Countertop Reverse Osmosis System with Instant Hot and Cold Water
The Waterdrop A2 gives you purified water on demand without plumbing or drilling. Just fill, plug in, and use. It is a strong option for homes, offices, garden rooms, and any space where you want filtered hot and cold water without installation work.
Zero Installation, Easy Everyday Use
The Waterdrop A2 is designed for convenience. There is no need for pipework, no drilling, and no permanent fitting. It is suitable for kitchens, offices, bedrooms, conservatories, and mobile homes where a standard under sink system is not practical. The refill design makes it easy to use day to day, while the child lock and colour coded temperature lighting help make operation safer and more intuitive.

Deep Filtration with Reverse Osmosis Performance
Using a 0.0001 μm RO membrane and 5 stage filtration, the Waterdrop A2 is designed to reduce a broad range of unwanted contaminants from drinking water.
- Lead
- Arsenic
- Chromium VI
- PFOA and PFOS
- Fluoride
- Chlorine
- Copper
- Salt
- TDS
- Sediment
This makes it a strong choice for households looking for cleaner tasting water without a permanent installation.

Hot and Cold Water at the Touch of a Button
The Waterdrop A2 offers water temperatures from 10°C to 95°C, helping you choose water that suits drinking, cooking, and everyday use. Preset dispensing volumes also make it easier to pour the amount you need.
Dispensing options
4 oz = 118 ml
8 oz = 237 ml
16 oz = 473 ml
20 oz = 591 ml
The display shows the real time water temperature while dispensing, helping you stay in control.

Certified Performance and Smart Monitoring
The Waterdrop A2 is NSF ANSI 58 certified for reverse osmosis performance. That means it has been independently tested against recognised standards for contaminant reduction and system safety.
The smart screen helps you monitor TDS and filter life, so you can keep track of water quality and maintenance with less guesswork.
The composite filter design also keeps replacement straightforward, making routine ownership easier.
