Simply press and hold the start button on the lid until four bars appear on the display and flash twice. Now BRITA® MEMO will start the countdown. The flashing dot in the display’s bottom right-hand corner indicates BRITA® MEMO is working. The number of bars on the display indicates the remaining lifetime of the water filter in weeks, with one bar disappearing each week.
You should replace your water filter at least every four weeks. This way you’ll enjoy optimum performance from your BRITA® water filter.
