Instant filtered water from cold to near boiling in one compact countertop system
The Waterdrop A1 is ideal for households that want purified drinking water on demand without drilling, plumbing, or a fixed under sink installation. It combines reverse osmosis filtration, chilled water, hot water, and smart controls in one neat unit that is suitable for kitchens, offices, bedrooms, and living spaces.
Advanced filtration performance
With a 0.0001 μm reverse osmosis membrane, the Waterdrop A1 is designed to reduce a wide range of unwanted contaminants while delivering purified hot and cold water from one countertop unit.
It is presented as reducing more than 1,000 impurities, including:
- Lead
- PFAS
- Arsenic
- Chromium
- Radium
- Fluoride
- Nitrate
- Iron
- Calcium
- Chloride
- Large particles
The dual water tank design and built in sterilisation support cleaner storage and day to day use.

No plumbing required
The Waterdrop A1 is made for easy plug and play use. There is no drilling or plumbing involved, so you can place it where you need it and start using it straight away.
It is well suited to kitchens, offices, bedrooms, and living areas where a fixed reverse osmosis system is not practical.
Its 2:1 pure to drain ratio, separated feed and wastewater design, and focused filtration path also help support more efficient operation and membrane life.

Flexible temperature control
This dispenser delivers cold water at around 5°C and offers a wider dispensing range up to 95°C, making it suitable for chilled water, room temperature drinking water, and hot drinks from one appliance.
Five standard cup volumes and six preset temperatures help make daily use quicker and more convenient for the whole household.

OLED smart display and easy touch control
The smart display is designed to show water quality, dispense volume, temperature, and filter life clearly. Touch controls keep operation simple, while features such as night mode, away from home mode, and altitude mode add flexibility.
Night mode is especially useful in homes and offices where quieter operation is preferred.

Built for safer everyday use
The Waterdrop A1 includes a three colour ambient light system to help indicate temperature clearly, making it easier to use throughout the day and evening.
A child lock function adds an extra layer of protection, helping reduce the risk of accidental operation when hot water is in use.
The display system also supports multiple languages, including English, German, French, Italian, Spanish, Dutch, Polish, Swedish, and Turkish.
NSF certified materials
Certified against NSF 372 for lead free materials and supported by SGS testing, the Waterdrop A1 offers extra reassurance around material safety and build quality.
These certifications help confirm that the system has been assessed against recognised standards for safe use.

Easy filter replacement
Filters are designed for quick replacement, making maintenance straightforward without needing a plumber. Keeping a spare replacement filter on hand can help avoid downtime.
This is a practical system for households that want strong filtration without a high maintenance setup.
