If you've ever wondered why your CHF filters cost $348 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.
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.
