Good investment with regular exchange

Use the filter for some time and have found that the coffee tastes more digestible. These differences in taste can of course from region to region differ because each waterworks provides a different quality. However, this filter is for everyone but a good investment.

The filter should be changed every two to three months. Regardless whether one prepared only one cup per day or ten, as the filter from the first use anyway "works" and wears off with time.
