We send a reminder when your filters need changing. You decide when. You can DIY or book us — no lock-in either way.
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.
50% of our profits go back into the community. We sponsor junior and community sport clubs across Perth — local cricket, soccer, footy, netball. Get filtered water at home, support the next generation playing sport in your neighbourhood. That's the deal.
