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 being an increasing global problem, healthcare providers are looking for dialysis treatment options with reduced water use that 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 %, 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.

one – water purification system

ONE is designed with an eye for simplicity and exclusivity. The slim and aesthetic machine fits under the sink and comes as an all-in-one solution with filter, membrane and faucet. 

With only two cartridges and a replacement indicator on the machine, ONE is easy to install and use. The user friendliness continues, as ONE’s only maintenance requirement is cartridge replacement which can easily be done by oneself.

Collaborations to 
change the world

We want to change the world one drop of water at a time. But we can’t do it alone, so we work with other companies, universities and institutions who share our vision. Our global joint ventures, Aquaporin Garage – a startup hub for smart ideas, and Aquaporin Academy – where similar-minded students meet and work together – are all part of a global movement where we act together to protect our planet and change the world.

Accelerating the
UN Sustainable 
Development Goals

The UN Sustainable Development Goals (SDGs) take some of the most pressing challenges of our time and encourage people to take action to solve them. Goal 6 is clean, accessible water and good sanitation for all. We’ve been working towards this goal since our inception. Now, it’s time to accelerate.

In 2019, we joined the SDG Accelerator Program. This gives us the chance to work more comprehensively with the SDG goals, build new partnerships and alliances, and develop truly innovative solutions that will take us through the next decade and beyond.
