The Waterdrop G3P800 is a tankless under sink reverse osmosis system delivering 800 GPD fast flow with a 3:1 pure-to-drain ratio, certified by NSF/ANSI 42, 53, 58, and 372 for safety and performance. Featuring 10-stage filtration tested by SGS, it effectively reduces TDS, PFAS, fluoride, heavy metals, salts, and other contaminants while providing a cup of purified water in just 5 seconds. Its smart faucet displays TDS levels and water quality at a glance, with a long-lasting LED light that activates automatically with water flow. With a stylish, space-saving design, the G3P800 consistently produces clean, safe water for large families without the need for a storage tank.

• 𝗡𝗦𝗙/𝗔𝗡𝗦𝗜 𝘀𝘁𝗮𝗻𝗱𝗮𝗿𝗱 𝗰𝗲𝗿𝘁𝗶𝗳𝗶𝗲𝗱: This tankless reverse osmosis system is certified by IAPMO R&T against NSF/ANSI 58 for reduction of TDS. Also it has been tested and certified against NSF 42 to reduce chlorine, bad taste and odor.
• 800 GPD high capacity, 3:1 pure to drain ratio: The Waterdrop G3P800 reverse osmosis system offers a higher water capacity (800 gallons per day), thereby meeting demands of a big family for pure water. Furthermore, by high water flow, it filters one cup of water in just 5s. By an advanced water dispensing technology, this tankless RO water filter system produces just a cup of wastewater for every three cups of filtered water produced.
• 10-Stage filtration: Tested by official third-party laboratory (SGS), through 10-stage filtration, G3P800 can effectively reduce PFAS, fluoride, heavy metals like lead, chromium, iron, salts like nitrate and chloride as well as large particles and radioactive substances such as radium. Our RO system can reduce such as vinyl chloride, ethylhexyl acrylate, isobutylene, monobutyl ether, according to the reverse osmosis membrane technical manual.
• Smart faucet: G3P800 is equipped with a smart faucet, by which you can get the TDS level and water quality at a glance. The lifespan of LED lamp is up to 50 years. The LED can be automatically turned on when water flows by.
• Stylish look, tankless design: The RO system G3P800 has a stylish look. The tankless design saves under sink space and ensures the safety of water. The system can consistently produce water and ensures purity in every drop. You can get purified water anytime without waiting.
