Waterdrop G2P600 Reverse Osmosis Water Filtration System is an all-in-one, intelligent water purification system with many innovative designs. Our under-sink water filter system is designed to be tankless, leaving out the gigantic and ugly water tanks used often in conventional water purifiers. And this compact reverse osmosis system can be easily put under the sink, saving more storage space, while avoiding secondary pollution. This is the water filter system for the home! Another innovative design is the internal pump, which raises water pressure. The water flow rate of the under-sink water filter can reach 600 GPD (gallons per day). This means you can get a cup of filtered water in just 8 seconds. The traditional RO system, however, filters water more slowly and stores water in the tank, which may cause recontamination and, therefore, cannot meet the goal of producing purified water. This quick water purification process meets the needs of your whole family and even small companies for purer RO water.
