The pre-carbon filter (1-2), suitable for AquaTru Carafe, removes bacteria, sediment and other large particles from the drinking water. The activated carbon also removes any chlorine taste from the water. Because the filter filters large particles, it should be replaced once every 6 months. This prevents your device from getting clogged.

Time for replacement?
AquaTru will indicate when it's time to replace a filter.The light of the relevant filter will then remain lit on the display on top of the device. You can then replace the old filter with the new one. Finally press the 'filter reset' button on top of the device.
