    Thank you, appreciated the heads up to replace the cartridge. We love our clean water and get regular compliments from our visitors on the quality of water. We always endeavour to take enough water from home when away.

    I am thankful for the yearly reminder and the prompt delivery of our Ultrastream. This year I asked if there was a little extension pipe and lo and behold it was in the parcel – no problems

    The replacement cartridge is easy to replace. I drink a glass of water before other beverages and the water from the UltraStream makes a lovely cup of tea it’s always refreshing YEAH!!

  13. Lachlan –

    Very prompt service , great products, water tastes sweet.

  14. Graham –

    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.

  15. Michael Halberstadt –

    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.

  16. John McKay –

    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!))

  95. Howe Hee –

    I certainly support the idea of reusing and thus reducing environmental load. However, to encourage people to be environmentally friendly, the price of the filter should reduced as the material costs for the overall product is reduced (no SS sleeve and cap are removed).

    My Ultrastream water filter is an essential part of my life – I never want to be without the wonderfully heathy, pure, alkaline h20 it provides me!
    My recent purchase of a replacement cartridge is actually my 3rd one – with my everyday usage of this water filter system I replace the cartridge every 12 -16 months to ensure its working properly. It’s just a single person household use for me.

    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!

    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!

  145. Neil Cunningham –

    Thanks again. Greet service.

  146. Allana J. –

    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.

  151. Doug Wakefield –

  152. Jennifer Kennedy –

    Our replacement cartridge arrived in record time! Thanks Alkaway!

  153. Laura Fett –

    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.

    Although we have no issues with the filter, the prices are going up every year and we may have to switch to another solution with more reasonable replacement costs.
