More information on the Replacement Cartridge

The patent-pending UltraSteam 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 over 3600 litres.

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

  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 a 12 to 14-month filter replacement. 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.

    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

      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.

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

    • webmaster

      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.

    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.

    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 had completely forgotten the set up rule and did not find any hints on the box about how long to run the filter. I could not work out what was wrong with our foul tasting water at first. I threw the first 2 lts but had forgotten to run it for 20 mins. Please include these details on the box more clearly. I had to do an internet search to find what was wrong. God knows what I have drunk- carbon I suspect!

    I’m extremely happy with the functional capabilities of this product – its second to none. What I’m disappointed about is the price… one would expect with economies of scale that the price of goods should come down? Yours has done the opposite! I have been an Alkaway customer for 10 years and spent thousands of dollars with you, so the perception of excessive price inflation doesn’t sit well with me.

    Always happy with your efficient and quick delivery of my replacement filter. Been using your filter now for many years, and I don’t like drinking other water, because I can taste the difference, even when I go out I take my own water bottle. Thank you all, may we have many more years together.

    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!

    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.

    The fitting on my Ultrastream machine was incompatible with the filter you sent. I expected you would know what filter to send given you supplied the original machine.
    When I asked for a fitting which would fit properly your person told me to send photos? Photos of what? I work full time and don’t have the energy to frig around sorting this out. So I asked my son make a part in his workshop and he got it working properly.
    I am very disappointed that you did not supply the correct part and that you then wanted me to provide evidence which you should already have since you sold me the original unit.
    I have been a customer of yours for many years and have, previously, recommended your company.
    This would never have happened with Leon.

    • Ian

      hi, Laura, thanks for your blast.

      it IS a problem. Every new faucet released (all from China) seems to have a new thread! We supply a range of adapters that fit (we estimate) 95% of faucets and we have imported a range of special faucet adapters for people who have the misfortune to buy a new ‘naughty’faucet with non-standard thread size or access.

      We do take it very seriously and it’s something all water filter vendors share.

      We are just now finishing a web page for a new form of controller that doesn’t attach to your faucet at all. It requires a small hole in your sink or benchtop but it works well, looks good, and is very sturdy.

      By the Way Leon is still here. He’s our longest serving team member!

      You must have a very competent son!

    Hey Ben, with respect, the only alternative product that gives molecular hydrogen (less) and alkalinity (less) but is nowhere near the filtration capability is an electronic ionizer currently sold for around $5000.
