Distillation removes virtually all impurities, minerals, and contaminants.
Prevents mineral buildup that can damage expensive appliances and machinery.
Unlike tap water, distilled water provides reliable, predictable results every time.
Essential for medical equipment, laboratories, and precision instruments.
Distilled water is water that has been purified through distillation—a process where water is boiled into steam and then condensed back into liquid form. This removes virtually all impurities, minerals, and contaminants, resulting in extremely pure H₂O.
Yes, distilled water is safe to drink. However, because it lacks minerals found in regular water, it may taste flat. For drinking purposes, many people prefer mineral or spring water for taste and mineral intake. Distilled water is primarily used for appliances and applications where pure water is essential.
While you can use tap water in emergencies, it's not recommended for regular use. Tap water contains minerals that can build up in your CPAP humidifier chamber, potentially creating breeding grounds for bacteria and reducing the equipment's lifespan. Distilled water is strongly recommended by most CPAP manufacturers.
Unopened distilled water can last indefinitely when stored properly. Once opened, it's best used within 1-2 weeks for sensitive applications like CPAP machines. For general use, opened distilled water remains usable for several months if kept sealed and stored in a cool, dark place.
Distilled water is available at supermarkets (Coles, Woolworths), hardware stores (Bunnings), automotive stores (Supercheap Auto, Repco), pharmacies, and online retailers like Amazon Australia. For the best selection and prices, we recommend checking the products on this page.
Both types are purified water, but they use different processes. Distilled water is created through evaporation and condensation, while demineralised water uses ion exchange or reverse osmosis. For most applications, they can be used interchangeably. However, distilled water is generally considered purer and is preferred for medical and laboratory uses.
Welcome to Distilled Water Australia, your comprehensive resource for finding and comparing the best distilled water products available across Australia in 2026. Whether you're looking for pure water for your CPAP machine, steam iron, car battery, aquarium, or laboratory applications, we've researched and reviewed the top products to help you make an informed decision.
Our team has extensively researched the Australian distilled water market to bring you unbiased product comparisons. We analyse factors including purity levels, packaging sizes, value for money, customer reviews, and suitability for different applications. Our goal is to help Australians find the right distilled water product for their specific needs.
Distilled water is created through a purification process that involves boiling water into steam and then condensing it back into liquid form. This process effectively removes minerals, impurities, bacteria, and other contaminants, resulting in water that is approximately 99.9% pure H₂O. This level of purity makes distilled water essential for applications where mineral content could cause damage or interference.
Australian households and businesses use distilled water for numerous purposes. CPAP users rely on distilled water to prevent mineral buildup in their humidifier chambers, ensuring optimal performance and hygiene. Automotive enthusiasts use it to top up lead-acid batteries, as minerals in tap water can reduce battery efficiency. Home users find distilled water perfect for steam irons, preventing limescale that can stain clothes and clog steam vents.
Beyond household use, distilled water is crucial in scientific laboratories for experiments requiring precise measurements, in medical facilities for sterilisation and equipment, and in aquariums where water chemistry must be carefully controlled for sensitive marine life.
