- 5-stage filtration reduces TDS, PFOA/PFOS, fluoride, arsenic, lead and mercury
- Dispenses both hot (104–203°F) and cold water on demand, ready in seconds
- Smart LED faucet shows TDS level, filter life and has a child lock
- 600 GPD flow with a 2:1 pure-to-drain ratio for less water waste
- Under-sink install, corded electric, 17.5"L x 6.7"W x 16.6"H
This is sold by Waterdrop's own storefront rather than shipped and sold directly by Amazon, though it does ship from an Amazon warehouse. The instant-hot function is the draw here — useful for tea, coffee or soup without a kettle — but reviews are split on long-term reliability and whether the price holds up, so it suits someone replacing an aging RO system more than a first-time buyer chasing the cheapest option.
