Defining 'Cleanest' Water: Purity vs. Mineral Content
When searching for the cleanest bottled water in Australia, it is important to understand that "clean" can mean different things. For some, it is water with the absolute lowest level of dissolved solids, achieved through advanced filtration. For others, it's natural spring water, which contains beneficial minerals and is protected from surface contaminants. Australian regulations, overseen by Food Standards Australia New Zealand (FSANZ) and the Australasian Bottled Water Institute (ABWI), ensure bottled water is safe for consumption, but do not dictate a single 'cleanest' option.
Types of Water and Their Purity
- Purified Water: This water, often sourced from a municipal supply, undergoes extensive treatment like reverse osmosis, distillation, or deionization to remove impurities. Brands like Pureau and Refresh Waters fall into this category, aiming for maximum purity and minimal dissolved solids.
- Distilled Water: A type of purified water created by boiling and condensing steam, removing almost all minerals and contaminants.
- Natural Spring Water: Sourced from an underground formation from which water flows naturally to the surface. Its purity depends on the natural filtration provided by the geological strata. Brands such as Beloka Water pride themselves on this natural sourcing.
- Mineral Water: Similar to spring water, it is sourced from a naturally protected underground source but contains a stable level of minerals. Beloka is also classified as a natural mineral water.
- Tap Water: Highly regulated and tested, Australian tap water is considered safe to drink and is a very clean, low-cost option. Many popular bottled water brands are simply treated tap water.
Australian Brands with Strong Purity Claims
Several Australian brands stand out based on their claims and processes:
- Pureau: Marketed as Australia's purest water, Pureau uses a three-step chemical-free filtration process that includes reverse osmosis. The company guarantees its water is 100% free from chlorine, bacteria, fluoride, and sodium. According to its website, Pureau's water is 100 times purer than the World Health Organization's minimum standards.
- Refresh Pure Water: Specializing in distilled water, Refresh uses a patented vapor compression distillation process. The company claims its ultra-pure water has an average of less than one part per million total dissolved solids (TDS) and is free from PFAS.
- Beloka Water: This premium mineral water is sourced from the Kosciuszko National Park, naturally filtered through 500-million-year-old rock strata. The Fine Water Society rates it as "superior," citing its low nitrate level (less than 1mg/L) as an indicator of purity. Beloka's purity comes from its natural source and minimal human interference.
The Microplastic Concern
One of the most pressing concerns with bottled water, especially those in plastic containers, is the presence of microplastics. A 2018 study, reported by 9News and the Australian Water Association, found microplastics in 93% of bottled water samples tested globally. A specific 2022 Australian study found an average of 13 microplastics per litre in local samples. The potential health impacts of consuming microplastics are still being researched, but it is a significant factor for those prioritizing absolute cleanliness.
Comparison of Australian Water Types
| Feature | Purified Water (e.g., Pureau, Refresh) | Spring/Mineral Water (e.g., Beloka, Mount Franklin) | Australian Tap Water |
|---|---|---|---|
| Source | Municipal tap water or bore water | Natural underground springs | Municipal water reservoirs |
| Purification | Distillation, reverse osmosis, deionization | Natural geological filtration, minimal processing | Multi-stage treatment, disinfection, fluoride added |
| Purity Metrics | Extremely low Total Dissolved Solids (TDS) | Contains natural minerals and electrolytes, low contaminants | Meets high national standards for safety |
| Taste | Often described as neutral or flat | Reflects its mineral composition | Varies by location and source treatment |
| Sustainability | Manufacturing and packaging have significant environmental impact | Source protection is key; packaging creates waste | Highly sustainable, zero packaging waste |
Factors for an Informed Choice
Making the right choice for bottled water involves weighing different priorities. Here is a list of key considerations:
- Prioritise Minimal Contaminants? If eliminating virtually all dissolved solids and contaminants is your goal, distilled or highly purified water like Refresh or Pureau is the closest option to 100% H2O.
- Prefer a Natural Profile? If you value natural minerals and a unique taste profile, a high-quality spring or mineral water such as Beloka is the better choice, provided it comes from a pristine, protected source.
- Concerned About Microplastics? The most reliable way to avoid microplastics is to opt for water not stored in single-use plastic. This includes Australian tap water or bottled water sold in glass containers, like Beloka.
- Value Sustainability and Cost? For those concerned about both cost and the environment, Australian tap water is a superior choice. It is safe, subject to more rigorous and frequent testing than bottled water, and avoids the environmental burden of plastic bottles. Installing a high-quality home filtration system for your tap is an excellent alternative.
Conclusion: The Best Choice Depends on Your Definition of 'Clean'
There is no single "cleanest" bottled water in Australia, as the term is subjective. For laboratory-pure, low-TDS water, brands like Pureau and Refresh, which use advanced purification, are top contenders. For naturally sourced, mineral-rich water, Beloka offers a high standard of purity from its unique geological source. However, the conversation around bottled water must also address its environmental and potential health costs. The presence of microplastics in many bottled waters is a genuine concern for consumers seeking the purest option. Ultimately, a conscious consumer will weigh these factors. While bottled water offers convenience, Australia's regulated tap water remains a very clean, safe, and significantly more sustainable alternative. For premium purity without the plastic, consider distilled water or choosing a spring water sold in glass bottles.
Ethical Sourcing and Packaging Concerns
Beyond purity, the ethical and environmental implications of bottled water are significant. The production and transport of plastic bottles consume vast amounts of energy and resources, contributing to climate change and plastic waste. Choosing locally-sourced water, like the 100% Australian-owned Beloka, or opting for brands that use recycled materials or glass, can help mitigate this impact.

A Final Word on Your Personal Preferences
Your definition of clean should guide your choice. Are you seeking maximum chemical purity, or do you prefer the taste and minerals of natural spring water? Are you concerned about microplastics or the environmental footprint? By considering these aspects, you can make a choice that aligns with your health goals, budget, and ethical considerations. In many cases, a high-quality tap filter offers the best of all worlds: cost-effectiveness, purity, and sustainability.
