1600 GPD Tankless Reverse Osmosis for High-Demand Kitchens
A high-capacity under-sink RO system with 11-stage filtration, alkaline mineralisation, a smart digital faucet and a 3:1 pure-to-drain ratio.
- 1600 GPD high-flow tankless filtration
- 11-stage filtration with 0.0001 μm RO membrane
- Calcium and magnesium remineralisation
- Smart faucet with TDS and filter-life monitoring
Why the Waterdrop X16 Stands Out
High-Flow Output
Designed for fast dispensing and larger household demand without a conventional storage tank.
Pure-to-Drain Ratio
Produces three parts purified water for every one part sent to drain under rated conditions.
RO Filtration
Multi-stage treatment with a 0.0001 μm reverse osmosis membrane.
RO Filter Life
The X16-F3 RO filter is rated for up to 24 months, depending on feed-water quality and usage.
Built for Kitchens That Need More Water, Faster
The X16 is designed around high flow and a slim tankless format, helping preserve under-sink space while avoiding the waiting time associated with many lower-output RO systems.
Waterdrop states that the 1600 GPD system can fill a 6oz cup in around two seconds, making it well suited to busy kitchens, larger households and frequent cooking use.
- No bulky external storage tank
- Rapid dispensing for drinking and cooking
- Indoor under-sink installation
- Electricity required
Certified Reverse Osmosis Filtration
The X16 is certified to NSF/ANSI 42, 58 and 372 standards for the specific claims covered by its performance data. Waterdrop lists reduction of TDS, PFOA, PFOS, chlorine, fluoride, barium, arsenic, chromium VI, lead, microplastics, sediment, salt and odour.
TDS & Dissolved Salts
The RO membrane reduces dissolved solids and salts from the incoming water.
PFAS Compounds
Waterdrop lists PFOA and PFOS among the substances reduced by the X16.
Heavy Metals
Designed to reduce contaminants including lead, arsenic, barium and chromium VI.
Chlorine & Odour
Pre- and post-filtration improve taste and reduce chlorine-related odours.
Fluoride
Reverse osmosis provides effective reduction of dissolved fluoride.
Microplastics & Sediment
Multi-stage filtration removes fine particulate contaminants before dispensing.
Purified Water with Calcium and Magnesium Added Back
The X16 includes alkaline mineralisation after reverse osmosis. Waterdrop states that calcium and magnesium are added back into the purified water, with the system targeting a pH around 7.5±.
Water Quality and Filter Status at the Tap
The digital faucet gives you live information without opening the cupboard. It displays TDS information and filter-life status, while also supporting adjustable water-volume dispensing.
Designed for Everyday Convenience
- Real-time TDS display
- Filter-life reminders
- Adjustable water volumes
- Touch-control operation
Simple Scheduled Maintenance
12 Months
Primary filtration stage. Replace approximately every 12 months.
6 Months
Secondary filtration stage. Replace approximately every 6 months.
24 Months
Main RO filtration stage. Replace approximately every 24 months.
Actual filter life depends on incoming water quality and household consumption.
