To continue enjoying fresh water in the best drinking quality every day in future, without worries, you should replace the filter on your UJETA Home & Travel at the latest after 6 months, or after around 5,000 litres of cold water. Under some circumstances earlier replacement can be necessary, for example if the water flow perceptibly reduces or if there is build-up within a shorter period due to heavily contaminated pipes. Too high a water pressure, or incorrect use, may also make earlier replacement necessary.
