The BWT AQA nano reliably reminds you when the active unit needs to be changed. The AQA nano hygiene unit comes with practical hygienic gloves. This optimally supports the hygienic replacement of the cartridge.

Changing the limescale protection unit 
The limescale protection unit has to be changed as soon as the control lamp for the limescale protection is out. For hygienic reasons, always change the filter unit together with the limescale protection unit. Proceed as for changing the filter sock, but also remove the limescale protection unit with the latex glove and immediately recycle it together with the glove.
