NOTE!
f The non return valve is approved according DIN EN 13959 and affixed in the filter head
f Devices with boilers or water tanks such as coffee machines, etc... have to be cleaned, rinsed
and sanitized before operating the filter system to ensure the protection.
f In general for immunocompromised people and for babies it is recommended to boil the water
before use. This should be done for filtered and unfiltered water.
f For the protection against microbiological growth the filter contains a small amount of silver
(„bacteriostatic").* Therefore, there might be a harmless release of silver in concentrations below
the recommendations of the World Health Organisation (WHO). The term "bacteriostatic"
indicates that the system limits the passage or growth of bacteria that may already exist in the
incoming water.* It does not mean that the water leaving the system is safer to drink than the
water entering the system.
f Do not use with water that is microbiologically unsafe or of unknown quality without adequate
disinfection before or after the system
