Cuiven / Precision Water Systems
Water,perfected.
Purification instruments machined from steel and titanium — for the water you drink, and the water you live in.
Our Conviction
Water is the first thing you touch each morning and the last thing you taste at night. It deserves the same obsession as everything else in the house — so we machine it like an instrument, measure it like a science, and finish it like an heirloom.

We got tired ofthe compromises.
No plastic contact
Water never touches polymer inside a Cuiven system. Every wetted surface is 316L stainless steel, titanium, or glass.
Oversized by design
Standard filters exhaust in weeks because their chambers are small. Ours carry four times the media and work for a year.
Components that outlast the house
Marine-grade metals, modular internals, and a lifetime warranty on every housing we machine.
Made in America
Designed, machined, and assembled in Wilmington, North Carolina. Every unit is pressure-tested before it ships.
