Why Great Water Filters Australia?
Years of Business
Installing Whole House water filters is becoming increasingly popular across the Northern Territory, from Darwin to Alice Springs. This system ensures purified water flows through every pipe, tap, and shower in your home, providing protection for your family and your plumbing.
It’s not just about clean drinking water — it’s a total home water solution that also extends the life of your appliances, including showers, baths, and dishwashers.
Our systems are available in a range of configurations, including ultraviolet (UV) sterilisation, water softeners, and activated carbon filters, so you can choose what suits your local conditions best.
Many NT homeowners who rely on rainwater or bore water choose our Whole House systems, which come fully installed with a complimentary $500 UV or softener upgrade. This helps reduce bacteria, hardness, and sediment for safer, better-tasting water.
Don’t let untreated or mineral-rich water affect your home — you can enjoy clean, clear water across the Northern Territory for less than you think.
We also offer interest-free payment plans and free professional installation across Darwin, Palmerston, Katherine, and Alice Springs.
