The Bosch Aqua water purifier collection for under the sink combines an elegant housing with simple installation, handling and cleaning. Supported by a colour TFT display (Aqua 6600 P) not only the water quality is displayed but also the status and lifetime of each individual filter. Furthermore, a colour LED ring indicates the water quality directly at the tap, without the need to open the under-sink case. The filter can be replaced easily and quickly.
