More information on the UltraStream Replacement Cartridge

The patent-pending UltraSteam water filter uses the highest quality patented filter media plus exclusive O-Dobi alkalizing, ionizing, and hydrogen producing media. It also supplies infused magnesium and calcium through the life of the filter, calculated and tested for over 3600 litres.

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.

  6. Greg Tombs (verified owner)

    Even after a few weeks the unit continues to drip after use, then takes time then to get a steady stream each time. I have only changed the filter. Is there anything else I can do to alleviate the issue

    • webmaster (store manager)

      As you probably already know its a side an effect of the Hydrogen production and should slow in a couple of weeks. But it’s defiantly worse on some water supplies, we are working on ways to reduce it. If it’s still a problem call or email us and we should be able to help.

  15. Graham (verified owner)

    New replacement cartridge was easy to install. After running it in for 20 minutes I had my first drink – and later had to visit Mother Nature. This reassured me that the filter was working to perfection. Now body has readjusted to drinking the purest water money can buy. A great and important product to have and to use daily in one’s home for better health and sense of well-being. No argument need be entered. Graham.
