2 General Information

2.1 Function and Application

The BRITA PURITY Quell ST Water Filter System is used to remove carbon from drinking water to
prevent limescale deposits in downstream appliances. Depending on the by-pass setting, the fl ow
method is used for the selective removal of calcium and magnesium ions as well as heavy metals
ions, such as lead and copper. Furthermore, the fi lter material reduces cloudiness and organic
impurities, as well as contents which affect taste and odour (e.g. chlorine residues) in the fi ltrate and
bypass water. By-pass settings on the connector head are used to set the total hardness reduction to
the local water hardness or the requirements of the application in order to achieve an optimum water
quality. The fi lter systems are available in 3 different fi lter system sizes (PURITY 450, PURITY 600
and PURITY 1200) and each in the version without integrated measuring and display electronics
or with measuring and display (Advanced Control System, ACS-Technology) electronics.
Filter systems with ACS Technology show you the current remaining capacity and bypass setting of
your fi lter cartridge, the set type and size of the fi lter system and the last replacement date of the
fi lter cartridge. This ensures optimum fi lter control and water fi ltrate quality. Further information on
the fi lter system with ACS Technology can be found in Chapter 5.2.
The unique IntelliBypass ensures a constant by-pass proportion over the entire usage periods, irre-
spective of the volumetric fl ow of the terminal device concerned. The result is a consistently high
water quality specifi cally tailored to the application-specifi c requirements and the local water condi-
tions.
Typical applications for BRITA PURITY Quell ST water fi lter systems are coffee and espresso
machines, hot and cold drinks vending machines as well as steam ovens (combi ovens) and air humi-
difi ers.
The fi lter system is designed for limited spaces, especially in drinks machines and kitchen installa-
tions and can be operated horizontally and vertically.
The food quality of BRITA water fi lter products has been inspected and confi rmed by an indepen-
dent institute.
Note: The AquaQuell PURITY 300 product has been renamed PURITY 450 Quell ST as part of a
name harmonisation without any other technical amendments. Products of the PURITY size systems
with the size designators 300 and 450 are 100% identical. All system components with the names
300 and 450 are compatible with each other and can be freely combined (e.g. PURITY 450 Quell ST
fi lter cartridge can be used in AquaQuell PURITY 300 pressure vessel or PURITY 450 Quell pressure
vessel can be combined with AquaQuell PURITY 300 pressure vessel).
