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.

One machine, every kind of water.
Still, sparkling, hydrogen-enriched, vitamin-dosed, at any degree from ice to boil. Nobody else puts all six in one machine.
Every capability above ships in every Opus, from the $6,500 Core to the Atelier flagship. No feature tiers, no upsells.
The last showerfilter you'll buy.
You already know what chlorine does to skin and hair, and what most filters do about it: a thimble of media in a plastic tube, exhausted in a month. Monolith XL is the correction — six stages in an oversized 316L chamber, machined like the fixture it is. From $549.

We got tired ofthe compromises.
No plastic contact
No plastic tubing or tanks inside a Cuiven system. Lines and vessels are 316L stainless steel, titanium, and borosilicate glass.
Oversized by design
Compact filters exhaust in weeks because their chambers are small. Ours carry four times the media and go months longer between changes.
Components that outlast the house
Marine-grade metals, modular internals, and housing warranties that run fifteen years to lifetime.
Made in America
Designed, machined, and assembled in Wilmington, North Carolina. Every unit is pressure-tested before it ships.
