month for peak performance. Our 3-month subscription supply is $99 and arrives before you run out, so you never drink through a spent filter.
No. The 0.01 micron membrane blocks contaminants by size while the mineral stage keeps calcium and magnesium in the water. That is why OzFlow water tastes fuller than reverse-osmosis or distilled water.
Use it for 60 nights. If you are not convinced, email us and we will refund you in full — you do not need to send the unit back in original packaging.
Shipping is free Australia-wide. Orders are dispatched within 1–2 business days and delivery typically takes 7–14 business days, with a tracking number emailed to you as soon as the parcel is scanned.
