The Franke 07 (FRF07) is the water conditioning cartridge for use with Franke Minerva 3 in 1 Kettle taps supplied pre October 2017. It is important, particularly in hard water areas, to change the cartridge every 6 months as advised to prevent limescale forming and protect the boiler.
IMPORTANT NOTE: The Franke 07 was the standard filter supplied with the Franke Minerva when it was launched in 2011 up until October 2017. In October 2017 Franke replaced the Franke 07 with the Franke Pro-M filter. If your system was purchased on or around that date we recommend double checking the label on the filter housing underneath the sink.
