The tea processing device comprises a water tank, a water filter (1) present in the water tank for processing drinking water, with a housing (2), a filter material arranged in the water filter, a suction line connector for the suction of water from the water tank with means for producing a lower pressure, and a filter connection for the connection of water filter in the interior of the tank. The filter material comprises a first weak-acid cation exchanger in hydrogen form that receives 30-70% of the volume of ion exchanging material, and a second cation exchanger in sodium- or calcium form. The tea processing device comprises a water tank, a water filter (1) present in the water tank for processing drinking water, with a housing (2), a filter material arranged in the water filter, a suction line connector for the suction of water from the water tank with means for producing a lower pressure, and a filter connection for the connection of water filter in the interior of the tank. The filter material comprises a first weak-acid cation exchanger in hydrogen form that receives 30-70% of the volume of ion exchanging material, and a second cation exchanger in sodium- or calcium form, where the filter material is arranged in a filter chamber. The filter material is surrounded by the housing and a filling degree of >= 95% is provided in a closed cartridge. The water filter is formed as suction filter. The suction line connector of the water filter is arranged in the base area or lower area of the water filter at the tank side. The first cation exchanger is arranged in the filter chamber processed in exhaust flow or upward flow. The volume of the filter chamber processed in exhaust flow in water filter receives a portion of greater than 40% of total volume formed from exhaust flow or upward flow filter chamber. The weakly acidic cation exchanger loaded in the water filter is formed up to 70% of the active group in the mixture of sodium and/or calcium. Compression means are arranged for one of both cation exchangers in the water filter. One of the cation exchangers is formed in the water filter as compression means for the filter stretches formed through the cation exchangers. The filter material is arranged in a first filter chamber so that the filter material is filled in the second filter chamber in a volume reduction of the filter material in the second filter chamber for retrofilling of the volume of the second filter chamber. An overflow edge is formed in the water filter between the first filter chamber and the second filter chamber so that the filter material is filled from the first filter chamber into the second filter chamber in the volume reduction of the filter material in the second filter chamber for retrofilling of the volume of the second filter chamber. The filter volume has a height-to-width-ratio of less than 1.0. An independent claim is included for a water filter. |
