  • 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.

More information on the UltraStream Replacement Cartridge

Important note for all water filter customers. No filter lasts forever. 3 factors affect the lifespan of the filter.

  1. The quality of the filtration media.
  2. The amount of filtration media.
  3. The amount of ‘gunk’ in your water.

For this reason, we recommend replacing the UltraStream Replacement Cartridge every 12 to 14-month. Although we have the world’s best filtration media in generous amounts, any filter, no matter how good it is, is a ‘toxic waste dump’ collecting the toxic chemicals and debris in your water and preventing its passage into your body.

Note: To help reduce the environmental load on our landfills the Replacement Cartridge for the Stainless Steel and Black UltraStream will be supplied without the Stainless Steel (SS) sleeve/cover (unless ordered by calling 1800 268 469). This is in response to requests from the majority of our customers. So, when replacing the Cartridge please keep the cap and SS sleeve to put onto the new cartridge. Thanks.
