    Oliveri produce a number of different filters, non promoted as being for coffee machines. They will make your drinking water taste better, but for coffee read the info on Water filtration.

    WHen my kitchen was installed a water filter was included on the cold water line at the sink. This is the cartridge type that is fitted: Inline Water Filtration System Replacement Cartridge for Standard Water Use – Oliveri

    I live in Brisbane and find it improves the taste of water a lot. I'm interested to know how it will benefit/harm a coffee machine with Stainless Steel boilers? I gather they are more particular than brass or copper boilers?

    I wonder if a more effective cartridge is able to fit in this system (not sure if its a standard fit or proprietary)

    Suitable...not optimal. Big difference.
    What micron size particles do they filter to?

    For instance avge coffee industry std filters will have an avge rating of 15microns.
    Meaning they may filter out particles greater than 15microns. Note not do.
    These are Single stage.

    In hard water areas such as Brisbane (+60ppm/-240ppm CaCo3) coffee industry std filters Dont achieve water to the LM requirements.

    An Ionic exchange, cartridge water softener plus 1 or 2 stage filtration will likely achieve the result your seeking.
    Suggest having samples tested. Ex sponsor here Bombora provide a free service.

    You dont indicate your location, so uncertain whether you have any local service provider.

    These systems are not expensive in relation to the quality of water / espresso they contribute to And long term maintenance of your machine is greatly enhanced. Its not uncommon for a home machine to ext its life past 15 or 20 years, whereas the avge commercial machine is swapped out in around 5years,Plus 3-6 mths servicing = why the avge cafe doesnt run better filtration.
    Plus the avge site is not there to produce exceptional coffee!
    When all the above is usually controlled by the roaster at theyre cost, this explains why coffee ind std falls well short of what the home enthusiast should seek to install.
    Report back your findings pls.

    Ok thats good to know. Ive seen a few places mostly sell the Poly/GAC filters in the 1025 size as suitable for food industry and coffee makers. Thought could be an option maybe

    Polyphosphate GAC incorporates a taste filter: GAC is Granular Activated Carbon which will adsorb lots of flavour active compounds.

    No experience using these for coffee machines, sorry, but since calcium and magnesium phosphates are very insoluble it should help. Phosphate pretreatment is standard routine for boiler water in industry.

    Hey folks,

    looking at setting up a water filter tap and wanted to know options for espresso machine softening filters that will fit into a 1025 style filter. Was doing some reading and the polyphosphate GAC seem like they could be an option. Im bit unsure on Cation resin as it appears the water needs more time to pass through the beads than what the small filter can offer. Any insights and places to get whatever filters would be great. Plan on putting taste filter in line too.

    thanks
Working...
