  • Description

The Waterdrop K6 is a revolutionary undersink reverse osmosis system that combines 5-stage deep filtration with instant hot water delivery — giving you purified drinking water at temperatures from 104°F to 203°F on demand. Powered by a 600 GPD flow rate, the K6 fills a 6 oz cup in just 6 seconds, making it fast enough for the busiest household while its 2:1 pure-to-drain ratio keeps water waste low. Advanced 5-stage RO filtration reduces TDS, PFOA, PFOS, chromium, fluoride, chlorine, radioactive particles, heavy metals, and more — certified by IAPMO R&T to NSF/ANSI 372 for lead-free construction. The smart dual-display faucet lets you select your exact water temperature and volume, monitor real-time TDS levels, and check filter life at a glance, with built-in safety features including child lock, dry burn protection, and temperature alerts. The compact, tankless design installs under the sink in about 30 minutes with no plumber required, making it perfect for modern kitchens where space and convenience matter.
