Britta Water Filter Cartridges, how long do they last?
I have a Britta jug type water filter with a timer in the lid which tells me to fit a new filter about every month.
How accurate is this device or is it designed to sell more of the very expensive filter cartridges before they are actually needed
A month is about right. Over the month you will see differences in the taste and the speed of how long the water takes to filter.
A month is about right.
Don't get the Britta ones go and buy store brand ones which are universal
