Waterdrop X8 RO for Fast Under Sink Drinking Water

The Waterdrop X8 is an 800 GPD tankless reverse osmosis system designed for fast under sink drinking water filtration. Its nine stage filtration path, smart faucet, and 2:1 pure to drain ratio support efficient everyday use.

Best suited for: Households that want X Series filtration and smart status monitoring without the alkaline mineralization or higher output of the X12 and X16.

Why choose this system

Choose the X8 for 800 GPD performance, a narrow tankless footprint, and a simpler X Series configuration.

How this benefits your home

  • Cleaner tasting, lower TDS water: Nine stage reverse osmosis filtration supports a more refined supply for drinking, ice, coffee, tea, and cooking.
  • Faster everyday filling: The 800 GPD capacity supports busy household use without waiting for a storage tank to refill.
  • Less water sent to the drain: The 2:1 pure to drain ratio produces two parts filtered water for each part of wastewater.
  • Potential savings on bottled water: A dedicated under sink supply can reduce recurring bottle purchases and packaging waste.
  • Maintenance without guesswork: The smart faucet shows TDS and filter life to support timely cartridge changes.
  • More room beneath the sink: The tankless design avoids a separate storage tank in the cabinet.
