[NSF Certified performance]: The system is certified against NSF 58 for TDS reduction.

In just a few minutes, Waterdrop RO system can be installed completely, and in just three seconds, the filter can be changed with one single turn. Installation is that easy
[The first composite filter element]: It is the first smart RO system with composite filters and tankless design in the U. S. market. The three filters provide seven stages of filtration. The pre-sediment and carbon block filter is a 3-in-1 filter that functions as that of three filters combined. The Reverse Osmosis membrane filter adopts an innovative design, and the efficiency of the filter equals more than three stages of filtration. Additionally, the activated carbon block filter uses high-precision activated carbon granules made from natural coconut shell, which will also improve the water taste
[No-tank design]: Use new composite filter element technology to more efficiently filter out harmful substances. The tankless design helps you avoid secondary pollution and enjoy more storage space in your kitchen
[No waiting for clean water]: Thanks to its internal pump, the RO system offers faster water flow (400 gallons per day). The system can filter a cup of water in about 12 seconds. It can produce pure water quickly, thereby meeting the needs of your whole family and even small companies
[1: 1 low drain ratio]: Compared to traditional RO systems, Waterdrop Reverse Osmosis Water Filtration System saves water waste by 300%. Save money on your water bills while running the RO system
[Special notice]: You must fully turn on the faucet and flush the RO system for 30 minutes after installation. The light on the faucet will flash blue during flushing, but once completed, the blue light will stop flashing. The total water capacity will be about 8. 5 gallons and the water will be undrinkable during flushing. To save water, be creative and collect the water for other purposes, such as watering plants
