LED display and dual water mode: The integrated LED display notifies the water temperature and filter life to enhance the user's perception of the status of the sink faucet water filter. This function ensures the effectiveness of water treatment, facilitates maintenance and management, and provides an optimized user experience. The dual water mode allows for quick switching between raw water and filtered water to meet different water requirements. Innovative UV blue light technology: Equipped with UV blue light to enhance water purification. The unique turbine magnetic field sensor generates kinetic energy through water flow, without batteries. Combining advanced technology and exquisite design. The display is powered by a hydroelectric system, which can only work in filtered water mode. (Applicable to water pressure range: 0.1Mpa-0.4Mpa) Reliable carbon fiber filter element: The activated carbon filter element has strong adsorption power and provides a long-lasting service life. The physical water pressure effect at the water outlet ensures an even and gentle water flow. The filter body is made of food-grade material, which is safe and reliable.
