Talk to a water expert
The Waterdrop K6 combines a 600 GPD under-sink reverse osmosis system with an instant-hot smart faucet, dispensing both purified cold water and near-boiling water at the sink. Tea, coffee, and cooking prep skip the kettle entirely.
Five filtration stages centered on a 0.0001-micron RO membrane reduce lead, chlorine, fluoride, arsenic, nitrates, PFAS, VOCs, and dissolved solids. The tankless design keeps the cabinet open and avoids storage-tank stagnation.
The composite filter is rated for 12 months or roughly 1,100 gallons, with a quick twist-out replacement.
