How it works

Getting clean water
is simple.

No high-pressure sales visits. No complicated contracts. No upselling. Just a clear path from enquiry to clean water at every tap.

01

Free water assessment

Tell us your suburb and household setup. We check your Water Corporation data and recommend the right solution — free, no obligation.

02

Honest quote

Upfront pricing — no hidden call-out fees, no annual contracts. You see exactly what you're paying for before any work starts.

03

Perth installation

Replacement filters ship Australia-wide — dispatched in 1–2 business days, arriving in 5–7. Perth metro installations and new whole-home installs done by Perth locals, not subcontractors.

04

Service when you want it

We send a reminder when your filters need changing. You decide when. You can DIY or book us — no lock-in either way.

CHF Customers

Why CHF customers
pay more.

If you've ever wondered why your CHF filters cost what they do — renewal quotes customers report to us run from $348 to $548 a year — and why you can't seem to find them anywhere else — you're not alone. The 15" × 4.5" proprietary cartridge size makes CHF systems dependent on one supplier: CHF themselves.

We supply the compatible three-stage filter set that is designed to fit the 15" × 4.5" housings used in CHF systems. No contract. No service callout fee. No lock-in.

✗Proprietary 15" × 4.5" cartridges only available from CHF
✗Annual service contract fees on top of cartridge cost
✗Hard to find independent service providers
✗No choice in media quality or supplier

Why we exist

Good water.
Good for the community.

We started ProperWater because we believed filtration in Perth had become more about contracts and proprietary lock-in than about doing it properly. We wanted to do the opposite — straightforward filters, fair pricing, local service.

We put half our profits into sponsoring local sport. Junior and community clubs — local cricket, soccer, footy, netball. Get filtered water at home, support the next generation playing sport in your neighbourhood. That's the deal.
