What Customers Say

Pure water taste again

Since being switched to the Albany water supply here in WA the water was so full of calcium. It was building up on the shower screen and was visible inside the kettle (had just bought a glass kettle) so all the particles were visible while the water boiled. Now that we have the full house system all that has gone, no more mineral build up, shampoo lathers again, drinks taste right. I would recommend this system to everyone

Good enough that our neighbours want one

We ordered the Wellness Whole House System. At the time, it was not in stock, so we had to wait a few weeks before it was installed. During the process, we were kept up to date with progress. We were happy that they could arrange an installer for us living in regional Queensland. The installer did a fantastic job and mentioned that he had installed a few of these systems in the area, and they are very reliable. We have gone from hard chlorinated water to soft water we enjoy drinking. Our neighbours are now looking at ordering their own systems.

Great Product, Awesome Service

“Very happy with the quality of the product and the service. We have gone from having dirty, hard water (awful town supply!) to clean water that feels soft after the installation of a whole-house filter. The wholeprocess was quick, taking less than a week from my first approach to Great Water to the filter being installed. The plumber assigned was friendly and professional. A very small amount of seepage we had after installation was fixed within a day after one text message to Great Water. While the price may put some off, we see it as a saving on the jug filters we no longer need to buy, and on the damage the old hard water used to do to the bathroom, kitchen and cars. I would definitely recommend Great Water's household filter system. ”

Great Water Filter system

We are really pleased with the system we had installed to reduce the amount of scale build up in our drains and shower heads. It gives me peace of mind that my expensive appliances are also protected. I looked for months for a company that could provide a comprehensive system we were needing to filter the water coming into the house. We notice a big difference. It is wonderful that we get reminders when our filters are due for replacement. Thank you so much Great Water!

FAQs

What types of water filtration systems do you offer?

We supply a wide range of water filtration systems including whole house water filters, under-sink water purifiers (reverse osmosis systems), UV water purification, and water softening solutions — all engineered for Australian homes and tailored to different water quality needs.

How do reverse osmosis water purifiers work?

Reverse osmosis (RO) water purifiers use multi-stage filtration to remove up to 99% of contaminants — including chlorine, fluoride, heavy metals and dissolved solids — for ultra-pure drinking water. Many RO systems also restore essential minerals for balanced hydration and great taste.

Will a water filter system improve the taste and safety of tap water?

Absolutely. Our water filtration systems are engineered to reduce chlorine, sediment, chemicals and odours — giving you cleaner, better-tasting water for drinking, cooking and everyday household use, while also protecting your plumbing and appliances.

Do you offer water filtration solutions for tank or bore water?

Yes. Our range includes filtration systems designed for tank, bore and untreated water supplies, including sediment filtration and UV purification options to handle biological contaminants and improve overall water quality.

What is a whole house water filter system?

A whole house water filter system treats all water entering your home, ensuring clean, filtered water from every tap — including showers, laundry, kitchen and garden outlets. These systems can remove sediment, chlorine, bad tastes and odours, and other common contaminants.

Can a water softener help with hard water problems?

Yes. Water softeners are available to reduce hardness by conditioning water and preventing scale buildup in pipes, appliances and fixtures — helping protect your plumbing and improve the feel of water on skin and hair.

Can I have different filtration systems for the whole house and drinking taps?

Yes. Many customers combine a whole house water filter with an under-sink reverse osmosis purifier for the highest level of drinking water quality while ensuring all tap water in the home is filtered and safe.

Are your systems suitable for Australian drinking water standards?

Yes. Our water filter and purifier products are engineered for Australian conditions and are designed to help you meet or exceed local expectations for safe, clean, and high-quality household water.
