We have very hard water and a Britta water filter for coffee maker and kettle. The filter of PearlCo UNIMAX are the perfect alternative to the relatively expensive Britta original water filters, keep at least as long and fit perfectly. We change the filters not every 4 weeks (Britta water filter indicator on) but every 6-8 weeks. The Maker of regularly in use must be almost no more decalcified (max. 2 times a year). However, we use the water not to drink directly from the Britta water filter, but is due to the personal taste and our tap water tastes just not us. Should this water be drunk directly, it is advisable to filter more often likely to change also due to bacteria in the filter. The application is similar to light as the original Britta filters, briefly soak them in water and let it run through, use it.
