2 General Information
2.1 Function and Application
PURITY C is a fi lter system specially designed by BRITA for use in catering to ensure constantly high
water quality for individual customer applications as well as reliable and simple operation.
The unique IntelliBypass ensures a constant by-pass proportion of water for the entire usage period,
irrespective of the volumetric fl ow of the terminal equipment used. The result is consistently high
water quality specially tailored to the requirements of the application and the local water conditions.
By reliably locking the fi lter cartridge in the fi lter head and controlling the water fl ow, the innovative
locking handle ensures simple and reliable operation.
The food grade quality provided by the BRITA PURITY C fi lter system has been tested and confi rmed by
independent institutes. Product-specifi c certifi cations are located on the label and also at www.brita.net.
2.1.1 PURITY C Quell ST
PURITY C Quell ST fi lter cartridges reduce the carbonate hardness in drinking water, thus preventing
scale deposits in the downstream terminal equipment. Depending on the by-pass setting, calcium,
magnesium and metal ions can be selectively removed from the drinking water during the fl ow process.
In addition to cloudiness and organic pollutants, the fi lter material also reduces the level of substances
impairing smell and taste, such as chlorine residues in the fi ltrate and in the by-pass water.
Typical areas of application for PURITY C Quell ST are coffee and espresso machines, hot and cold drink
vending machines as well as combi ovens and conventional ovens.
2.1.2 PURITY Finest C
The PURITY Finest C fi ltrate helps to produce the unique coffee aroma – especially in espressos –
and allows the body of the coffee to develop. The characteristics of the coffee crema are experienced
in their full intensity.
The PURITY Finest C fi lter cartridges reduce the total hardness in drinking water, thereby avoiding
limescale and gypsum deposits in the downstream appliance.
Calcium, magnesium and metal ions are selectively removed from the drinking water using the
fl ow method.
