Waterdrop G2P600 Reverse Osmosis System, 600 GPD Reverse Osmosis Water Filter, 7 Stage Tankless RO Water Filter System, Under Sink RO System, 2:1 Pure to Drain, Reduce PFAS, FCC Listed, USA Tech Extra WD-G2CF Filter, Replacement for WD-G2-W, WD-G2-B, WD-G2P600-W Reverse Osmosis System 7-stage filtration: The Waterdrop G2P600 reverse osmosis system adopts a composite filter technology, can reduce most contaminants. The CF filter employs a sediment PP membrane and an activated carbon block to reduce rust, sediment and organic matter. The MRO filter uses a 0.0001-micron reverse osmosis membrane, a sediment PP membrane, an activated carbon block and a PET pleated membrane to intercept TDS, salt, nitrates, PFAS, fluoride and heavy metals, etc. 600 GPD fast water flow: As an upgraded reverse osmosis system, the G2P600 tankless reverse osmosis system produces 600 gal. of filtered water per day. With a fast and stable water flow rate, this RO system fills a 200 ml cup with water in 8 seconds, which is ideal for drinking, washing vegetables and fruit. The G2P600 RO water filtration system also meets the water needs of big families and companies.
