    I'm looking for a 'undersink' unit (https://www.uk-water-filters.co.uk/Your_Scale_Centurion_Undersink_Cartridge.html) but more detail on the page above. Trying to work out if it actually works or not. I can't find anyone else in the Uk selling them which makes me suspicious

    "Our Scale Centurion is a proven and fully tested technology.
    It works by extracting harmful dissolved limescale from your water via a patented process.
    The Scale Centurion beads mimic the natural tendency of dissolved limescale to crystallise by forming microscopic hard crystals on the media surface. But it accelerates the process before the scale can stick to pipe and other surfaces further downstream.
    Once the microscopic crystals grow large enough, they are freed from the surface by the water pressure / flow.
    When the Scale Centurion treated water dries on surfaces, these crystals form a fine residue that is easily wiped off without any need for scouring cleansers. Often you won't see any residue at all.
    Please note our salt fee softeners do NOT use Polyphosphates. These remove only 81% of Scale, release chemicals into the water and require regular replacement.
    The unique media in our softeners create a ceramic template which allows the calcium ions to form into non-scaling crystals (guaranteed). "

    It looks very like a ceramic filter to me, these remove particles but ions like calcium and carbonate

    I am sure there was a large discussion about these, or something similar. It involved a woman who was the importer.
    Do a search on here and see what you can find.

    Looks very similar to this one?...

    https://www.amazon.co.uk/Water-Softener-Alternative-effective-Prevention/dp/B00JVZE5P6/ref=as_li_ss_tl?ie=UTF8&qid=1461574256&sr=8-1&keywords=Water+Softener+Alternative+System,+Proven+99.6%25+effective+Scale+Prevention&linkCode=sl1&tag=bestspy-21&linkId=a56c34cdbe477019bda307e4c9c05611

    Read the reviews carefully. Even the 5 star review says..

    "The hardness is not removed but changed to a different "non sticky" state hence the change to what happens within the pipework. Does it work? YES Does it make the water feel soft and give better lather? NO - All the minerals in the water stay there but are changed to stop damage to your system."

    Shop around. That first web site says...

    "The usual price is £597 - Our special offer price is £497 - all inclusive" and
    "The replacement anti-scale media costs just £147. (It will last you a further 2 plus years"

    While here..
    https://www.uk-water-filters.co.uk/no-salt-softener-single-unit-20l-min.html

    Its "only" £297.

    but the casing appears to be a reasonably standard water filter case so you might be able to make your own using their "magic" filter in a third party case for less.

    Would I buy one? Not a chance.

    Some companies selling what look like similar products refer to a study by Arizona State University. I had a look and found what I think is that study here..

    http://softwaterspecialistsllc.com/wp-content/uploads/2017/01/2011-ASU-Study-No-Salt-Water-Conditioners.pdf

    It's worth a read. It refers to a "Template Assisted Crystallization" method of reducing scale which appears to prevent scale formation but not sure if it also makes the water feel better and/or reduce soap use. Also says.. "Life of Media – recommended change 12-18 months".

    What do you intend to use the processed water for?

    My Espresso machine/water dispenser in our fridge/freezer. The plan is to take the fridge apart and by pass the internal filter (which are meant to be replaced 6 monthly. Genuine cartridges are criminally expensive, but even using cheap generics I'll save money).

    Advice from a coffee forum (!) was to use Brita as per
    http://www.brita.co.uk/brita/en-gb/ppd/purity-c-quell-st/purity_c_quell_st.grid

    Designed for the catering industry, high capacity cartridges (so only need replacing annually) and can pick them up at a good price on eBay. I

    We buy our filter units and filters from Pozzani and have been happy over the years. I think the 6 month replacement interval is to do with biological growth in the filters, but in our case it is pretty obvious that the anti-scale needs replacing at that time anyway.

    Absolutely. :-)

    2 things I'd wanted for a long time and would now have trouble living without. I only drink one coffee most days but now it's a really good one.

    I thought chilled water would be a waste of time (it was the ice maker that had always been a want) but we drink a seem to drink a lot more water as a result (and less squash/hot drinks) and visitors seem the same.

    There are some things we bought/built into the house I'd not bother with again but the fridge isn't one of them

    Brilliant! Why have I never heard them before?

    Anyone know why do water chillers need softened water at all? If the water tastes bad, its not because of lime carbonates, look at sales of 'mineral' water.

    Maybe due to chlorine, but 'assisted crystallization' won't remove that.

    In our case, it's not for a chiller but for water that we put into the kettle, which my wife got fed up of descaling. I expect the same is true of coffee machines; I don't know about chillers.

    edit: For myself if I want to drink water, or squash, I drink it from the 'raw' water tap, specifically to get the minerals that cause hardness.

    DJH, if you are worried about your calcium intake, you wont find any meaningful amount by drinking tap water. How about swapping your espresso for a latte? Or a good old mug of milky tea? I Might Not Be A Doctor.

    Seriously, has anyone who has one of those big fridges tried just removing the expensive water filter? What's the point of it? Lime scale happens where water evaporates, and that's not in a chiller or ice maker.

    I'm not worried about my intake of calcium. I would be worried about my intake of sodium if I drank lots of softened water.

    I thought the general advice was not to drink softened water........

    The filters they come with don't soften - they're just carbon filters. Chlorine/metals/particles. I want to by pass mine, use a "cheaper to run" external filter that does soften and use the water for my coffee machine (which will die expensively if I keep running it on hard water).

    I've always mocked filtered water in the past (after all, our tap water is safe to drink) but the chilled, filtered, water from the fridge is a lot nicer than standard tap water. I go downstairs from the office rather than drink the water from our ensuite (and i put an unsoftened tap in there for the purpose).

    slight increase in sodium. Only advised to worry if you're specifically on a low sodium diet

    Another vote for the Pozzani under kitchen sink filters - we got the ix600 5 or 10 years ago. It tastes better - mainly I expect it's removing the chlorine that does that. Also swaps ions out for calcium phospate, maybe it helps a kettle/coffee m/c ? I always drink cold water using it, but don't normally bother filling kettle/cooking using it.
