Why Great Water Filters Australia?
Years of Business
Installing Whole House water filters is an increasingly popular choice for homeowners throughout South Australia, from metropolitan Adelaide to regional towns. This complete system ensures purified water flows through every pipe, tap, and shower in your home.
It’s not just about great-tasting water — it’s a whole-home solution that helps protect your plumbing and appliances from scale, sediment, and chlorine, extending their lifespan while improving comfort and cleanliness.
Our South Australian range includes ultraviolet (UV) sterilisation, water softeners, and activated carbon filters, allowing you to choose the ideal system for your local conditions.
Many South Australian customers using tank or bore water opt for our Whole House systems, which come fully installed with a complimentary $500 UV or water softener upgrade. This helps neutralise bacteria, reduce hardness, and improve water quality in areas such as the Barossa, Clare Valley, and Fleurieu Peninsula.
Don’t let untreated or mineral-heavy water affect your home — enjoy clean, clear water anywhere across South Australia for less than you might expect.
We also offer interest-free payment plans and free professional installation throughout the state.
