The Vortopt DR2 reverse osmosis system has been certified to ensure its outstanding performance and safety. It has received NSF/ANSI 42 certification, proving its effectiveness in reducing impurities such as chlorine, taste, and odors. Unlike traditional reverse osmosis water filtration systems that occupy a large amount of space, the Vortopt DR2 under-sink filter uses a tankless design, optimizing the use of space under the kitchen countertop. 【Efficient Purification】Vortopt reverse osmosis system, 1000 gallons per day, with a flow rate of 0.69 gallons per minute, and a pure water to wastewater ratio of 3:1, reducing water waste by 1200% compared to traditional reverse osmosis systems. 【Smart Display】Uses a smart faucet that can monitor TDS in water in real-time. In addition, when the filter needs to be replaced, the faucet will alert you, saving you the trouble of bending down to check the filter's lifespan. 【Level 7 filtration】 can effectively reduce PFAS, fluorine, lead, chromium, heavy metals, chlorides, and large particles. Unlike traditional RO filters, our filter not only further absorbs odors and residual chlorine but also improves the taste of the water.
