2 General Information
2.1 Function and Application
PURITY C is a fi lter system specially designed by MAVEA 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 nearly constant by-pass proportion for the entire usage period,
irrespective of the volumetric flow 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 filter cartridge in the filter head and controlling the water flow, the innovative
locking handle ensures simple and reliable operation.
The food quality provided by the MAVEA 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.mavea.com.
2.1.1 PURITY C Quell ST
PURITY C Quell ST fi lter cartridges reduce the carbonate hardness* in drinking water, thus prevent-
ing 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 sub-
stances impairing smell and taste, such as chlorine residues in the fi ltrate and the by-pass water.
Typical areas of applications for PURITY C Quell ST are coffee and espresso machines, hot and cold
drink vending machines as well as combi ovens and conventional ovens.
