Waterdrop X12 review: Fast tankless reverse osmosis filter with great taste, smart features and easy tap access

The Waterdrop X12 has an impressive 11‑stage filtration system that starts with a sediment pre‑filter, moves through a carbon filter, then the reverse‑osmosis membrane, and finishes with a re‑mineralisation stage that restores essential minerals, delivering water that is both pure and palatable.

Sleek, smart and seriously fast filtered water on demand. Picture: Waterdrop.

Can a tankless system replace a long-standing favourite? After seven years with my Berkey gravity filter, I put the new Waterdrop X12 to the test. Offering superior filtration and a rapid flow rate, this reverse osmosis system is easy to install yourself, providing the ultimate convenience: perfectly filtered water, straight from the tap.
