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's in your water

What our filters actually remove.

Sydney tap water is already safe — what a good filter removes is the chlorine and fluoride added on purpose, the rust and sediment from older pipes, and the dissolved metals and PFAS that a jug filter can't touch.

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.

“After lots of research, I chose PH Water Filters and couldn’t be happier. John arrived promptly the very next day, was friendly and professional, and installed the filter in about an hour. He answered all my questions, and I’m so pleased to have quality drinking water again.”

“John did an excellent job installing a reverse osmosis system and chrome three way mixer tap. Couldn’t be happier with the service and communication… Im very impressed with the upfront reasonable pricing, the installation being included and no hidden extras.”

“John from PH Water Filters did an absolutely outstanding job installing our reverse osmosis system. The installation was extremely neat and clean, and he took the time to explain everything in detail so we understood how the system works and how to maintain it.”

“I’ve used many filters before, but nothing compares to PH Water Filters. The alkaline system has made a huge difference in my family’s health.”

Lifetime warranty. Yes, lifetime.

Every six-stage reverse osmosis system we install — Standard PRO, Balance and Alkafuse — is covered by a lifetime warranty for as long as we look after it. Keep the annual service on schedule (a fixed $199 a year, no call-out fee) and you will never pay for a failed part or a repair call-out on that system. That is how confident we are in Belgian-made Ecosoft hardware.
