Everpure® ESO / Claris Cartridges

Softening, Filtering & Buffering


Claris Cartridges:

The rule of thumb is to change these cartridges once a year.  There is a Flow Meter (#EV4339-31/32) that monitors the gallons used and indicates when it is time for a filter change.  If you do not have this meter, you can retro-fit it.  Otherwise, we recommend every 12 months.


There are 6 different sizes of Claris cartridges to choose from:

#EV4339-80 Claris Ultra S – 0.50 gpm flow rate – 660 gallons*

#EV4339-81 Claris Ultra M – 0.50 gpm flow rate – 1,109 gallons*

#EV4339-82 Claris Ultra L – 0.50 gpm flow rate – 2245 gallons*

#EV4339-83 Claris Ultra XL – 1.0 gpm flow rate – 3,196 gallons*

#EV4339-84 Claris Ultra XXL – 1.00 gpm flow rate – 5,283 gallons*

#ev4339-86 Claris Prime – 1.00 gpm flow rate – (please refer to spec sheets for details)


ESO Cartridges:

There are two models to choose from, the ESO6 and ESO7.  Both cartridges are interchangeable and fit into any Everpure QC head or manifold.


#EV9607-10 ESO6 – 0.50 gpm flow rate – 4,100 grains per cartridge

#EV9607-25 ESO7 – 1.0 gpm flow rate – 5,300 grains per cartridge
