Coffee makers with water filter

Water filter

— built-in filter to purify the water used in the coffee preparation process. According to the principle of operation, such devices are in many ways similar to filter jugs: a filter cartridge is installed in the water tank, through which the liquid passes “along the way” to the brewing unit. At the same time, the presence of a filter is indicated only for those coffee machines that were originally equipped with such a cartridge. The specific capabilities of the filter may vary, but anyway it will be useful if for one reason or another you are not sure about the quality of the water you use (or just want to have an additional guarantee just in case). However the filter elements must be changed periodically, which means additional costs.
