The honest bit

Same job. Roughly half the price.

A six-stage reverse osmosis system installed under your sink is a well-understood job. Here is what it costs around Sydney, and what it costs with us.

Comparison prices are installed prices publicly advertised by other Sydney water filter installers, checked September 2026. We are not cheaper because the hardware is cheaper — it is Ecosoft, built in Belgium. We are cheaper because we install it ourselves and we do not pay for a sales team.

What we install

Eight systems. Every price fixed before we start.

Servicing

We service any filter. Including the ones we did not sell you.

$199 for an under-sink system, $250 whole-house, right across Sydney, the Central Coast, Wollongong and Canberra. No call-out fee, no inflated quotes, and no technician wandering around your house looking for extra work to invoice.

How servicing works

You call, we quote

Tell us the system and the suburb. You get the price on the phone, not after we have your kitchen apart.

One visit, one price

Cartridges, membrane check, pressure and leak test, sanitise, and a taste check before we leave.

No upsell, ever

If nothing else needs doing, we tell you nothing else needs doing. That is the whole business model.
