8-stage water filtration efficiency: The tap water filter can reduce residual chlorine and remove sand and plankton from the water, while the fleece filter layer can remove sediments and large particles. Special anti-limescale material and carbon fibre filter elements filter out the smallest suspended particles and effectively prevent the formation of deposits. Thanks to the 8-stage high-efficiency fine filtration, the overall sterilisation rate exceeds 99%. LED display and two water modes: The integrated LED display provides information about the water temperature and filter life. This feature ensures the effectiveness of the water treatment, facilitates maintenance and management, and provides an optimised user experience. In dual water mode, you can quickly switch between raw water and filtered water to meet different water needs. Innovative UV blue light technology: Equipped with UV blue light to improve the water purification effect. A combination of advanced technology and exquisite design. The display is powered by a water-powered system which only works in filtered water mode. (Applicable water pressure range: 0.1 MPa-0.45 MPa) Easy installation: Plug-and-play function, easy installation without drilling. The kitchen sink water filter comes with 6 different adapter types, including thread adapters and universal connectors to fit a variety of taps . Note: In unfiltered water mode, no water flows through the filter, so the hydronic heating system is not activated and the display remains off. This is normal functionality and not a product malfunction. If you need to view the display information, make sure to switch to filtered water mode. 8-stage water filtration: Effectively removes chlorine, sand and sediment.
