Dedicated to natural water treatment

We are a water tech company delivering innovative technology built on nature's own water filtration

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.

The most efficient water 
filtration technology

Aquaporin Inside® is the technology that drives all our products. Put simply, it’s a biomimetic membrane that incorporates aquaporin proteins to filter water faster and more energy-efficiently than ever before.

Flat sheet, hollow fiber, reverse osmosis and forward osmosis. All our membranes use Aquaporin Inside® to purify and clean water, and they are revolutionizing water treatment – in industries, homes and even in space.

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.

Food & Beverage

Today’s consumers are increasingly health-conscious and environmentally-aware – and they have high expectations of their food and drink. They want natural products, made with healthy and nutrient-rich ingredients. You can give them this with Aquaporin Natural Concentration Technology.


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.

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.

Protecting the world’s water

We’re here to make a difference. Aquaporin is built upon a commitment to fight the global water crisis and drive change. With our technology, we encourage responsible consumption of the Earth’s most valuable resource – water.

We work to eliminate the use of plastic bottles and ensure safer consumption of drinking water by improving the access to clean tap water and thereby addressing waterborne diseases. And we seek to ensure more sustainable production patterns by reducing wastewater volumes and the energy consumption of water treatment.
