Aquaporin Inside

All of our products contain aquaporins, the proteins responsible for transporting and purifying water in all living cells. Billions of years of evolution have made aquaporins super-efficient and super-selective, far better than any man-made water filter.

By incorporating aquaporins into our biomimetic membranes, we enable you to tailor-clean water faster and more energy-efficiently than ever before.

Drinking water

Universal access to clean drinking water is one of the world's biggest challenges.

In many areas, including Europe and the United States, water resources are at risk and public trust in drinking water is under pressure, leading consumers to seek alternative solutions.

Industrial water

Get one step closer to Zero Liquid Discharge, with less pre-filtration, less cleaning and reduced CAPEX and OPEX.

business critical improvements to dialysis machine design

With populations aging and water scarcity an increasing global problem, healthcare providers are looking for dialysis treatment options that reduce water use and can be performed at home.

The answer is a new generation of water treatment solutions that can reduce water use during in-center treatment by 75%, while paving the way for smaller and lighter portable home dialysis machines.

zero - water purification system

With ZERO, we wanted to achieve the impossible: A compact, beautiful object capable of filtering tap water without needing electricity, pumps, motors, control units or external water storage tanks.

ZERO is the highest performing, most compact reverse osmosis system to go under the sink. Smaller than a briefcase, ZERO delivers drinking water at 3 liters per minute from the moment the tap is turned on. If you need more than is held in its tank, leave the tap on and ZERO will go on producing, never needing to stop.
