Adjustable ION-Selective filter offers tailored carbonate, hardness, and corrosion protection levels in drinking water.

The Everpure Claris Ultra 250's unique water conditioning technology combines mineral adaptation, mineral stabilization and corrosion inhibition.

Features a 5-stage filtration process that includes:

  • Prefiltration
  • Carbonate hardness adjustment
  • Fine filtration
  • Highly efficient carbon block
  • Solid membrane filter

Removes harmful contaminants and unpleasant odours and tastes and removes scale.

Removes particles to 5µm (microns) for the highest equipment protection.

Operates in a vertical or horizontal orientation.


  • The system can be operated freestanding,
    lying horizontally or mounted vertically.
  • If mounting vertically to a wall, securely
    connect the mounting bracket to the wall
    using suitable screws.
  • Water pressure at the filter system inlet
    must not exceed 116 psi (8 bar). A pressure
    reducer valve must be installed on the
    water supply side of the filter system if
    the inlet pressure exceeds 116 psi (8 bar).
  • The shutoff valve must be installed upstream
    of the filter.
  • Refer to Installation, Operation &
    Maintenance Manual for cartridge flushing
    and startup.


  • Change Claris Ultra Cartridge when its
    precalculated water volume has been
    reached or at least once per year.
  • Change the cartridge when the capacity is
  • Always flush the filter cartridge at the time of
    installation and cartridge change.
  • Do not use hardness test strips to
    check for hardness reduction.
  • Please use a titration kit to check for hardness


  • Service Flow Rate: Maximum 0.5 gpm
    (2.0 Lpm)
  • Rated Capacity:
    • 2250 L for Espresso
    • 2500 L for Coffee/OCS
  • This capacity is based on influent water
    hardness of 180 ppm with standard bypass
  • First cartridge to effectively combine lime scale and corrosion protection.
    More capacity / lower costs for hot drinks and ice cube machines.
    Maintains PH in compliance with the EU drinking water regulation.
    Inhibits metal migration from machine parts.
    Safeguarding/enhancing energy efficiency of food service equipment.
    Sustained coffee roasting quality and optimised use of ingredients.
    Small footprint and low space requirement per litre.
    Cartridge family with widest capacity range (one head fits all).
    The new Everpure Claris Ultra is the first filter cartridge in the world to combine mineral reduction and corrosion protection through pH balancing. The result is that the Claris Ultra delivers the very best water quality for hot drinks and ice machines whilst also preventing scale formation and inhibiting corrosion and metal migration within the widest range of water hardness levels.

    At the heart of the Claris system is the unique DuoBlend bypass valve contained in the filter head. This valve provides unequalled accuracy for scale and acidity control by enabling precise adjustment of carbonate hardness in the filtered water. The bypass level can be adjusted to best suit the appliance type (coffee / espresso / vending / ice machines etc.) in order to maximise cartridge capacity and also take local water quality into account.

    * Capacity is based on OCS / Coffee use and on influent water hardness of 180 ppm with standard bypass settings. Capacity for Espresso is 2,250 litres.
