Australian owned and run

A small Australian team obsessed with what comes out of your tap

OzFlow started because filtering your water in Australia was needlessly hard: either a $30 jug that barely helped, or a $2,000 under-sink system with a plumber's quote attached. We wanted the middle — genuine multi-stage filtration you can install yourself before dinner.

Our standards

What we hold ourselves to

Four rules that decide which products we stock and how we talk about them.

Nothing should need a plumber

If a product cannot be installed by one person in five minutes with no tools, we do not sell it. Filtration only helps people who actually set it up.

Say what it does, not more

We publish micron ratings, media types and cartridge life. No vague wellness language, no invented health claims, no fake countdown timers.

No lock-in, ever

Our cartridge subscription is $99 a quarter and you can skip, pause or cancel in two clicks. If we have to trap you to keep you, we have failed.

Fewer bottles, less waste

Each cartridge replaces about 4,000 plastic bottles. Send your spent cartridges back to us with our free return label and we recycle the housing.

Since 2021

How we got here

    2021

    A cloudy glass in Footscray

    Our founders moved into a 1960s rental where the water ran brown after mains work. Two supermarket jug filters later, they started reading membrane spec sheets instead.

    2022

    First 500 units

    We imported a small batch of ultrafiltration units, tested them across hard-water and soft-water suburbs, and sold out by word of mouth.

    2024

    Faster dispatch

    We tightened our fulfilment process so every order is dispatched within 1–2 business days, and support is still answered by the same small team.

    2026

    20,000 Australian homes

    Kitchen purifiers, shower filters and a cartridge subscription that arrives before you run out. Same idea, more rooms of the house.
