All Mitte cartridges have a best-before date of 180 Days starting from cartridge activation. Although cartridges can be used past 180 Days, we can only guarantee optimal mineralization and filtration for this period. It is for this reason that we do not recommend using the cartridge after the 180 Days best-before date.
Mitte Water app users can find the best-before date displayed in Cartridge & CO₂ tab, as seen in the image below:
When the best-before date for the inserted cartridge has passed, and you press one of the water selection buttons, the LED on top of the device will show a fast white and orange alternating pulse and the cartridge LED will blink three times.
Please note: Earlier Mitte Home firmware versions also have a cartridge shut-off, full details of cartridge shut-off can be found in our "What is cartridge shut-off?" help centre article. We recommend keeping your device firmware up to date at all times to assure the best functionality. Please contact our Customer Success team if you require assistance with updating your firmware.
