Calcium scale builds up on shower screens, taps and inside your hot water system, washing machine and dishwasher, wearing them our faster than they should.
This 3-stage system treats the water where it enters your home, so every tap in the home runs cleaner water, not just the kitchen sink.
Designed for larger households, the high-capacity 20″ cartridges provide excellent flow while helping reduce sediment, chlorine and heavy metals, as well as softening Perth hard water.
If you have bore water, it will require testing to establish correct cartridge combination.
Testing can be do through Eurofins APAL Belmont. The test result can then be viewed by us to begin the discussion on your needs.
Water passes through three filtration stages before entering your home’s plumbing.
The high-flow design allows multiple taps to operate simultaneously without a noticeable loss of pressure in most Perth suburbs. Where unusually low or high mains pressure exists, we’ll discuss the most suitable solution during your consultation.
Stage 1 – Sediment Filter 5 μm
Reduces dirt, dust, rust and other suspended particulates, helping protect the cartridges that follow. In Perth’s water conditions, we generally recommend replacing the sediment cartridge every six months to maintain optimum performance.
Stage 2 – Water Softening Resin
Using an ion exchange process, reduces calcium hardness to help minimise scale build-up on plumbing fixtures, hot water systems and household appliances while improving the feel of the water.
Stage 3 – Chlorine Removal and Heavy Metal Reduction Cartridge 1 μm
Reduces chlorine taste and odour. Manufacturer testing reports chlorine reduction of up to 99.9% under specified test conditions.
Using an ion exchange process, reduces a range of heavy metals while conditioning the water before it is distributed throughout the home.
A licensed plumber is required for installation.
Every installation includes a bypass valve, allowing the filtration system to be isolated during maintenance without interrupting the household water supply.
Installation is not included in the listed price.
If you’re located in Perth, we can arrange installation through one of our trusted licensed plumbing partners. Contact us for an installation-inclusive quotation.
Like all filtration systems, the cartridges require replacement at recommended intervals to maintain performance.
Under typical Perth scheme water conditions, we generally recommend:
To make ongoing maintenance easy, we’ll send you reminder emails when your cartridges are due for replacement, including details of which cartridges you’ll need.

I have very hard water in my area and noticed a difference almost instantly, and my animals are drinking more water now which is great to see. Mavis and Rob have been fantastic from the start, being very responsive and eager to answer any questions.

Rob and Mavis have been great service to me and my new home (which I had to suffer and wait for ~4years to get house completed). They are excellent in providing advice that are practical and pragmatic. Please, I cannot promote them further. have a 3-stage full house water filter system, and I love it. and I agree with them, “It is a MUST”.

We installed the whole house water system last year and it has helped us remove water contaminants like rust. It has also saved some of our house hold appliances like kettle that always had calcium.

I didn’t know businesses like this still existed. It was a pleasure to deal with West Oz Water Filters. Rob went out of his way to make sure all was right. I couldn’t be happier and trust me it all works very well. THANK YOU Ron Pollard Morley
