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.

    Wish it had bone char instead of aluminium as a filter media for fluoride… but love the 3000 L filtering capacity.

    • webmaster (store manager)

      Hi Michael, FYI aluminium is very reactive metal where activated alumina (aluminium oxide) that we use in the UltraStream is made from the same thing as Ruby and Sapphires and will not react with water it uses micropores to trap the fluoride. The Problem with bone char is it needs a long contact time with the water to be any good and removal percentage drops off quickly.

    Really pleased with the pH reading on our water once the new cartridge was installed. Would have been nice to receive a reminder of the installation process (or a brochure with the link to the undersink manual (I forgot about the ‘John Guest’ tool – not sure I recall where I’ve put it, but I managed without it (eventually!))

    I received the replacement cartridge quickly and we were grateful and it was easy to install. However a few days later I emailed the company to ask what to do about the fishy tasting water and they still haven’t responded. It is now days since I emailed, the water now tastes ok but the email site suggested I would receive a reply in minutes!

      Hi, Judith, our apologies. Most of the time we do get back to people fast. Somehow you slipped through the cracks. Glad to hear the taste has righted itself. In drought conditions like this we have seen it before how strange things happen!

    Easy online ordering, quick delivery and great communication. As I use this as an underbench system, it was disappointing that there wasn’t any installation instructions included.

    >> Hi, It’s in the manual you can get it again here https://www.alkaway.com.au/downloads/ultrastream/ultrastream-manual-final.pdf

    Is it normal for a white residue to be visible on glass after dinking the water. Also seems to have a slightly soapy taste.!

    • Ian

      Hey julie,

      Yes it is. We were given the choice of ultrapure ingredients that have that effect, or less pure ones that fully dissolve! We chose the purity over the convenience. I’m using the new Alkaway greens and I add my tsp of AlkalIne booster, then blend it. This overcomes the grittiness.

    could be cheaper

    Holidays too long in the hottest most water comsuming part of the year..

  14. Ann-Marie von Douglas (verified owner)

    Always perfect, but this time a bit of a hiccup because the address line was not complete and the delivery was returned to you and delayed. Doesn’t affect the quality of the water however! 🙂
