This is our most compact and high-performance system that is ideal for single faucet applications, ice-makers, and water fountain upgrades. It fits easily under the sink in your home, cottage, RV and boat, and provides safe drinking water that is convenient, low maintenance and environmentally friendly. Acuva’s system takes water purification to the next level of efficiency and convenience by utilizing two well-established and proven technologies: UV and LED. The Acuva UV-LED chamber exposes harmful microorganisms such as bacteria to the UV dose recommended by the NSF Standard. Our proprietary design allows for the UV rays to be concentrated directionally, maximizing effectiveness. The Spark 2.0 UV-LED water purification system is compatible with 12V DC or 110V or 240V AC (using power adapter) and will be active only when system is being used for water purification. The on-demand capabilities provided by the Spark’s flow sensor will activate UV-LEDs only when water is flowing through the system, improving energy efficiency and extending the life-time of the system.
