Review Great Water Australia Complete Home Water Filter System

Review: Great Water Australia Complete Home Water Filter System
After careful consideration and comparison of several brands, I chose the Great Water Australia Complete Home Water Filter, and I can confidently say it has exceeded expectations.
From the outset, the customer service was professional and responsive, ensuring a smooth installation process. The unit itself is robust, well-designed, and seamlessly integrated into our home water system.
What impressed me most is the noticeable improvement in water quality. The filtered water is visibly clearer, tastes noticeably cleaner, and is free of the chlorine odour and sediment we previously experienced. Whether for drinking, showering, or cooking, every tap in the home now delivers high-quality water that feels softer on the skin and safer for the family.
Additionally, knowing that it removes a wide range of impurities—while retaining essential minerals—gives me peace of mind regarding long-term health and plumbing protection.
I highly recommend Great Water Australia for anyone seeking a reliable, Australian-made whole-house water filtration system that delivers on performance, durability, and customer support

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

Glen Dickinson15 Dec 2024

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. ”

Paul25 Feb 2024

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!
Regards, Morreen
