How much does whole home water filtration cost in Melbourne?

Most whole home systems in Melbourne cost between $3,000 and $5,000 installed. Where yours lands depends on:

  • The system: the filter size, the number of stages and the quality of the carbon.
  • The install: where it goes, and the plumbing at your home.
  • What's included: warranty, guarantee and how you get your filters each year.

Then there's the yearly filter change. A new set of Neptune filters is $300 a year, delivered to your door with GST included. That's about 82 cents a day for the whole home.

What's in Melbourne's tap water?

Melbourne's tap water meets Australian drinking water standards. To keep it safe on the way to you, chlorine is added, and in parts of Melbourne ammonia is also added, which makes chloramine. It lasts longer and smells less, so you often can't tell it's there.

That chlorine doesn't switch off at your front door. It's in every shower, bath and glass. A whole home system reduces it before the water reaches any tap, so you're not relying on a jug or a single shower filter.

The Neptune system: 3 filters, 5 stages

Stage 1

Sediment

Pleated polypropylene, 5 micron. Reduces sand, rust and grit from the street supply.

Stage 2

Limescale

Carbon block with polyphosphate crystals, 1 micron. Helps stop hard minerals forming scale on taps, glass and appliances.

Stage 3

Chlorine

Activated coconut shell carbon block, 1 micron. Reduces chlorine taste and smell.

Stage 4

Chloramine

The same coconut shell carbon targets chloramine, the longer-lasting treatment chemical.

Stage 5

Heavy metals

Helps reduce heavy metals picked up from older pipes.

  • Built to last: stainless steel cover, powder coated and treated, with copper piping.
  • Simple: water connection only, so no power and no gas. Bypass valve included.
  • Solid: mounted on the wall or concreted into the ground.
  • Filters that improve: every yearly change brings you our latest version.
