Save money and help the environment
- Saves you big money. Cost is 22c/litre for the first year, and only 8c/litre after that (replacement filters).
- Saves thousands of single-use bottles (x2000, 1.5 litres) from going into the environment.
- Saves freight and fuel costs to transport that amount of bottles around the Australia.

UltraStream Filter Life Expectancy
Every water filter has a lifespan, and the UltraStream is no exception. The UltraStream Replacement Cartridge is rated for up to 3,000 litres of filtered water. Based on average household use, this translates to:
8 litres per day – suitable for a family of 4
To ensure you’re always drinking clean, high-performing water, we recommend replacing the cartridge every 12 months, or sooner if your daily use exceeds the average.
The filter lifespan has been independently tested, please see independent test here
Environmental Notice: To reduce landfill waste, UltraStream Replacement Cartridges for Stainless Steel and Black models are now shipped without the stainless steel sleeve by default. Please retain the sleeve and cap from your current cartridge and transfer them to the new one.
In Australia, we do not currently have a method of disposing of these type of filters for recycling, due to the hazardous waste they contain, after filtering. It would require specialized recycling facilities that can safely extract and dispose of the hazardous materials, which we currently do not have in Australia, so they will need to be thrown in the garbage bin and allowed to break down slowly over time.
Need this in Ballarat. Water disgusting without this.
Excellent water filter
Easy to replace
That time of year again to replace the old cartridge. I seem to get more months life out of each cartridge than is commonly expected. As usual, the task was simple and easy. It’s a great product and the quality of water obtained is unrivalled.
Wish it was cheaper
Best water filter I have had and not as pricey as some
Wonderful water filter.
Very happy with this product
I’ve ordered an UltraStream replacement water filter several times now and have been extremely satisfied with the quality of drinking water they have issued. I strongly recommend this product for anyone wishing to experience good tasting and odor-free H₂O.
Easily changed!
As perfect a water filter system as possible for my safe water everyday living needs.
I have been using these filters for years, and love the water and the ease of replacing the filter. No mess, no fuss, great tasting water!
Happy with the new filter, it makes the drinking experience much better!
No other filter comes close to the water quality this delivers.
Great product.
Love the filter does the job well
This is our first replacement cartridge for the caravan. You can taste the difference when you replace the filters, the water is easy to drink again. The only negative comment we have is the thread snapping off when we took the filter off, we’ll see if the filter does it again when it needs replacing
