Comparison Bosch TWK 7601 white vs Zelmer CKE820 2200 W 1.7 L white

A small mesh (usually at the spout) that catches scale flakes and small particles to prevent them from getting into the cup when pouring. Its convenience lies in the fact that the filter can be quickly removed, rinsed under the tap, or cleaned with a soft brush without taking the kettle apart and without fussing with citric acid every time just for a few "crumbs" in the drink. Unlike non-removable inserts or "for show" filters, the removable option is easier to keep tidy, clogs less, and stays neat for longer, especially if the water is hard and the kettle is actively used at home or in the office. In practice, this is useful when you frequently boil water for tea/coffee or children's drinks: the filter does not completely solve the scale problem inside, but it significantly enhances comfort because there is less residue in the cup and the taste remains cleaner.
