Waterdrop K6 Instant Hot Reverse Osmosis Dispenser System

Pure Water & Hot Water — All in One Smart System

The Waterdrop K6 combines high-performance reverse osmosis filtration with instant heating, delivering both purified and hot water directly from your under-sink unit. It’s ideal for kitchens, tea/coffee lovers, baby formula prep, cooking, and more.

Key Features

• 5-Stage Integrated Filtration
  The K6 uses a 5-in-1 composite filter (including RO membrane, carbon block, PP cotton, etc.) to reduce TDS, PFAS, fluoride, heavy metals, nitrate, chlorine, and more.

• 600 GPD Flow Rate
  Capable of producing up to 600 gallons per day, ensuring steady output even under high demand.

• Adjustable Hot Water (104 °F – 203 °F)
  Instant hot water ready in seconds, adjustable across a wide temperature range.

• Smart LED Faucet Display
  Shows real-time TDS levels, filter life, and dispensing temperature status.

• Safety Protections
  Includes child lock, dry-burn prevention, overheat protection, and flow/NTC sensors.

• Pure-to-Drain Efficiency: 2:1
  For every 2 gallons of purified water, 1 gallon is discarded — better than many traditional RO systems.

• Stainless Steel Heating Tank & Scale Prevention
  Designed to resist scale buildup and maintain performance over time.
